Extract Files

Its never easy to remember how to extract, unzip, or untar a compressed file.  Here's some code to add to your Unix account .bashrc file so that you never need to remember the correct commands and flags to use.  Don't forget to run source .bashrc after you make the changes to the .bashrc file.

	extract () {
	if [ -f $1 ] ; then
	case $1 in
	*.tar.bz2) tar xvjf $1 && cd $(echo $1 | sed 's/.tar.bz2//') ;;
	*.tar.gz) tar xvzf $1 && cd $(echo $1 | sed 's/.tar.gz//') ;;
	*.bz2) bunzip2 $1 && cd $(echo $1 | sed 's/.bz2//') ;;
	*.rar) unrar x $1 && cd $(echo $1 | sed 's/.rar//') ;;
	*.gz) gunzip $1 && cd $(echo $1 | sed 's/.gz//') ;;
	*.tar) tar xvf $1 && cd $(echo $1 | sed 's/.tar//') ;;
	*.tbz2) tar xvjf $1 && cd $(echo $1 | sed 's/.tbz2//') ;;
	*.tgz) tar xvzf $1 && cd $(echo $1 | sed 's/.tgz//') ;;
	*.zip) unzip $1 && cd $(echo $1 | sed 's/.zip//') ;;
	*.Z) uncompress $1 && cd $(echo $1 | sed 's/.Z//') ;;
	*.7z) 7z x $1 && cd $(echo $1 | sed 's/.7z//') ;;
	*) echo "don't know how to extract '$1'..." ;;
	esac
	else
	echo "'$1' is not a valid file!"
	fi
	}
