wtf is this?

[mandreko]

i was looking through permissions on my machine (I was bored) and i found a directory that had this:
drwxrwx--T

what is that "T"?

[mandreko]

maybe nobody knew since it was early when i posted..

Does anyone know this? could it be a security risk? it's on a tmp folder

[Shadoglare]

If I remember right it just means that it has a "sticky bit" applied to it, which means that only the owner and root can screw with it.

No security risk here. This is the sticky bit and it is quite commonly placed on the tmp directory. That way the directory is world-writable but a user other than the super user cannot delete files in it created by somebody else.
