The consensus seems to favor:

kill -HUP `ps -ef |grep ( script name) |awk '{print $2 }'`

Although also suggested were the following:


foreach kk (` /bin/ps -ef |  grep  ( script name) |awk '{print $2}'`)
kill -HUP $kk

check out the man page for pgrep / pkill.

what you want is:

  ps -ef |grep ( script name) |awk '{print $2 }' |xargs kill -HUP
There are a lot of ways to do this, some that are most obvious are:

1. kill -HUP `ps -ef |grep (script name) | awk '{print $2 }'`

2. ps -ef |grep (script name) | awk '{print "kill -HUP " $2 }' | sh

3. ps -ef |grep (script name) | awk '{print $2 }' | xargs kill -HUP

pid=`ps -ef |grep ( script name) |awk '{print $2 }'`
kill -HUP $pid
If you're on Solaris 2.8,then you can simply do a
 "kill -HUP `pgrep script_name`" (those are back
ticks, not single quotes, BTW). 

You're using kill wrong.  Kill takes parameters, not input.  ( Good

You want to do:

#>  Kill -9 `ps -ef |grep ( script name) |awk '{print $2 }'`

Note that the outside quotes in that example are backquotes, and the quotes
at the awk are forward, single quotes.
man xargs
Pretty easy, you almost had it.

kill -HUP `ps -ef | grep (script name) | nawk '{print $2}'`
Try this:

ps -ef | grep (script name) | awk '{print $2 }' | xargs kill -HUP

The xargs command usually takes care of these types of situations.
Try back-ticks: 
    kill -HUP `ps -ef | grep $pat | awk '{print $2}'`

To signal all processes owned by a particular user, you might prefer
    kill -HUP `ps -fu userid | awk '{print $2}'`

You can also do it more conservatively, in two steps:
    pids=`ps -ef | grep $pat | awk '{print $2}'`
    echo $pids	# to make sure the list is reasonable
    kill -HUP $pids

However, if you're running a reasonably recent release of Solaris,
"pkill" (/usr/bin/pkill) is a much easier way to do what you want--check
the man pages for pkill and pgrep.  (I believe these commands were
introduced sometime between Solaris 2.6 and 8.)

Try | xargs kill -1   instead of the | kill
