It can store several files in one archive in a compressed form which is generally more efficent than that used by Arc and Zoo. It also supplies all of the archive handling capabilities that an archive program should have. In particular it is able to store an entire directory tree (including empty directories) with one single command. This enables you, for example, to store an entire floppy-disk with a single command and the resulting archive is usually shorter than those prodeced by Warp or even LhWarp (see the -r switch). Another important feature of Lharc is its ability to preserve the file attributes (see the -a switch) and filenotes (i.e. the comments that AmigaODS can associate to each file). Its only weakness is compression speed: Zoo 2.0, for example, is faster, but if compression efficency is more important for you than compression time you'll surely appreciate this progam. (anyway decompression is much faster than compression) --- Before starting --- Lharc is a 'pure' program, i.e. you can make it resident via the 'resident' Amigados command just like any other command found in the c: directory. Keeping Lharc resident will greatly facilitate users who make an heavy use of Lharc (especially those who don't have an hard disk). If you have just received Lharc, beware that some copy programs and some archivers (including the zoo archiver which is used for distribution of Lharc) don't preserve file attributes, so the 'p' flag may not be set for the Lharc executable and Amigados won't understand that Lharc is a pure program. If so, just type the following line at the CLI prompt: protect Lharc p add --- How to use --- Lharc is run from CLI with the following command line: Lharc [<switches>] <Command> <Archive> [<dest path>] [<file patterns>] items in square brackets are optional. <Command> can be any of the following (case is not significant): e,x extract files from archive Extracts files from archives. If you specify some file names or patterns only those files satisfying the patterns are extracted, otherwise all the files in the archive are extracted. While extracting files, Lharc checks if a file by the same name already exsists in the destination directory and prompts you before overwriting the old file with the extracted one (unless you specified the -m switch) By default, if the files have a path name stored in the archive, they are extracted with their path and needed directories are automatically created; use the -x0 switch to ignore path names. See below under '<dest path>' for a discussion on where the extracted files are stored. l show archives contents Displays the names of the files in an archive along with their date, time, CRC, compression type, original lenght and compressed lenght. If the -x switch is specified file names are listed complete with their path (if present in the archive), otherwise only the name of the files is listed. The 'l' command won't list the comments (filenotes) that may be assiciated with a file: use the 'v' command to see them, too. v Same as 'l', but default is to display full pathnames: i.e. the 'v' command is equivalent to the 'l' command with the -x switch; on the other hand the 'l' command is equivalent to the 'v' command with the -x0 switch. Moreover 'v' will also show any filenote (i.e. comment) associated with the files; filenotes, if present, are listed on a separate line preceded by a colon (i.e. in the same format used by the AmigaDOS 'list' command). p extract and print files to screen same as 'e' and 'x', but extracted files are sent to stdout t test archive integrity Checks CRCs and checksums to ensure that the archive is not corrupted. Lharc will test all the files on the archive, one after each other, printing "OK" to the right of the file names which are OK and "WARNING: CRC check failed" to the right of file names that are corrupted. At the end of the test the message "Operation successful" means that all the files tested were OK, while the message "Operation not totally successful" means that some files in the archive were corrupted (so you will know of a corrupted file even if the warning message relating to that file has scrolled away on the screen) a create archives or add to existing archives Files are stored in alphabetical order, unless you change this with the -S switch. Note however that sorting only applies to the files beeing added in the current session, i.e. if you add files to an existing archive containing other files, the new files will be stored, in alphabetical order, AT THE END of the archive: old and new files won't be intermixed to preserve global alphabetical order. If you try to archive a file and a file by the same name already exists in the archive the file will not be added and a message will be printed on the screen to inform you. By default only file names are stored in the archive, use the -x switch to store file names complete with their paths. Also, by default file attributes are not stored, use the '-a' switch to obtain this. m move