Another question!!!

I´m doing s squid check procees script.... Works very well but in some cases fail.... because i check if the squid.pid file still exist in /var/run...

Yesterday squid procees died but squid.pid continued in /var/run... for these reason my script can´t detect that squid was die...

here is my actual script:

Código: Selecionar todos

#!/bin/sh
#
DEBUG=0

# argentobr variables
. /argentobr/variables.conf
. /argentobr/mailsend.conf
if [ -n "`ls /var/run/squid.pid`" ] ; then
               echo "squid esta funcionando"
               
            else
               echo "squid no esta funcionando"
               /argentobr/squidstart
               /argentobr/mailsend -d $host -smtp $smtp -t $para -f $de -sub "$asunto" < $mensaje

               
            fi

echo ""

I know if i use squid -k check command it will return to me a message... How can i do a script that returns to me a variable with 0 or 1.... 0 for squid is running... 1 for squid stop...

Regards...

[Claudio]

Try something like this:

if [ -n "`ps | grep squid`" ] ; then .....

ps = list running process
grep = search for the string squid
-n = return true if the argument is not empty

Thank you very much claudio... I will try...

Sorry Claudio your idea don´t work well..

But i fix it.....

I use the $ variable... i put something like this:

squid -k check
if [ $ = 0 ] ; then
