Is there a built-in command or a less verbose way of achieving this?
find /var/foo -maxdepth 1 -mindepth 1 -type d
Or should I just make a tiny shell script or function if I'm doing this sort of thing often?
The shortest command seems to be
I believe that will non-recursively list all the subdirectories of
Below is my original self-answer.
If one cares not about files beginning with a dot then mibus' answer of
would be short and effective. However if one would like the hidden files to be included then one needs to either stick with
The -F places / and the end of directory names (as well as other characters for other types of files). The -A causes files starting with a dot to be included, except for '.' and '..'. That is why -a is not used. The grep won't get any false positives since '/' is not allowed in filenames (at least for POSIX filesystems).
Regarding performance, on my Ubuntu Jaunty installation with just shy of 32k files and directories in /var/foo, find is the fastest, followed by ls -d, and ls -FA with grep comes in last.
"-d" means don't delve into the directories, the "*/" only matches directories.