files into archivs Same as add, but deletes original files after archiving them d delete files from archives You can delete from an archive a maximum of 150 files at a time, if you find that they are too little, please let me know! u update files in archives Same as with the 'a' command. However, if a file already exists in the archive, LHarc will check its time stamp and will keep the newer one and ignore the older one. f freshen files in archives Replaces a file in the archive with the newer one only if a file with the same name already exists in the archive. Otherwise, no action is taken. <Archive> is the name (eventually preceded by a path) of the archive you want to work on. If no extension is specified the default extension .LZH is used. With the 'l' (or 'v'), 'e' (or 'x'), 'p', 't' and 'a' commands you can work on multiple archives by using wildcards (see 'file patterns' below for a list of accepted wildcards). For example "lharc v *.LZH" will show the contents of all the archives in the current directory, while "lharc x *.LZH *.c" will extract all the C source files contained in all the archives in the current directory. [<dest path>] This parameter is significant only with the 'x' (or 'e') command. It tells where to put the extracted files; if not specified, extracted files will go to the current directory. Please note that this paramenter must always end with '/' or ':' otherwise it will not be recognized as such and will be considered as one of the file patterns. If the path specified by <dest path> (or equivalently the path stored in the archive) does not already exist, you will be prompted if you want new directories to be automatically created (unless you specified the -m switch, in which case directories will be created without any prompt). [<file patterns>] rappresents an optional number of file names or file patterns. They indicate which files to extract/compress/list/delete, ecc. Accepted wild cards are the standard AmigaDOS '#' and '?' plus the '*' which is a synonim of '#?'. Since however the asterisk is a valid caracter in AmigaDOS file names I provided the '**' sequence as an escape. So if you want to refer to a file name containing an asterisk just double the asterisk in the file name. Example: '*.c' is equivalent to '#?.c' and refers to all the files ending with '.c', while 'my**file' refers to the file 'my*file'. [<switches>] rappresents an optional number of switches that are used to change the behaviour of the program. A switch is composed by a leading '-' followed by one letter; unlike commands which are case insensitive, switches are case sensitive. An important point is that if you want to specify more than one switch, every switch must be preceded by its own dash, i.e. to activate the 'x' and 'm' switches you must enter "-x -m" and NOT "-xm". You can store your favourite switch configuration in an environment variable (see below) so that you don't have to type them every time. All the switches that don't take a parameter can be followed by a '0' which turns off the function, while the switch alone or the switch followed by a '1' turns the function on: i.e. -x means "use extended file names", while -x0 means "don't use them". So you can override the default settings or the settings you specified in the environment variable "LHARC". Default value for every switch is off, exept for the -a switch which is on with all the commands and for the -x switch which is by default on with the 'x' 'e' 'd' 't' and 'v' commands and off with the other commands. Here is a summary of the available switches: -p (p)ause after loading [note that this is lowercase 'p'] Causes Lharc to wait for the user to press RETURN before executing a command. This allows floppy disk users to swap disks after loading Lharc. -m no (m)essage for query Suppresses all the queries Lharc normally issues before overwriting existing files or before creating new directories If you specify this switch Lharc will behave as if you choose the default action (indicated by an uppercase letter) in response to all the questions. This switch also disables autoshowing of files (see 'Autoshow files' below) -x use e(x)tended file names By default, LHarc stores only the file names of files and disregards the names of the directories in which they reside. This switch, used with the 'a' command, tells LHarc to extend all file names with directory names; with the 'x' 'e' 'd' 't' and 'v' commands the -x switch is automatically turned on: use -x0 if you want to turn it off thus ignoring pathnames with these commands. -n no progress i(n)dicator Suppresses the display of the number of bytes beeing processed during compression or decompression. May be useful if you redirect to a file the output of Lharc. Note: this version of Lharc allows the -N switch as a synonim of -n : but this might change in future versions, so preferibly use the lowercase letter. -w set (w)ork directory Use this switch to choose your own directory for temporary files. The directory name must immediatly follow the letter 'w' without any leading space, i.e. to set the 'temp' directory on your hard-disk as the working directory you must write "-wdh0:temp". See below "Temporary files" for a discussion on where temporary files are stored in the absence of this switch. -P set (p)riority [note that this is uppercase 'P'] Use this switch to set the priority with which Lharc will be executed. Priority must be in the range -5..