How to kill some runnin perl script from bash script?

postcd · 04-23-2014, 05:38 AM

aim is to kill this script after 120 seconds of running and saving its output to a file. but my command not working and appears not killing the process.

Code:

#!/bin/sh
set -ex

while read domain;do
output=$(/root/tra*/script.pl $domain & pid=$!
sleep 120
pkill -f $domain)
echo "something"
echo "$output" > $domain_outputfile.txt
cat $domain_outputfile.txt
done < domains.txt

any idea why the command is not killed?

Maybe start with a simple version then slowly add to it, this works:

Code:

#!/bin/bash

output=$( ping localhost &
sleep 20
pkill -f ping )

echo "[*] output: $output"

So try just doing the middle bit then adding the extras slowly, it may be that the while loop is the culprit.

It it's the ONLY script running under perl, how about "killall /usr/bin/perl"? I have a python script that sometimes starts 50 threads and this technique works like a champ on it. In fact, if others on the system are running their own python scripts it leaves them alone since I'm not running as root so it only kills my processes.

On the other hand if you have to, you could do something like this to get the process pid and then kill it
