I want to examine the all the key files present in my /proc. But /proc has innumerable directories corresponding to the running processes. I don't want these directories to be listed. All these directories' names contain only numbers. As I am poor in regular expressions, can anyone tell me whats the regex that I need to send to ls to make it NOT to search files/directories which have numbers in their name?

UPDATE: Thanks to all the replies! But I would love to have a ls alone solution instead of ls+grep solution. The ls alone solutions offered till now doesn't seem to be working!

You don't need grep, just ls:

ls -ad /proc/[^0-9]*

if you want to search the whole subdirectory structure use find:

find /proc/ -type f -regex "[^0-9]*" -print
