Command Line Control
Deep Freeze can be optionally configured and controlled through the command line. Command line
control (dfl) offers network administrators increased flexibility in managing Deep Freeze machines
and works in combination with third-party enterprise management tools. The dfl man page lists the
set of available command line options.
Commands are available to root-privileged users only, unless noted in the table below:

Command Line Examples
1. A sample command using the
boot <frozen>
command is shown below:
sudo dfl -b thawed
In this example, the computer will boot into the Thawed state the next time it is restarted.
2. A sample command using the
freeze <partition>
command is shown below:
