why can't I remove my own files

hi experts

quick question here:
I created a file under tmp as test. but when I tried to remove it, I couldn't. I get permission not permitted. Is it because tmp is owned by root and therefore I have to be root to do it?

Thanks

Code:

test@test-virtual-machine:/tmp$ who
test     pts/8        2015-06-14 20:01 (192.168.15.1)

test@test-virtual-machine:/tmp$ ls -lart

-rw-rw-r--  1 test test 2480 Jun 14 20:05 appendit

test@test-virtual-machine:/tmp$ rm appendit
rm: cannot remove ‘appendit’: Operation not permitted

Correct.

You should be able to delete that - sounds like the /tmp wasn't set up correctly with the restricted deletion flag (aka sticky bit).
Have you moved /tmp ?.

I stand corrected.

Though the file has rw permissions for your user and you can edit it but deleting requires correct permission of the directory containing it. Your /tmp should have rwx permissions for your user.

The usual permission for /tmp is '1777'.

Set it with:

Code:

chmod 1777 /tmp

try using the super user privileges

sudo su
