-
-
- INTRODUCTION:
-
- REARJ is an archive conversion program designed to facilitate the
- conversion of LZH, ZIP, PAK, ARC, DWC, HYP, LZS, and ZOO archives to
- the ARJ format.
-
- Registered ARJ users can order an improved version of REARJ that
- offers !listfile selection and exclusion, file date-time selection,
- REARJ_SW environment variable support, skipping a conversion when
- the converted archive is larger, and other features. And more
- registered REARJ enhancements will be forthcoming.
-
-
- MAJOR FEATURES:
-
- Supports all major archiver programs (PAK, LHARC, PKZIP, ZOO, ARJ,
- PKPAK, DWC, HYPER, LARC, LHA).
-
- Supports file attributes within archives.
-
- Supports directories within archives.
-
- Supports converting archives within archives (ZIPs in a ZIP).
-
- Ensures reliable archive conversion with a file count and total size
- check.
-
- Supports the use of virus checkers and BBS ad removers.
-
- Supports recursive scanning through subdirectories.
-
- Optional logging of conversions.
-
-
- ********************
- * WORDS OF CAUTION:*
- ********************
-
- If you plan to convert many archives at one time, it is STRONGLY
- suggested that you make a backup of your hard disk. This is a wise
- precaution to take any time that you make major modifications to data
- on your hard disk drive.
-
- The standard REARJ conversion DOES NOT convert any archive comments
- and volume labels. They will be lost.
-
- Some of the other archivers have significant bugs which can cause data
- loss that REARJ cannot detect. It is not the purpose of this document
- to point out other program's shortcomings. I suggest logging the
- conversion output to a printer to facilitate checking for errors.
-
- If the archives you are converting will ONLY extract to absolute
- paths, you must use the /w option to set the working directory to an
- empty root directory such as a RAMDRIVE. This will allow extraction
- to the root.
-
- REARJ and the archiver executables must be located in the DOS PATH
- directories. This is due to REARJ creating and using a temporary
- directory.
-
- If you have changed the MS-DOS switch character from "/" to another
- character via an undocumented MS-DOS interrupt or the TurboC
- setswitchar() function, REARJ may not work properly with the default
- REARJ.CFG configuration file.
-
- The most thorough testing was done with ARJ as the target format and
- ZIP as the original format. In any case, you should verify that the
- extract commands of your favorite archive formats in the configuration
- file are correct. The extract commands are the most important to get
- right because REARJ has a built-in verification procedure to ensure
- that the ADD commands executed properly.
-
- You should NOT set the "-t1" option for ARJ in ARJ_SW or in the
- REARJ.CFG configuration file. This may cause file size mismatches.
-
- Be sure you have enough disk space on your working directory to
- extract the largest archive that you want to convert!!!
-
-
- The versions of archivers tested:
-
- ARJ 1.00, 1.10, 2.00, 2.10, 2.20, 2.21, 2.30, 2.41a, current release
- LHA 2.12, 2.13
- PAK 2.51
- PKZIP 1.10
- PKPAK 3.61
- ZOO 2.01, 2.10
- DWC A5.01
- LARC 3.33
- HYPER 2.5
-
-
- INSTALLATION:
-
- Copy REARJ.EXE and REARJ.CFG to one of the DOS PATH directories. They
- do not have to be placed in the same directory. The PATH directories
- are usually set by the PATH command in your AUTOEXEC.BAT file. At
- this version of REARJ, changing its name to something else will cause
- operation difficulties.
-
- Be sure the archiver programs (ARJ, PAK, PKZIP, PKUNZIP, etc.) and
- virus scanner are installed in a DOS PATH directory! It is STRONGLY
- recommended that the REARJ.CFG be modified to use FULL PATHNAMES to
- specify all archiver executables.
-
- This version assumes that you have the new SCAN version 80 and use
- the new option /sub to scan subdirectories. This version's
- configuration file also assumes that SCAN.EXE is installed in
- the directory C:\BIN.
