SEND MULIPLE LINE COMMANDS OVER SSH

Aug 31, 2016 learning SSH

#!/bin/sh
ssh -T usr@host <<'CMDS'
for pid in `ps aux | grep badThings | awk '{print $2}'`
do
  kill -9 $pid
done
CMDS

NOTE The single quotes around the first CMDS prevent the shell to expand variables before sending them to the remote machine. Without it, the dollar sign in the awk command has to be escaped to prevent expansion.

NOTE One cannot specify the remote shell used to execute the multiple line commands sent by ssh. The default shell for the user “usr” will be used.
