How can I get only the PID of a process

like
ps -aef | grep "xyz"

It gives me pid but few other things also

I need only pid of process "xyz"

how can I do this?

I have to kill a process using shell script how can i do that

I tried the following
$a=pidof -s programname
kill -9 $a

but it's not working. Can anyone help me

kill -9 $a

As far as I know, pgrep/pkill come with kill, and should therefore be preferred for something like this. You need to watch out with pkill, though, because it will match a partial name, e.g. use pkill '^program$' instead of pkill program to prevent from killing myprogram, also.

kill $(pidof myprogram)
