Shell script - timeout command

salmonbaytech

any thoughts on a tool that is already installed on pfsense that will do the same thing as the timeout command?
http://www.gnu.org/software/coreutils/manual/html_node/timeout-invocation.html

I have a shell script, that I would like to timeout as a backup to it already exiting on its own.

made an SH script to accomplish what I needed. thought I would share it.


#! /bin/sh

timeout=$1
sleeptime=$2
command=$3

# test pid is still around
PIDActive() {
	pid=$1

	test=`ps -p $pid | grep $pid`
	if [ -z "$test" ]; then
		return 1
	fi
	return 0
}

# run command & capture pid
$command&
commandpid=$! 

# What happens first? pid exits or timeout
counter=0
while PIDActive $commandpid && [ "$counter" -le "$timeout" ]; do
    sleep $sleeptime
    counter=`expr $counter + $sleeptime`
done

# if we get to this point and the pid is still active, kill it
PIDActive $commandpid && kill -s KILL  $commandpid