+5 and must immediately follow the 'P' letter without blanks in between. By default Lharc is excuted with the same priority of the task that invoked it; using this switch will set the new priority immediatley after loading and will set back the priority to the original value immediately after terminating. If you want to do something else with your Amiga, for example editing a letter, while Lharc is compressing a long file, I suggest that you set Lharc's priority to one less than that of the other program, i.e. if you started your editor with the usual priority of zero then invoke Lharc with the '-P-1' switch to set its priority to -1 -a consider file (a)ttributes Lharc can ignore file attributes (i.e. the flags indicating protection from deletion, and so on) for maximum compatibility with the MSDOS version: in other words it can store files with an attribute bit pattern which is suitable for MSDOS machines and, during extraction, ignore the attributes stored in the archives, setting the attributes of the extracted files to the usual '----rwed'. Alternatively Lharc can preserve the protection bits by storing them in the archive and then restoring them during extraction. In Lharc version 1.3 and higher, this switch is by default on, i.e. file protection bits will be preserved: use -a0 to turn it of to achieve full MSDOS compatibility. Remember that, to effectively preserve file attributes, you must use the same setting for this switch both during compression and during extraction. Of course AmigaDOS file attributes are meaningless to MSDOS and vice-versa; so extract files with the -a switch only if you are sure that they contain AmigaDOS file attributes and similarly compress files with the -a switch only if you are sure that the archive will be unpacked only by Amigas and not by MSDOS machines. (Anyway no harm is done if this rule is not respected: extracted files will simply have strange attributes) -u convert file names to (u)ppercase By default Lharc stores file names/paths with thier original case, if you use this switch they will be converted to uppercase. See below 'Compatibility' for a possible use of this switch. -r (r)ecursively collect files This switch instructs Lharc to search for files matching the specified patterns not only in the specified directories, but also in all the subdirectories that may be found in the specified directories. For example: "Lharc -r a archive.lzh df1:source/*.c" will search for files whose name ends with ".c" in "df1:source/" and in all the subdirectories that may be contained in the "df1:source" directory. Another example: "Lharc -r a archive.lzh df1:*" will archive the entire disk in drive df1:, including all its subdirectories. Very powerfull, isn't it ? The -r switch can optionally be followed by a 'e' (i.e. -re): this tells Lharc to store empty dirs as well. By 'empty dir' we mean dirs which are actually empty or dirs which contain no files matching the patterns specified on the command line. This option allows you to perfectly re-create a directory tree, but remember that archives containing empty dirs are NOT compatible with MSDOS-Lharc 1.13; so, use the 'e' option only if you are sure that the archive you are producing will be unpacked on Amiga machines only. When you specify the -r switch, files are always stored with their path name, i.e. the -r switch automatically turns on the -x switch, too. -S Set (s)orting criteria [note that this is an UPPLERCASE S] This switch sets the sort criterium for files beeing added to archives. The '-S' must be immediatly followed by one to four characters, i.e. -Sxyzw where 'x' can be any of the following: 0 Don't sort files a Alphabetical sort [default] c Chronological sort 'y', if present, can be any of the following: a Ascending order [default] d Descending order 'z', if present, can be any of the following: i Case insensitive alpha-sorting [default] s Case sensitive alpha-sorting 'w', if present, can be any of the following: l Local sorting [default] g Global sorting The above parameters must be specified in the order given above, for example to choose between local or global sorting you must necessarly also specify the three preceding parameters. The -S0 option is useful if you want to create an archive in which files appear in a given order: the -S0 switch tells Lharc to add files in the same order as they were specified in the command line (or in the '-i' file). The 'global/local sort' parameter needs some more explaination: 'global sorting' means that files will be stored in strict alphabetical or