BASH: How to avoid displaying the last line in grep?

I'm parsing some information from ps -ef |grep process but it always displays in the output of grep the last line which is the grep itself. How can I get the output of grep without the last line? The output looks like that:

root@itaig-lt:~# ps -ef |grep gnome-terminal
itaig     3307  2306  0 09:37 ?        00:00:00 /bin/sh -c gnome-terminal
itaig     3308  3307  0 09:37 ?        00:01:58 gnome-terminal
root      7055  5047  0 13:37 pts/10   00:00:00 grep --color=auto gnome-terminal
root@itaig-lt:~#
Solution

  • You can do two things:

    Grep exluding the grep itself:

    ps -ef |grep gnome-terminal | grep -v grep

    or add a string condition that is not matched by this grep (see explanation):

    ps -ef |grep [g]nome-terminal
