hi !

any idea of what could be wrong with this command line:

kill -9 `ps -ef | grep `who | awk '{print $1}'` | awk '{print $3}'`




root@phoenix User]# kill -9 `ps -ef | grep `who | awk '{print $1}'` | awk '{print $3}'`
Usage: grep [OPTION]... PATTERN [FILE]...
Try `grep --help' for more information.
kill: No such pid who
bash: syntax error near unexpected token `|'
bash: command substitution: line 1: ` | awk '{print $3}''
[root@phoenix User]#
