-i

Ignore case distinctions in both the process table and the supplied pattern.

Long output. pgrep prints the process name in addition to the process ID for each matching process. If used in conjunction with -f, prints the process ID and the full argument list for each matching process.

-P <PPID>

Restrict matches to processes with a parent process ID in the comma-separated list PPID.

-q

Do not write anything to standard output.

-U <UID>

Restrict matches to processes with a real user ID in the comma-separated list UID.

-x

Require an exact match of the process name, or argument list if -f is given. The default is to match any substring.
