Power cd - Add a couple of useful features to 'cd'

cd() { if [ -n "$1" ]; then [ -f "$1" ] && set -- "${1%/*}"; else [ -n "$CDDIR" ] && set -- "$CDDIR"; fi; command cd "$@"; }

Move efficiently between directories. . This command adds a couple of extra features to cd, without affecting normal use. CDPATH use is also unaffected. It introduces and environment variable CDDIR which is used as an alternate home directory. . Note: I don't want to alter $HOME because then all my dot files will move. . Examples: . cd dir Change directory to "dir" (using CDPATH if necessary) . cd dir/file.txt Change directory to "dir" (containing folder of "file.txt") This allows you to cut'n'paste, or use . CDDIR is unset cd Change directory to $HOME . CDDIR=/home/flatcap/work cd Change directory to /home/flatcap/work . For convenience, put the command, and the following, in your .bashrc or .bash_profile export CDDIR="/home/flatcap/work" alias cdd="CDDIR=$(pwd)"

Sample Output

~$ export CDDIR=/home/flatcap/work
~$ cd
~/work$ unset CDDIR
~/work$ cd
~$

I like those features. I'll have to rework my own cd function to include them on my boxes. (see #8253) http://www.commandlinefu.com/commands/view/8253/
