Hi. Creating such a command line utility remains to be done: 
https://www.cendio.com/bugzilla/show_bug.cgi?id=3707

However, it is still possible to do many tasks from the command line if 
you know the correct "charms". Here are some examples:


System Health Check
===================

Check services:

# /etc/init.d/vsmserver status
# /etc/init.d/vsmagent status

User and Group Lookup:

# time getent passwd myuser
# time getent group mygroup


Status
======

Licenses:

# tail /var/log/thinlinc-user-licenses

Load:

UNIX:
# tl-ssh-all "uname -n;uptime;vmstat"
(not exactly the same information though)

Windows:
# tl-best-winserver -v dummy `tl-config /appservergroups/rdp/default/servers`
(repeat for all groups)


List session information:

Sessions on this machine:
# who | grep thinlinc/

Entire cluster, more info:
# tl-ssh-all "uname -n; who | grep thinlinc/"
# tl-ssh-all "uname -n; ps u -C tl-session"

Terminate all sessions for certain user:

# pkill -u someusername tl-xinit

Terminate session with specified number:

# pkill -f 'tl-xinit .*:47'
(where 47 is the session number)


Profiles
========

Names of active profiles:

# tl-config /profiles/order | xargs -n1 | xargs -i tl-config /profiles/{}/name


Locations
=========

All locations:

# tl-config -Ra /printing/nearest/locations

Terminals:

# tl-config -Ra /printing/nearest/terminals


Desktop Customizer
==================

List Application Groups:

# tl-config -Ra /utils/tl-desktop-customizer/groups

Names of Applications Defined Manually:

# grep -h Name= /opt/thinlinc/desktops/xdg_data_dir/applications/thinlinc/*.desktop


Application Servers
===================

UNIX ASGs:

# tl-config -Ra /appservergroups/x11

Windows ASGs:

# tl-config -Ra /appservergroups/rdp
