- CHANGES IN VERSION 5.21
-
-
- The following changes have been made in ARC version 5.21, but have not
- yet been included in the manual:
-
- o When adding files to an archive, ARC now shows the stowage facter
- achieved on each file.
-
- o A bug was found that would keep an archive entry from being
- encrypted if it was stored without compression. This has now been
- fixed.
-
- o If changes are made to a corrupted archive, the corrupted entries
- are discarded. This makes it possible to lose data accidentally.
- ARC will now only make changes to a corrupted archive if the W
- (suppress Warnings) option has been given.
-
- o The N (suppress Notes) option now suppresses the "Creating
- archive" note when a new archive is being created.
-
- o The N (suppress Notes) option formerly did nothing useful when
- used with the L (List files) command. It now causes a terse
- listing of filenames only, suitable for use with pipes and
- redirection.
-
- o The list of filenames given to ARC may now include indirect
- references. If a filename begins with an "at sign" ("@"), it is
- taken to be the name of a file which contains a list of file
- names. The list of file names may include further indirection.
- If no extension is given, ".CMD" is assumed. For example, the
- command:
-
- arc a waste junk.txt @trash
-
- would cause ARC to add JUNK.TXT plus all files listed in the file
- TRASH.CMD to an archive named WASTE.ARC. If no file is specified,
- then the list is read from standard input. For example, the
- command:
-
- arc ln waste | arc a trash @
-
- would cause ARC to add files to TRASH.ARC based on the names of
- the files stored in WASTE.ARC. It is probably a good idea to give
- the O (Overwrite) option if you are extracting files this way.
-
- Version 5.21 of MARC also allows for indirection.
