Cli commad to check history of command

Absolutely! From the tmsh prompt, you can enter either an exclamation point (!) or show /cli history. For example:

(tmos) !
 1  load sys config partitions all base
 2  load sys config partitions all
 3  load sys config partitions all gtm-only
 4  list sys db systemauth.primaryadminuser one-line
 5  show sys software
 6  load sys config partitions all
 7  load sys config partitions all gtm-only
 8  run sys crypto check-cert stdout disabled
 9  save sys config partitions all
10  save sys ucs /var/tmp/Rbbqgcp_80.ucs
11  list sys db systemauth.primaryadminuser one-line
12  load sys config partitions all
13  load sys config partitions all gtm-only
14  delete sys software volume hd1.1
15  delete sys software volume HD1.1
16  list sys software volume

To re-execute a command from history, enter !xx where "xx" is the number of the command shown in history. For example, to re-execute that last "list sys software volume" command:

(tmos) !16
