CDPATH: Easily Navigate Directories in the Terminal
The CDPATH environment variable lets you pre-configure frequently used directories so you can easily navigate into them from anywhere in your file system1.
A cd
search path works like your command search path $PATH
. However, instead of finding commands, it finds the subdirectories. You can configure it with the shell variable CDPATH
, and it has the same format as the PATH
variable: a list of directories separated by colons.
Set this variable in your ~/.zshconfig
or ~/.bashrc
file to include the directories you visit most frequently.
export CDPATH=$HOME:$HOME/software:$HOME/software/js:$HOME/software/web
Now, whenever you want to cd
into a directory, the shell will look through all the above places in addition to the current directory.
What’s more, the search is lightning fast. It looks only in parent directories that you specify and nothing else.
For example, let’s say you have a $HOME/software/blog
directory and you’ve configured the CDPATH to include the $HOME/software
directory.
Now, if you type cd blog
from anywhere in the filesystem, the cd command will take you to the $HOME/software/blog
directory, unless it finds another blog
directory in another pre-configured path.
The order of
CDPATH
matters. If two directories in$CDPATH
have a subdirectory named blog, the earlier parent wins.
In the above example, cd
will check the existence of the following directories in order, until it finds one or it fails.
-
in the current directory
-
$HOME/software/blog
-
$HOME/software/js/blog
-
$HOME/software/web/blog
P.S. Don’t overdo it. If you put too many directories with common names into CDPATH and export
it, it might break your scripts.

z
does a great job of achieving the same outcome by tracking your most used directories, based on ‘frecency’. After a short learning phase, z will take you to the most ‘frecent’ directory that matches ALL of the regexes given on the command line, in order. Rather elegant, and I use it all the time. ↩