chronological order; 'local sorting' means that sorting will be local to each subdirectory with more 'nested' subdirectories pushed at the end of the archive. As an example, look at the following lists of files: the left coloumn is sorted with alpha-global sorting, the right one is sorted with alpha-local sorting GLOBAL SORTING LOCAL SORTING Announcement Announcement README README include/common.h include/common.h include/foo/abc.h include/global.h include/foo/rexx/rexx.h include/rexxbind.h include/foo/rexx/rexxglue.h l/xyzzy-handler include/global.h lib/ps.library include/old/foo/abc.h s/.xyzzyrc include/old/poof/xyz.h s/add-2-startup-sequence include/poof/poof.h src/Makefile include/poof/xyz.h src/foo.c include/rexxbind.h src/poof.c include/xyzzy/incl1.h src/xyzzy.c include/xyzzy/incl2.h src/zot.c include/xyzzy/incl3.h utils/help l/xyzzy-handler utils/more lib/1.3/foo.library include/foo/abc.h lib/1.3/old/foo.library include/poof/poof.h lib/2.0/foo.library include/poof/xyz.h lib/ps.library include/xyzzy/incl1.h s/.xyzzyrc include/xyzzy/incl2.h s/add-2-startup-sequence include/xyzzy/incl3.h src/Makefile lib/1.3/foo.library src/foo.c lib/2.0/foo.library src/old/poof.c src/old/poof.c src/poof.c include/foo/rexx/rexx.h src/xyzzy.c include/foo/rexx/rexxglue.h src/zot.c include/old/foo/abc.h utils/help include/old/poof/xyz.h utils/more lib/1.3/old/foo.library Finally some examples: -Scd Sort chronologically in descending order -Sc or -Sca Sort chronologically in ascending order. -S0 Don't sort at all -Sads Sort alphabetically in descending order (case sensitive) -Saail Sort alphabetically in ascending order; sorting will be case-insensitive and will be local to each subdirectory; this is also the default action which is taken if you don't specify this switch. -b Set I/O (b)uffer size Big I/O buffers can considerably speed up some operations of Lharc (espacially with hard disks) however if you are low on memory you may prefer to use small I/O buffers. This switch lets you set the amount of memory that Lharc will use as an I/O buffer: the number of Kbytes of memory to be used must immediately follow the 'b' without any spaces in between, e.g. -b20 tells Lharc to use 20 kbytes of memory for I/O buffers. Any number between 6 and 37 is valid, default is using 11 Kbytes: if you are low on memory you can lower this amount, but if you have plenty of memory I suggest that you rise it. I suggest that you set this switch at the value you like in the environment variable 'LHARC' (see below) so that you don't have to specify this switch every time you invoke Lharc. -f ignore (f)ilenotes By default Lharc archives files complete with their comment (filenote). If you set this switch, filenotes won't be stored in archives and files beeing extracted won't have any filenote even if it was present in the archive. There is no compatibility problem, but if you are not interested in filenotes you may set this switch to reduce the archive size (filenotes are stored in uncompressed form, so if you have long filenotes they can increase the size of the archive). -d set archive's (d)atestamp By default archives created or updated by Lharc will have a datestamp corresponding to the date of creation of the archive. If you set this switch, on the contrary, archives created or updated by Lharc will have the same date as the newest file contained in the archive. -c (c)onfirm files If this switch is set, Lharc will ask you for confirmation before archiving or extracting a file. This allows you to specify a large set of files through the use of wild-cards and then select which of them to consider in an interactive way. If you for example typed: "Lharc -c a test.lzh *.c" all the files ending with '.c' in the current directory will be presented to you with the message: "Archive file xxx.c? [(Y)es, (n)o, (a)ll, n(o)ne]" You have four alternatives: to choose between them just type the letter indicated in parenthesis and press return. The '(Y)' is printed in uppercase to remember you that this is the default action which is taken if you simply press return. The meanings of the four alternatives are: yes: archive the file no : don't archive the file all: archive this file and all the following files without asking anymore for confirmation. none: don't archive this file nor any of the following files This switch is ignored if the -m switch is active. -i read (i)nput from a file This switch tells Lharc to read the list of files to act upon from a file. The file name must immediately follow the '-i' without any speces in between. If the -i switch is specified alone (i.e. without a filename) the file list is read from stdin. For example: Lharc -idf1:list a foo.LZH will add all the files specified in the 'df1:list' file. This file can contain ordinary file names or file patterns to be added, each on a separate line: a file name is assumed to be terminated by a space or a tab, everything on the line after the first space or tab is ignored. If a file name contains spaces, it