This can prevent 'grep' from showing up in ps results

$ ps aux  | grep terminaluser  2064  0.0  0.6 181452 26460 ?        Sl   Feb13   5:41 gnome-terminal --working-directory=..user  2979  0.0  0.0   4192   796 pts/3    S+   11:07   0:00 grep --color=auto terminal


可以使用下面方法,就可以去掉grep --color=auto terminal這一行的顯示

$ ps aux | grep '[t]erminal'

user  2064  0.0  0.6 181452 26460 ?        Sl   Feb13   5:41 gnome-terminal --working-directory=..
