Centos Yum update, failure alert – Updated Scripts

This is an update to the blog posted here. The original scripts have an issue when updates are available, in the fact that there is an alert sent if the updates are not installed. Being as the whole point is to check whether updates work, rather than updating; this is unwanted behaviour. So the scripts have been rewritten:

Centos 6:

#!/bin/bash
 /usr/bin/timeout 120 /usr/bin/yum update --assumeno &> /tmp/check-update # check for rpm database & dependency errors 
 rm -rf /tmp/yum_save_tx* # clear yum saved transactions 
 if egrep 'Error:|error:|Another app is currently holding the yum lock|Segmentation fault' /tmp/check-update; then # if condition checks yum output for errors and sends email if there is any
    /bin/mail -s "$(echo -e "Check to see if updates work, failed\nX-Priority: 1")" < /tmp/check-update root 
 fi

Centos 7:

#!/bin/bash
 /bin/timeout 120 /bin/yum update --assumeno &> /tmp/check-update # check for rpm database & dependency errors 
 rm -rf /tmp/yum_save_tx* # clear yum saved transactions 
 if egrep 'Error:| error:|Another app is currently holding the yum lock|Segmentation fault' /tmp/check-update; then # if condition checks yum output for errors and sends email if there is any
    /bin/mail -s "$(echo -e "Check to see if updates work, failed\nX-Priority: 1")" < /tmp/check-update root 
 fi

Thanks Tom.