must be enclodsed in double quotes. The ability to read the list of files from stdin allows the use of Lharc in a pipe of comamnds, for example: list since today | Lharc -i a foo.lZH will archive all the files in the current directory which were created today. (A shell that supports the '|' character is required) Note that you can also specify some files on the command line, if you want; the command: Lharc -idf1:list a foo.LZH hello.c bye.c will add the 2 files 'hello.c' and 'bye.c' plus all the files specified in the file named 'df1:list'. As mentioned above, although this is of less frequent use, you can also use the -i switch to supply a list of files to be extracted, printed, listed, ecc. Please note that, in this vesion of Lharc, the number of filenames or patterns that can be specified through the -i switch is limited to about 120: this limitation will be removed in the future. --- Setting switches in an environment variable --- You may set any of LHarc's default switches with the environment variable 'LHARC': So, if you, for example, want to always set the archive's date to that of the newest file in the archive, use the maximum allowed I/O buffer size and use 'dh0:mytemp/' as a working directory, you simply type: SenEnv LHARC "-wdh0:mytemp -d -b37" (don't forget the quotes): now Lharc will behave as if you typed the above switches every time you invoke it. You can insert the setenv command in your startup-sequence so that it's automatically executed every time you turn your computer on. Of course, you can always override the default settings estabilished in the enviroment variable with the command line: for example a '-d0' in the command line will override the '-d' found in the above enviromnet variable. Please note that the 'setenv' command is only available in Workbench 1.3 and higher: if you are using older versions of the O.S. this feature is not available. --- Autoshow files --- Suppose that your archive contains an important text file that you want to be sure it will be read by the guy who unpacks the archive. The file may for example contain a copyright notice or some special instructions for unpacking. For this purpuse Amiga-Lharc introduces autoshow files: while unpacking an archive, if Lharc encounters a file whose name ends with ".TXT.DISPLAYME" (case is not significant and quotes must not be included, of course), it first extracts the file (removing the .DISPLAYME extension) and then displays in a window the text found in that file waiting for the user to press RETURN before proceeding. You can add as many autoshow files as you want, for example one at the beginning and one at the end of the archive. Autoshowing of files is disabled when the -m switch is active so that a non-interactive unpacking session is allowed. Lharc uses the standard CON: device to open a window for displaing text, so you can insert ANSI codes in your autoshow files to make your messages nicer. Lharc will adjust the size of the window according to the number of lines contained in the text file, but the maximum allowed size is that of an NTSC screen (200 pixels), so if your text is longer than 20 lines it will scroll away. Finally, please note that this feature is unique to the Amiga version of Lharc (for now...) so remember that if your archive will be unpacked on another machine (or an an Amiga using Lharc version 1.0 or lower) autoshow files will simply be extracted without displaying them on the screen; anyway your important text file will still be there for later reading by the user and no compatibility problems will arise. --- Temporary files --- While compressing files Lharc creates a temporary file called 'Lharc.TMP_XXXXXX' where XXXXXX is a hex digit representing the address of its own Task structure as returned by Exec's FindTask(NULL). The reason for the XXXXXX part of the name is that if you run multiple copies of Lharc at the same time each copy will create its own temporary file with a different name (usefull for multiline BBSes for example). Here is how Lharc decides where to store temporary files. If you specify a path with the -w switch temporary files are stored there, otherwise if the T: logical device is assigned they will be stored in that directory, otherwise they will go to the current directory. If you are not using the -w switch, in order to increase compression speed, I raccomand that you assign T: to a directory in the ram-disk. Note however that T: is usually automatically assigned to 'ram:t' in the startup-sequence of the standard Workbench, so, unless you have modified the startup-sequence, you don't have to worry about this. --- Corrupted archives --- This version al Lharc for the Amiga has the capability of automatically handle corrupted archives. A Lharc archive is made up of several compressed files each precedeed by a header containing information about file name, date, lenght,... To ensure that the archive is not corrupted the header also contains a 16 bit CRC of the file and an 8 bit checksum of