I often find myself wanting to cd to the various directories beneath my home directory (i.e. ~/Library, ~/Music, etc.), but being lazy, I find it painful to have to type the ~/ if I'm not in my home directory already. Enter CDPATH, as desribed in man bash):
The search path for the cd command. This is a colon-separated list of directories in which the shell looks for destination directories specified by the cd command. A sample value is ".:~:/usr".Personally, I use the following command (either on the command line for use in just that session, or in .bash_profile for permanent use):
This way, no matter where I am in the directory tree, I can just cd dirname, and it will take me to the directory that is a subdirectory of any of the ones in the list. For example:
[robg adds: No, this isn't some deeply buried treasure of OS X, but I'd never heard of the CDPATH variable, so I'm assuming it will be of interest to some other readers as well.]
$ cd $ cd Documents /Users/baumanj/Documents $ cd Pictures /Users/username/Pictures $ cd Preferences /Users/username/Library/Preferences etc...
