I guess you are missing a after pool keyword, use the command like this
check if small a or capital A after pool keyowrd will work.
tmsh
list gtm pool a all load-balancing-mode
tmsh show gtm wideip a all detail | grep 'WideIp\|Destination'
The following command will find pools with a return to DNS option and print the name of the pools.
tmsh -c 'cd /; list gtm pool recursive all-properties one-line' | awk '/return-to-dns/{print $4}'
My Other GTM master Commands which i use frequently and keep customizing them based on the requirement and then pul them in excel sheet and then use DATA TAB, and there is one option text to columns
And use Delimited radio button and run the Wizard to convert F5 Command output text command output to mulitple colums for easy readability.
My Other GTM master Commands you can try to get more results of your choice
