NAME
arc - manages content within a compressed library file.
ALIASES
ARC, JAR, ZIP
SYNOPSIS
arc [OPTIONS] archive [FILES]
DESCRIPTION
ARC is a compression and file packaging utility. Files are stored in single
library usually with the .ZIP or .JAR extension. This is used to compress
files reducing storage space and to package multiple files in one library
that can be managed as a single entity.
-E
Extract - Extracts uncompressed FILES to their relative path locations.
To override the destination path use the -P option.
-A
Add - Compresses and adds FILES to an archive preserving their relative
paths. To override the stored paths use the -P option.
-U
Update - Compresses and updates FILES in the archive when the new files
have been more recently modified.
-F
Freshen - Scans the archive comparing the last modification dates with
any matching external files. If an external file has been modified more
recently it will replace the copy in the archive.
-M
Move - Same as -A adding FILES to the archive. Once the archive has been
successfully modified the added external files are removed. The
FILES are moved into the archive.
-D
Delete - Remove FILES from the archive.
-L
List - Display archive content. Use the -V verbose option for greater
detail.
-S
Recurses folders when wildcard file specifications are used.
-P pathspec
Overrides the destination path associated with a file. When
extracting this is affects the destination of the file(s).
When adding this defines the relative path stored for the file(s).
-V
Verbose output. Increases detail.
-O
Overwirte when extracting. If an external copy of the file
would be overwritten the action is confirmed. The -O option
bypasses the confirmation and overwrites as requested.
-T
Test the archive. This decompresses archive content and confirms
that each file can be successfully extracted. This uses stored CRC
information.
NOTES
JAR and ZIP archives are equivalently formatted archive files. The JAR
file is so named as it generally contains an application program for
the JNIOR written in Java.
In some cases a ZIP/JAR library forms a
virtual folder with the name of
the library (without the extension) located at that point in the file system.
That allows the JANOS Java Virtual Machine, Webserver and Help system to
access files directly out of archives. Programs and websites each require
multiple files in order to function properly and an archive file allows those
to be transferred and managed easily as a group.
With JANOS 2.4 the
CAT command can retrieve and display text content directly
from a virtual folder formed by an archive file. This can give you easy access
to the extended log files backed up by the optional JBakup utility.