-
-
- OPERATION OF REARJ:
-
- REARJ will build a temporary directory in the current directory and
- extract the archive(s) to this directory. REARJ will then build the
- target archive(s) with the files in this directory. If the target
- archiver does not support reading of hidden or system files, REARJ
- will reset those bits and then re-archive the files without those
- attributes. If the original archive has directories in it, REARJ will
- extract it with full paths and re-archive it with full paths if the
- target archiver supports directories. In this case, if the archiver
- does not support directories, REARJ will skip converting this archive.
-
- If the "/a" option has been selected, REARJ will execute REARJ to
- convert any internal archives of the same type to the target format.
- Any "/s" option will be carried over to the recursive REARJ command.
-
- As an extra test, REARJ will count the files extracted from the
- original archive and total their sizes. Then REARJ will extract the
- new archive and count the files and total the sizes. If the count and
- size do not match, REARJ will skip converting the archive.
-
- REARJ assumes that the supported archivers will pass a non-zero error
- code when there is an operation failure.
-
-
- COMMAND SYNTAX:
-
- REARJ [switch options] filespec(s) or wildspec(s)
-
- You can specify one or more filespecs on the command line. These
- filespecs can have paths and wildcards. Up to 100 filespecs can be
- accepted by REARJ. If you specify *.* as a wildspec, REARJ will look
- at all filenames, but will skip those filenames not ending in standard
- archive suffixes. If you specify the /r switch, REARJ will look for
- filenames matching the filespec(s) in the current directory and all
- subdirectories of the current directory.
-
- The switch options and filespecs can be entered in any order. REARJ
- uses the default MS-DOS switch character "/". REARJ uses the Turbo
- C++ function getswitchar() to determine the MS-DOS switch character.
- If the switch character is "-", REARJ will translate any UNIX style
- pathnames to MS-DOS syntax ("dir/file" to "dir\file").
-
-
- SWITCH OPTIONS:
-
- /a - convert archives within archives
-
- This option causes REARJ to recursively execute REARJ to convert
- any archives of the original type found within the original
- archive (ex. ZIPs within a ZIP). This option requires additional
- memory to execute successfully.
-
- You may specify the type of internal archive to convert with the
- "/a" option.
-
- Examples: REARJ *.zip /aLZH convert only internal LZH archives.
- REARJ *.zip /a* convert any internal archive.
-
- If you use the "/a*" option, you may need to also specify "/u"
- because of nested archives of the target type.
-
- /b - execute command before extracting files
-
- This option is used to specify a DOS command to be executed before
- extracting the original archive.
-
- In addition, REARJ passes the name of the original archive to
- this command as a command line argument when executing it. This
- may cause a problem with DOS commands that expect no arguments.
- A workaround would be to install the DOS command in a batch file.
-
- This feature is to allow the user to prep the environment before
- extracting the archive. This can be used to prep for archive
- comments or volume labels, etc.
-
- /c - execute command on extracted files before counting them
-
- This option is used to specify a DOS command to be executed upon
- the extracted files before REARJ counts them for later
- verification. This is to allow executing a DOS or batch command
- to clean up the extracted files (remove BBS advertisements, etc).
- REARJ does not check for any returned error code from the
- executed command.
-
- In addition, REARJ passes the name of the original archive to
- this command as a command line argument when executing it. This
- may cause a problem with DOS commands that expect no arguments.
- A workaround would be to install the DOS command in a batch file.
-
- /d - delete the original archive
-
- This option causes REARJ to delete the original archive after a
- successful conversion to the target format. This option will NOT
- delete read-only archives.
-
- /e - do not return error if no archives were found
-
- This option is used by the internal recursive REARJ. This option
- will cause REARJ to return a zero exit code if no matching
- archives were found. Usually, REARJ returns a non-zero exit
- code for this condition.
-
- /f - convert diskette archives
-
- This option is used to facilitate the conversion of archives on a
- diskette. If you do not have sufficient space on the diskette to
- keep the original archives, you MUST specify the "/d" option as
- in "REARJ A:*.zip /f /d".
-
- This option causes REARJ to build the target archive in the
- CURRENT directory (not the working temporary directory). After
- verification, REARJ will, if specified, delete the original
- archive and then copy the new archive to the diskette. You
- should make sure that the current directory does not contain any
- archives before executing REARJ.
