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

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  nbsp   nbsp   nbsp  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
