Getting pids from ps -ef |grep keyword

Question

I want to use ps -ef | grep \"keyword\" to determine the pid of a daemon process (there is a unique string in output of ps -ef in it).

I can kill the pr

Answer 1

ps -ef | grep KEYWORD | grep -v grep | awk '{print $2}'

Answer 2

To kill a process by a specific keyword you could create an alias in ~/.bashrc (linux) or ~/.bash_profile (mac).

alias killps="kill -9 `ps -ef | grep '[k]eyword' | awk '{print $2}'`"

Answer 3

You can use pgrep as long as you include the -f options. That makes pgrep match keywords in the whole command (including arguments) instead of just the process name.

pgrep -f keyword

From the man page:

-f       The pattern is normally only matched against the process name. When -f is set, the full command line is used.

---

If you really want to avoid pgrep, try:

ps -ef | awk '/[k]eyword/{print $2}'

Note the [] around the first letter of the keyword. That's a useful trick to avoid matching the awk command itself.

Answer 4

This is available on linux: pidof keyword

Answer 5

Try

ps -ef | grep "KEYWORD" | awk '{print $2}'

That command should give you the PID of the processes with KEYWORD in them. In this instance, awk is returning what is in the 2nd column from the output.

Answer 6

I use

ps -C "keyword" -o pid=

This command should give you a PID number.
