Tips for Using BC for Linux
X-window
Beyond Compare for Linux requires X-window. If you attempt to run BC for Linux in a console or SSH terminal without an X-window client, it will not run (including scripts and cron jobs).
Alternate Methods of Registering
To register without running Beyond Compare, save the license key in a text file named BC5Key.txt, BC4Key.txt, or BC3Key.txt depending on your version. 
To register for one user with BC5, use the location:
    ~username/.config/bcompare5/
To register for one user with BC3 or BC4, use the location:
    ~username/.config/bcompare/
To register for all users, use one of the following locations:
    /etc/
    /usr/lib/beyondcompare/
    /usr/lib64/beyondcompare/
Accessing a USB drive or Mounted device
Different Linux distributions can handle this differently. Portable devices will often appear in the /media/ or /mount/ folders. Browse to these locations using the Browse to Folder dialog in Beyond Compare.
Accessing Samba shares
Beyond Compare version 4 or 5
Type the URL of the share into a path edit using the form smb://server/share and press Enter. 
Beyond Compare will prompt you for login information and load the share.
Beyond Compare version 3
The user must mount the location as a folder, then load the folder in Beyond Compare. This mounting process is not done in Beyond Compare, and is specific to your Linux distribution. Here are a few helpful links:
