What others think

You could get the "arg list too long error".

Use this instead:

find -maxdepth 1 -mindepth 1 -mtime +7 -exec rm -f {} +

or

find -maxdepth 1 -mindepth 1 -mtime +7 | xargs rm -f

Quite true. Though this has never happened to me with bash on linux (only sh on windows). Also you'd need to have an awful lot of files in the top level of your tree...

Comment by tatwright 271 weeks ago

Oooo, dangerous. Never use "rm -rf" on unescaped command lines. If there's (ugh) spaces in filenames, catastrophic things can happen. A filename with a period surrounded by space ("foo .") deletes everything under the current directory. A filename with a tilde separated by spaces ("foo ~") nukes your home directory.

Comment by sunny256 270 weeks and 6 days ago

Well, the tilde example doesn't delete the home directory in _this_ case (as the tilde isn't expanded), but there are other combinations where it could happen. In fact, for this kind of use it's better to use tmpreaper(1). It is meant for this kind of use, and it checks the access time instead of the file modification time. Because a file isn't modified in a week or so, doesn't mean it isn't used by processes in a read-only way.

Comment by sunny256 270 weeks and 6 days ago

Forget about expansion, just use find's delete capability:

find -mtime +7 -delete
Comment by bwoodacre 270 weeks and 4 days ago

@bwoodacre: does that delete dirs? and does it force delete (-f)?

Comment by sudopeople 270 weeks and 3 days ago

About the "arg list too long error" :

http://www.in-ulm.de/~mascheck/various/argmax/

it is quite safe since linux 2.6.23 as the arg list is valid till it doesn't fill the quarter of the stack.
