ls -l /proc/[1-9]*/fd/ | grep /tmp

Hi,

#lsof /tmp | more

lsof output will give you processes using /tmp .

To find out the largest files in tmp.

#cd /tmp

#ls -l | sort -nr -k 4,4 | more

( in descending order )

I just kill some of idle user , then the space used is normal now , but I still wonder why I can't find the strange process by top , how can I check what large process is running in the system ? thx

peter, a process will not show up on top unless its using a lot of cpu resources.

top is for top users of cpu. It doesn't take a lot of cpu on a busy system to fill up a disk.

Hi !

as Steven said, top is for the most CPU consumating processes. For you problem, you should better use lsof to detect the process then use the ps command. if you detect that is your writer, then use
ps auxw | grep
