How to grant Parallel Shell privilege for a user?
Parallel shell by default is disabled for all users except for the admin user created at the time of installation and has to be granted explicitly.
To grant Parallel Shell access to a user, Go to Access Control->User -Action->Servers->Allow Parallel Shell and enable it. After, enabling Parallel Shell, do re-login into the Ezsh shell so that the new settings are loaded.
Note: Make sure to login as the super admin user or the privileged user to grant permission to access the parallel shell.
Note: Every command will work in the parallel shell except the interactive commands like file editor (vi, nano), top, etc.
