list pools by name

This would give you all the properties for all pools and filter for only the lines that include the pool names and the lines where the string 'user' shows up in the configuration.

From tmsh:

For pools on the default partition (/Common):

list ltm pool all-properties | grep 'ltm pool\|user'

For pools on all other partitions:

list ltm pool /*/* all-properties | grep 'ltm pool\|user'
