The una package

[Tags:bsd3, program]

A simple universal unarchiving utility. Just point it at any archive or compressed file, and it spits out a single file or directory in the current directory with its contents. Use -d to delete the original archive on success. Use -f to overwrite any existing file or directory which might be in the way.

una: Universal un-archiver

Version 1.0, by John Wiegley johnw@newartisans.com

This is a "universal", recursive unarchiver, written because I'm too lazy to remember all the extraction options for the large number of archive formats I deal with.

Optional dependencies:

  • StuffIt Expander (free, expander-only version)
  • MacPorts: unarj, unrar, lha, p7zip, cabextract

Usage

una [OPTION] ARCHIVE...

If no OPTION is specified, the default action is to extract the archive's
contents into the current directory.

Options:
  -h, --help        show help
  -d, --delete      delete the archive if sucessfully extracted
  -f, --overwrite   overwrite any existing file

This script is also smart about unarchiving:

a) if all the contents of an archive would already extract into a single directory, do that;

b) if the archive contains only one item, extract it into the current directory;

c) otherwise, if the archive would dump multiple contents into the current directory, create a new directory based on the name of the archive, sans extension, and put everything there.
