I would like to list only directories (including hidden) in a given directory (for example /etc/) if I'm not in this directory.
If I want to list all directories, including hidden I use the command:
ls -d */ .*/ I wanted to use this command to list all directories in /etc.
ls /etc I can do this, but I wanted to combine it with the first one, listing only directories.
ls -d */ .*/ /etc or
ls /etc -d */ .*/ don't work. Why?
It doesn't work because */ and .*/ are not arguments that are passed directly to ls - instead, they are globs that are expanded by the shell, giving a list of matching filenames in the current directory that are themselves passed to ls
The equivalent for a different directory (/etc say) would be
ls -d /etc/*/ /etc/.*/ If your shell supports brace expansion, you can write that more compactly as
ls -d /etc/{,.}*/ 
find /etc/ -maxdepth 1 -type d Use above command to list only directories including hidden directory being in some other directory
