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.
