Monitoring processes. 1

[theSeeker03]

I use ps command to manually make sure that my processes are running. But how can I automate it?

Ideally I'd like to be sent an email, or some other flag, when one of my processes stops running.

There are probably better/other ways, but this is one :

#!/bin/bash
process="MailScanner"
abc=`ps -ef |grep -v grep |grep $process`
if [ "$abc" = "" ]
then
        echo "process $process is not running" | mail -s "Dead Process" foo@bar.org
fi

Note the ` characters in the line containing "ps -ef" are backticks, not quotes ...

$( command ) is preferred to backticks since about 1992 and doesn't need special explanation.

Why is that then ?

It nests more easily, it's more readable, it's been available for 11 years and when you post an example using them you don't have to follow up your own post to point out that they are backticks and not quotes.

#step 0
abc=`ps -ef |grep -v grep |grep $process`
#step 1
abc=$(ps -ef |grep -v grep |grep $process)
#step 2
abc=$(ps -C $process)

look at your manpage, to find out, whether your 'ps' accepts the '-C' parameter.

You should consult a group of patent-lawyers, if you like to use one of the solutions above, because I guess it is a patented routine:
