TMSH CLI to modify objects with keyword variables in them

I am curious if there was a way to modify VIPs w/o specifically defining them within the command .. for example :

 

modify ltm virtual Test-Donkey-HTTPS profiles delete { tcp-600 } profiles add { tcp }

modify ltm virtual Prod-Donkey-HTTPS profiles delete { tcp-600 } profiles add { tcp }

modify ltm virtual Stage-Donkey-HTTPS profiles delete { tcp-600 } profiles add { tcp }

 

So above, I would like to replace all "Donkey" VIPs in one shot to adjust their profiles.

 

Thank you!

    Hi  

    The modify command does not accept the wildcard method. The list command does,

    tmsh list ltm virtual *-Donkey-HTTPS profiles

    But you can still do it this way,

    tmsh modify ltm virtual Test-Donkey-HTTPS Prod-Donkey-HTTPS Stage-Donkey-HTTPS profiles delete { tcp-600 } profiles add { tcp }

    If the list is huge and you want to do with wildcard, you can do it by passing 1 commands output to another,

    1st command: You list all virtuals using wildcard and xargs so you have each virtual space separated.

    tmsh list ltm virtual *Donkey-HTTPS one-line | awk '{print $3}' | xargs

    The output would be,

    Test-Donkey-HTTPS Prod-Donkey-HTTPS Stage-Donkey-HTTPS

    Then you use your modify command on this, so the final command would be,

    tmsh modify ltm virtual `tmsh list ltm virtual *Donkey-HTTPS one-line | awk '{print $3}' | xargs` profiles delete { tcp-600 } profiles add { tcp }

    Note: Be mindful on how you form your regex, do list the virtuals first and then run the modify command while using wildcard.

    Hope this helps.
