strange process

[peterchu]

I found that the available size of /tmp become smaller , it seems there is a process is running and write sth to the harddisk , but I can't find it by use "top" function , could suggest how to find it ? thx.

i tried to du -sk the /tmp , but the used size is the same ,

/dev/sda8 505605 479278 223 100% /tmp

I don't know why the space gone , could suggest what is wrong ? thx.

Hi,

try this command.

lsof /tmp

or

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

thanks.

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 )

thx all ,

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

[peterchu]

I got it , all are fixed. thank you very much.

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
