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




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


Change directory to $HOME




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)"


There are 2 alternatives - vote for the best!

Terminal - Alternatives

What others think

Holy convenient. I hate having to erase filenames when I cut-and-paste.

I like those features. I'll have to rework my own cd function to include them on my boxes. (see #8253)
