UNPACK - Info
Unpack automates the process of extracting source tarballs to a fixed location, by default $HOME/src or /tmp, after first checking that the tarball will create its own subdirectory. A directory is created based on the tarball filename if not. Unpack is written in Perl and was developed for Linux, but should run unmodified on most Unix-based systems, although a recent version of GNU tar is recommended..
UNPACK - Default extraction directory
The default "extraction" directory is the first directory succesfully found from:
- "DIR=" entry from $HOME/.unpackrc, i.e. contents of $HOME/.unpackrc should be something like:
DIR=/home/username/srcdir
2. $HOME/src;
3. /tmp
UNPACK - Examples
EXAMPLE 1
For a tarball with a 'good' top-level directory:
(e.g.
> tar -ztf project-1.2.tar.gz
project-1.2/main.c
project-1.2/const.h
project-1.2/README
...)
This will be unpacked as follows:
> unpack project-1.2.tar.gz

Identifying compression type ... gzipped tarball: OK Checking that archive extracts to its own directory ... Yes. Unpacking /home/username/project-1.2.tar.gz to /home/username/src ... OK
And the resulting files are in /home/username/src/project-1.2/...
EXAMPLE 2
For a tarball with no top-level directory:
(e.g.
> tar -ztf badprog-1.3.tar.gz
main.c
const.h
README
INSTALL
...)
This will be unpacked as follows:
> unpack badprog-1.3.tar.gz

Identifying compression type ... gzipped tarball: OK Checking that archive extracts to its own directory ... No. Creating path /home/username/src/badprog-1.3 ... OK. Unpacking /home/username/badprog-1.3.tar.gz to /home/username/src/badprog-1.3 ... OK
The extracted files are in /home/username/src/badprog-1.3 ...
