BASH – A smart extract utility

Why This Script?
As a systems administrator or as someone who dabbles in compilation technologies, it often becomes necessary to extract one or more variety of compressed files/folders. This script will automagically handle the options necessary for uncompressing different kinds of compressions.
The script
#! /bin/bash # # BASH script to automagically uncompress different kinds of compressed files/folders # # Usage: extract.sh [COMPRESSED_FILENAME] # First written: Wed, 04 May 2011 05:14:10 -0400 # Last modified: Wed, 04 May 2011 05:14:10 -0400 # E_BADARGS=65 if [ $# != 1 ] then echo echo " Usage: `basename $0` [COMPRESSED_FILENAME]" echo exit $E_BADARGS else if [ -f $1 ] then case $1 in *.tar) tar -xvf $1 ;; *.tgz) tar -xvzf $1 ;; *.tar.gz) tar -xvzf $1 ;; *.tbz2) tar -xvjf $1 ;; *.tar.bz2) tar -xvjf $1 ;; *.gz) gunzip $1 ;; *.bz2) bunzip2 $1 ;; *.zip) unzip $1 ;; *) echo " '$1' file type unknown" ;; esac else echo " '$1' is not a regular file" echo fi fi |
Use it as a function!
Add the following lines to ${HOME}/.bashrc (and remember to source it).
# Smart extract function extract () { if [ $# != 1 ] then echo echo " Usage: extract [COMPRESSED_FILENAME]" echo else if [ -f $1 ] then case $1 in *.tar) tar -xvf $1 ;; *.tgz) tar -xvzf $1 ;; *.tar.gz) tar -xvzf $1 ;; *.tbz2) tar -xvjf $1 ;; *.tar.bz2) tar -xvjf $1 ;; *.gz) gunzip $1 ;; *.bz2) bunzip2 $1 ;; *.zip) unzip $1 ;; *) echo " '$1' file type unknown" ;; esac else echo " '$1' is not a regular file" echo fi fi } |
Nice litte script, g. This is certainly a handy time-saver when doing repetitive decompression with several different algorithms and file types.
