that's called the "sticky" bit -- a term like most thing Linux left over from long ago and the meaning is now changed.

it is only valid (has an effect) on directories and not files

it sets the directory so only the creaters of files not others with write access can delete them..

i think its effect if for those people designated "other" chmod o+t <dirname>
and is used on world writable directories and i think (but might be wrong) that it is trumped by owner and group settings.

if it helps anything, my /tmp has it, which (if you think about it) makes a lot of sense (to me, anyways <0.01 wink>).