-
- /i - check program integrity
-
- This option causes REARJ to validate the REARJ program on disk.
- If you are using a pre-3.0 MS-DOS revision, you will have to
- specify the full program name as in "REARJ /i\util\rearj.exe".
-
- /l - write conversion data to log file
-
- This option causes REARJ to open a log file and record each
- successful conversion in the log file. The default log filename
- is REARJ.LOG. You can specify the log filename as in
- "REARJ /lfilename *.ZIP". If the log file already exists, REARJ
- will append logging data to it.
-
- /o - overwrite existing target archive
-
- This switch is used to delete already existing target archives.
- This is not used for updating archives. Use the /u option for
- updating an archive.
-
- /q - query for each archive to convert
-
- This switch causes REARJ to pause and prompt the user for
- permission to convert individual archives. Note that REARJ will
- not prompt when skipping archives.
-
- /r - recurse through subdirectories
-
- This switch causes REARJ to look for archives in all included
- subdirectories as well as in the current directory. This switch
- allows the user to convert all archives on a hard disk with one
- command.
-
- /s - skip verify of file count and total size
-
- Skip the overhead of the file count and total size verification
- process. This verification costs an extra extraction, but this
- check is worth the time, especially when converting a large
- number of archives.
-
- /t - specify the target archive type
-
- The default target archive format is normally ARJ. This can be
- changed by building an external REARJ.CFG file. The first
- archive type is always the default format. To override the
- default format, the user can specify the /t switch as in
- "REARJ *.ZIP /tlzh". The previous example has specified that LZH
- is the target format.
-
- /u - allow update of archive with backup
-
- This switch is used to re-archive an archive, possibly to take
- advantage of improved compression. The original archive is
- backed up by renaming it with the backup suffix which by default
- is "BAK". You may specify another backup suffix with the /u
- option as in "REARJ *.ARJ /uar$" where the backup suffix is
- "ar$". Since this option creates a brand new archive, archive
- comments will be lost. Do NOT specify a "." in the suffix.
-
- /v - execute configured command on extracted files
-
- This switch is used to execute a configure command on the files
- extracted from the original archive. The intent is to allow
- virus scanning of the archive contents. The command must be
- specified in the REARJ.CFG file.
-
- The command may be placed in the REARJ.CFG file by inserting one
- line ahead of the archive commands. The line must start with the
- word "VIRUS" followed by a blank and the external command.
-
- Example: VIRUS scan /nomem *.*
-
- If the invoked command returns a non-zero error code, REARJ will
- skip the conversion of that archive and log the error as code 13.
-
- REARJ *.* /v
-
- /w - set working directory
-
- By default, REARJ creates a temporary working directory in the
- current directory. This option allows you to specify the working
- directory. The working directory must be EMPTY when invoking
- REARJ. This directory is used to hold the extracted files.
- This is NOT considered the current directory for /f use.
-
- Example: REARJ *.* /wd:\
-
- This option helps solve the absolute pathname extraction problem
- that some archivers have. If you set the working directory to an
- empty root directory, the archiver can extract to the root and
- REARJ will be able to find all of the files to re-archive them.
- However, this option will NOT work for internal archives that
- extract to absolute paths.
-
- /x - exclude filenames or wildnames from the conversion process
-
- You can exclude one or more files from the conversion process.
- The filenames can contain wildcards.
-
- REARJ *.ZIP /xONE.ZIP /xTWO.ZIP
-
- /z - simulate conversion process
-
- This switch causes REARJ to simulate the conversion process. No
- archives will be extracted, built, or deleted.
-
-
- EXAMPLES:
-
- REARJ *.ZIP this converts all ZIP files in the current
- directory to ARJ files.
-
- REARJ *.ZIP *.ARC this converts ZIP and ARC files to ARJ
- files.
-
- REARJ SOFT.ZIP this converts only SOFT.ZIP to SOFT.ARJ.
-
- REARJ A:*.ZIP /f /d convert ZIPs on A drive with deletion of
- each original archive upon successful
- conversion.
-
- REARJ *.ARC /r this converts all ARC files in the current
- directory and in subdirectories of the
- current directory to ARJ files.
