Usage: $(basename "$0") [OPTIONS]
Launch an RDP session via xfreerdp. Opens a Zenity GUI prompt if connection
details are not fully provided on the command line.
Options:
--server HOST Hostname or IP (required)
--port PORT RDP port (default: 3389)
--domain DOM Active Directory domain (optional)
--user USER Login username (required)
--pass PASS Password (use - to prompt securely)
--app NAME RemoteApp name (optional — launches app instead of desktop)
--fullscreen Full screen mode (replaces workarea)
--multimon Span across multiple monitors
--drive NAME,PATH Redirect a local folder to the remote session
--sound Enable audio redirection
--gateway HOST Connect through an RD Gateway
--admin Connect to the console/admin session
--no-nla Disable Network Level Authentication
--resolution WxH Fixed resolution (e.g., 1920x1080) instead of dynamic
--profile NAME Load a saved connection profile
--save NAME Save current CLI args as a named profile, then exit
--list List saved profiles and exit
--delete NAME Remove a saved profile and exit
-h, --help Show this help
If --server, --user, and --pass are all provided, connects directly.
Otherwise, opens a Zenity prompt with any provided values pre-filled.
If saved profiles exist, a profile picker is shown before the connection form.
Examples:
# GUI prompt
./$(basename "$0")
# Direct connect
./$(basename "$0") --server 10.0.1.50 --user admin --pass -
# RemoteApp
./$(basename "$0") --server 10.0.1.50 --user admin --pass - --app notepad
# Pre-fill server, prompt for the rest
./$(basename "$0") --server 10.0.1.50
# Save a profile
./$(basename "$0") --server 10.0.1.50 --user pconnor --domain CORP --save work-dc01
# Connect using a profile
./$(basename "$0") --profile work-dc01 --pass -
# List / delete profiles
./$(basename "$0") --list
./$(basename "$0") --delete work-dc01
