How to add iRules using CLI

You can automate the irule addition to the Virtual server with the below scripts. Create a file virtual_list and paste all the virtual servers for which you need to add the new irule.

!bin/bash
for i in $(cat virtual_list)
do
rule=`tmsh list ltm virtual $i rules | egrep -v "\{|\}"`
echo "irule is ${rule//[[:blank:]]/} and virtual is $i"
modify ltm virtual $i rules { ${rule//[[:blank:]]/} new-irule-name } 
echo " rule added successfully "
done
