Ansible - Command vs Shell

 If you need a shell environment, use the shell module. 

Command:

ansible <host in inventory> -m ansible.builtin.shell -a '<shell command>'

Example

-ansible webservers -m ansible.builtin.shell -a 'mkdir MyTestFolder'

Command Line Tricks for HP Procurve Switchs

Below some helpful commands.

• Display logs or debug on current session:
• terminal monitor (Cisco)
• debug destination session (HP Procurve)
• By default HP Procurve switch don't display packets drops by queue. You can enable the monitoring only on 1 interface with the command below:
• qos watch-queue xx out (where XX is the interface you want to monitor)
• Obtain 'show tech':
• copy command-output "show tech all" sftp user ftpuser 10.10.10.10 show-tech.txt
• Filter a 'show runnning' command:
• Like Cisco, it's possible to use '|' after the 'show running'
