tmsh command to search contents of all Irules for a string

I need to query our F5 Irules for a certain string. Is there an easy way to query all irules across partitions?

 

 

  • Well a script would always be helpful in these cases. There is no one-line command for Irule, so its not doable through command. You can use this below script.

    Create a bash script with below contents.

    #!/bin/bash
    searchword=$1
    RULES="$(tmsh -q -c "cd /; list ltm rule recursive" | grep "ltm rule" | awk '{print $3}')"
    if [ "$RULES" != "" ]; then
            for eachrule in ${RULES}
            do
            result="$(tmsh -q -c "cd /; list ltm rule $eachrule" | grep $searchword)"
                    if [ "$result" != "" ]; then
                    echo "$eachrule"
                    fi
            done
    fi

    Then execute it below format, where Version is your search string.

    bash /var/tmp/find-string-rule.sh Version

    [admin@Lab:Active:Standalone] ~ # bash /var/tmp/find-string-rule.sh Version
    Common/App1-pool_selection-irule
    Common/DDOS-irule
    dummy/test-rule

    As you could see, I got 3 results, 2 rules from Common partition & 1 rule from my dummy partition.

    Hope this helps 🙂

  • Not sure if there's an easy TMSH command for it, but can you run linux commands? I think this one should be pretty close to what you need:

     

    grep -rnw '/config/partitions/' -e 'certainstring'

     

    This searches through all files in the partitions' config for the "certainstring", though if there are a lot of files in the partitions, you may need to expand the filter a bit more.

     

    Based on https://stackoverflow.com/questions/16956810/how-do-i-find-all-files-containing-specific-text-on-linux in case you want to see some more options.
