Gaia: how to cron binaries depending on shared libraries

I have recently came across an issue that scheduling custom scripts with cron may not work properly on Gaia for binaries that require shared libraries to run.

For example, sendmail uses libProdUtils.so and requires access to this lib file when scripted. Path is defined for your bash shell, but not for cron. So if you make a simple script like this one:

#!/bin/bash 
/opt/CPsuite-R77/fw1/bin/sendmail -t 1.1.1.1 -m /var/tmp/testmail.txt

to send an email on a particular even, it works perfectly from bash CLI but fails when running through cron job.

To fix it, you need the script to call shell parameters explicitly. To do it, add source /etc/bashrc before executing any other command:

#!/bin/bash 

source /etc/bashrc
/opt/CPsuite-R77/fw1/bin/sendmail -t 1.1.1.1 -m /var/tmp/testmail.txt

By the way, Check Point own sendmail sucks big time and can only run when using message file and not as just a CLI command, even with 100% correct syntax. But this is something for another post.