the header itself. If during extraction Lharc finds a corrupted file (i.e. one whose CRC does not match with the one stored in the header) the file is extracted anyway, but a warning is printed on the screen. The worst case comes when the header of a file is corrupted: in this case the file cannot be extracted even if the file itself is not corrupted. In this case Lharc will automatically skip the corrupted entry by starting a search for the next valid entry in the archive and will print a message like "WARNING: skipping extraneous/corrupted data" The reason for which it says "extraneous/corrupted" is that an Lharc archive might happen to contain parts that Lharc cannot recognize as valid archive entries even it's not corrupted. This happens when you are extracting files from a self-extracting archive produced by the MSDOS version of Lharc, since a self-extracting archive contains 8086 extraction code which the Amiga-Lharc sees as extraneous data. The only extraneous data which is passed without warnings is additional bytes at the end of an archive: since they are likely to consist of zero padding due to XMODEM transfer they are totally ignored. --- Return codes --- When Lharc finishes his work, it returns to the operating system one of 3 possible return codes: 0 Everything was OK (the message "Operation successful" is printed on the screen). 5 Lharc finished its work, but something went wrong, for example Lharc encountred a corrupted entry in the archive, but was able to continue extracting/testing the rest of the archive (the message "Operation not totally succesful" is printed on the screen). 20 A fatal error occurred and Lharc was unable to continue its work (an appropriate message exlpaining the probelm is printed on the sceen) Thus you can test the succes of operation in your script files by means of the 'failat' statement and the 'if warn' test. --- Bugs --- No known known bugs remain in this version. ---- Compatibility --- This program is aimed at full compatibility with the MSDOS version 1.13 of Lharc. A few little problems might arise from some file names that are legal under AmigaDOS, but illegal under MSDOS. As a matter of facts AmigaDOS allows a wider range of file names (almost every caracter in the ASCII set is allowed and file names can be longer than 8 characters). For the greatest convenience of Amiga users, I choose not to restrict the file name range to accomplish the MSDOS rules, but if you expect that your archives will be unpacked on an MSDOS machine you'd better rispect the MSDOS limits. Also note that, although MSODS Lharc version 1.13 CAN extract files whose names contain lowercase letters, its pattern matching functions don't work properly with lowercase file names. So if you want to extract an Amiga-created archive on an MSDOS machine by using pattern matching functions (for example to extract only some files instead of the whole archive) you have to create the archive on the Amiga with the -u switch. Finally, to attain 100% compatibility you shuold not use the '-a' switch nor the '-re' switch ('-r' alone is, on the contrary, OK) (see above in the descriptions of these switches for more details) Also note that the MSDOS version of Lharc has the additional capability of extracting files from archives produced by Larc (a pupular Japanise archive program): this feature will not be implemented in the Amiga version. ---- Acknowledgements --- First of all I give credit to Haruyasu Yoshizaki for devising such an efficent compression algorythm as LZHUF. Second, since the source to the MSDOS version of Lharc is scarcely portable (lots of 8086 assembler ruotines and MSDOS-dependent C functions), I had to rewrite the program from scratch. Note however that for LZHUF compression/decompression I have used as a starting point a 'C' source for an example of single file compression which I found on a BBS. Although the code has been now remanaged (and partially rewritten in assembler by Paolo Toccaceli and me) it nevertheless was invaluable to me. For sake of correctness I quote here the the header found on this source: /* * LZHUF.C English version 1.0 * Based on Japanese version 29-NOV-1988 * LZSS coded by Haruhiko OKUMURA * Adaptive Huffman Coding coded by Haruyasu YOSHIZAKI * Edited and translated to English by Kenji RIKITAKE */ I whish to thank the above people whose work has been of foundamental importance for this project. Thanks to Stefan Boberg for suggesting how to store filenotes in the archive structure that didn't provide space for them. Many thanks also go to all the people who contributed with suggestions and bug reports and particularly to Luca Spada for his invaluable beta testing work. --- How to contact me --- Please send suggestions, comments and bug reports to: Paolo Zibetti Fidonet: 2:331/101.6 Internet/UUCP: Paolo.Zibetti@p6.f101.n331.z2.fidonet.org node 2:331/101 (AmnesiA) is also the official distribution node for Amiga-Lharc: you'll always find the latest version available on this board.
