How to grep ps output with headers

by 

ps -ef | egrep "GMC|PID"

Replace the “GMC” and ps switches as needed.

Example output:

root@xxxxx:~$ ps -ef | egrep "disk|PID"

UID        PID  PPID  C STIME TTY          TIME CMD
paremh1  12501 12466  0 18:31 pts/1    00:00:00 egrep disk|PID
root     14936     1  0 Apr26 ?        00:02:11 /usr/lib/udisks/udisks-daemon
root     14937 14936  0 Apr26 ?        00:00:03 udisks-daemon: not polling any devices

ps -e selects all processes, and ps -f is full-format listing which shows the column headers.
