Shell script, for control of a process.

Hello sweetfa2,

Could you explain me a little of your shell script?..

The process is this: /usr/bin/php -q /var/www/AFMNew/serviceFtp.php

Thanks

Hello tel2,

"Only one instance" = Only one process. Means that's not necessary relaunch the process once again...

what issues?, and how do i for avoid that issues?

I'd do it like this

#!/bin/bash
cmd="/usr/bin/php -q /var/www/AFMNnew/serviceFtp.php"

while true
do
  pgrep -f "$cmd" >/dev/null || $cmd
    sleep 60  # Adjust to whatever period you want to check
done

Select allOpen in new window

But since Tintin's script doesn't appear to be designed to be run as a cron job, if it every dies for any reason, then your FTP script no longer has life insurance.

This code would be correct?.

 

#!/bin/bash
cnt=`pgrep $1 | wc -l`
if [ $cnt -eq 0 ]
then
   /usr/bin/php -q /var/www/AFMNnew/serviceFtp.php
fi

Select allOpen in new window

Hello tel2,

I want to check hourly...
