show running vs. list commands

I believe F5 created command(

show running-config

) based on cisco device. Don't see any history about this..

I never used the show running-config, so I did some quick tests:

[root@LABBIGIP1:Active:Changes Pending] config  tmsh show running-config > show.txt
[root@LABBIGIP1:Active:Changes Pending] config  tmsh list > list.txt

[root@LABBIGIP1:Active:Changes Pending] config  ll
...
-rw-r--r--.  1 root   root        132912 2017-03-14 13:22 list.txt
...
-rw-r--r--.  1 root   root        132912 2017-03-14 13:21 show.txt

[root@LABBIGIP1:Active:Changes Pending] config  diff list.txt show.txt
[root@LABBIGIP1:Active:Changes Pending] config 

So, both commands are the same. I guess because a lot of people are used to Cisco CLI, F5 just create show running-config as an alias for list command. I am saying that because this command does not follow tmsh rules.

In tmsh commands, list is for listing the configuration, and show is for showing the object status. The following 2 commands provide different things:

[root@LABBIGIP1:Active:Changes Pending] config  tmsh list ltm pool pool_http
ltm pool pool_http {
    members {
        LABServer1:http {
            address 172.16.0.11
            session monitor-enabled
            state up
        }
        LABServer2:http {
            address 172.16.0.12
            session monitor-enabled
            state up
        }
        LABServer3:http {
            address 172.16.0.13
            session monitor-enabled
            state up
        }
    }
    monitor http
}
[root@LABBIGIP1:Active:Changes Pending] config  tmsh show ltm pool pool_http

List is typically "listing" the configured output in bigip.conf. Show results in statistics logged by datasets in MyDB, & TMM.

I typically like to do a lot of

"tmsh show running-config /ltm pool X one-line"

This is awesome when you want to execute quick clones of a configuration. It also has helped me in the past standardize a lot of REST commands, and efficient scripting for certain application builds in automation attempts. That way I can live life a bit more... haha
