Is it possible to hide folders? [duplicate]

How can I hide folders without changing their names?

I want to hide some folders that I don't really want to hide all those folders that I don't use. Since system is using them I can't really rename them to add . in front of them. Is there any other way?

For hiding things in Nautilus (and maybe other graphical browsers) when you can't rename, you can create a file called .hidden in the current directory and list the paths you don't want shown.

For example if I have a direcory with subdirectories {a..f} and a .hidden containing:

b
c

ls -l shows everything still:

drwxr-xr-x 2 oli oli 4096 2011-06-29 23:02 a
drwxr-xr-x 2 oli oli 4096 2011-06-29 23:02 b
drwxr-xr-x 2 oli oli 4096 2011-06-29 23:02 c
drwxr-xr-x 2 oli oli 4096 2011-06-29 23:02 d
drwxr-xr-x 2 oli oli 4096 2011-06-29 23:02 e
drwxr-xr-x 2 oli oli 4096 2011-06-29 23:02 f

But Nautilus only shows:
