prok

easy process grep with ps output

Prok: easy process grep with ps output

Usage: prok [--user <USERNAME>] [--uid <UID>] [-fmp1239] [--SIG<SIGNAL>] [<PATTERN>]

Parameters:
    -f --forest         print parents of all matched PID's.
                            On linux prints with 'ps f'
    -m --my             match only processes of current user
    -p --procname       match only executable, not full command
    --user USERNAME     match only processes of USERNAME
    --uid UID           match only processes of UID(numeric)

    --kill              ask to kill all matched processes
    --SIG<SIGNAL>       do killing with this signal. e.g. --SIGKILL
    -1 -2 -3 -9         do killing with signal's numeric alias
                            Be cautious with -f option, it'll bring whole forest down

Examples

let's spawn some processes:

server:~/>sleep 20000 &
[2] 31029
server:~/>sleep 20000 &
[3] 31061
server:~/>sleep 20000 &
[4] 31093
server:~/>sleep 20000 &
[5] 31125
server:~/>sleep 20000 &
[6] 31157