-
- REARJ SOFT.ARJ /tZIP this converts SOFT.ARJ to SOFT.ZIP.
-
- REARJ *.ARJ /u re-archive all ARJ archives.
-
- REARJ *.* /v /wd:\ re-archive all archives and execute
- configured command on extracted files
- using d:\ as the temp directory.
-
-
- EXTERNAL CONFIGURATION FILE
-
- REARJ comes with a configuration file, REARJ.CFG, which supports
- conversion between the ARJ, ARC, LZH, PAK, ZIP, DWC, LZS, HYP, and ZOO
- formats. The commands PKPAK and PKUNPAK are used for ARC files. The
- command LHA is used for LZH files. You can change these defaults by
- editing the configuration file.
-
- The format of the configuration file is fairly simple.
-
- The first line can optionally specify an external command to be
- executed by REARJ when the "/v" option is selected. This line must
- start with the word "VIRUS" minus the quotes, followed by a space,
- followed by the external command. The external command MUST contain
- a fully specified pathname for security reasons.
-
- Example: VIRUS C:\BIN\SCAN /nomem *.*
-
- If you do not want to configure this item, DO NOT insert a blank line.
-
- Each archive format requires four lines in the file.
-
- The first line is the format suffix.
-
- The second line is the archive ADD command with a %s in the place of
- the archive name. Any other percent signs in the command must be
- preceded by "\" as in "\%". The ADD command should support directory
- inclusion and reading of hidden and/or system files. REARJ will parse
- this command line using the space character as the token separator.
-
- If your ADD command requires DOS piping as the ZOO archiver requires,
- you must precede the ADD command with the text "COMMAND /C ".
-
- Example: ARJ a -a -r -jt %s
- COMMAND /C STUFF *.* | ZOO aI %s
-
- The third line is the archive EXTRACT command with a %s in the
- place of the archive name. Any other percent signs in the command
- must be preceded by "\" as in "\%". The EXTRACT command should
- support directory recreation if the archive contains directories.
- The extraction of directories must be to child directories within the
- current directory. REARJ will parse this command line using the space
- character as the token separator.
-
- If your EXTRACT command requires DOS piping, you must precede the
- EXTRACT command with the text "COMMAND /C ". Beware that command exit
- codes are not passed back to REARJ when using COMMAND /C.
-
- The fourth line contains the letters "A" and/or "D" or no letters.
- The "A" stands for the ability to process files with the hidden and/or
- system attribute. The "D" stands for full support of directory trees
- within archives. No letters (blank line) stands for no support for
- hidden or system files or for archive containing directories.
-
- There must be NO EXTRA blank lines or comments in the file. You may
- use leading blanks for clarity.
-
- See the supplied REARJ.CFG for the current configuration.
-
- If you use a different archiver program, you will need to either
- rename the program to one of the supported ones or you will need to
- modify the installed REARJ.CFG file.
-
- If your original archive format supports extraction to absolute
- directory paths as opposed to relative directory paths and you have
- such archives containing absolute paths, you should not put directory
- extraction in the REARJ.CFG file unless you use the /w option to set
- the working directory to an empty root directory.
-
- You can add comment handling to the ARJ command by adding the
- "-zcomment.txt" option. This is supported at ARJ 2.20 and above.
-
-
- LOG FILE DATA
-
- When logging is enabled, REARJ will log the action on each selected
- file. For successful conversions, REARJ logs the date-time, target
- archive type, original archive size, new archive size, bytes saved,
- and original archive name.
-
- When selected files are skipped for any reason, REARJ will log an
- entry in the log file (when logging is enabled) which specifies the
- reason code for skipping the file. The following are the codes:
-
- 1 = File not found
- 2 = File is not a configured archive type
- 3 = Target archive already exists
- 4 = Not enough disk space
- 5 = User skipped or user did not select update option
- 6 = UNPACK error
- 7 = PACK error
- 8 = Target cannot support directories
- 9 = Wrong file count
- 10 = Wrong total size
- 11 = Internal archive REARJ error
- 12 = Rename archive error
- 13 = Invoked /v command error (found a virus?)
