Within Filebrowser you can toggle the shell (< > icon at the top right) and this will open a shell command window at the bottom of the screen.
By default no commands are availabe as the command list is empty
To enable commands these need to either be done on a per-user basis (including for the Admin user).
You can do this by adding them in Settings > User Management > (edit user) > Commands or to apply to all new users created from that point forward they can be set in Settings > Global Settings

{% hint style="info" %} If using Docker and you want to add a new command that is not in the base image then you will need to build a custom Docker image using `filebrowser/filebrowser' as a base image. For example to add 7z:
FROM filebrowser/filebrowser
RUN sudo apt install p7zip-full
