Remmina command line examples

Edit settings of existing profiles

╭─antenore@bigmom /data/remmina/profiles
╰─$ cp test-spice_spice_ubu20_192-168-1-39.remmina test-spice_spice_ubu20_192-168-1-28.remmina
╭─antenore@bigmom /data/remmina/profiles
╰─$ remmina --set-option server=192.168.1.28 --update-profile test-spice_spice_ubu20_192-168-1-28.remmina
╭─antenore@bigmom /data/remmina/profiles
╰─$ diff test-spice_spice_ubu20_192-168-1-28.remmina test-spice_spice_ubu20_192-168-1-39.remmina
8c8
< server=192.168.1.28
---
> server=192.168.1.39

--set-option can be used multiple times and the last one must be followed by --update-profile and the connection profile file (.remmina)

Encrypt a password

$ echo foopass | remmina --encrypt-password test-spice_spice_ubu20_192-168-1-28.remmina 
Enter the password you want to encrypt:
Encrypted password: G1/IJfT3evw=

Usage:
rdp://username:G1/IJfT3evw=@server
vnc://username:G1/IJfT3evw=@server
vnc://server?VncUsername=user\&VncPassword=G1%2FIJfT3evw%3D

This is the password using the default Remmina password encryption algorithm, but consider that is not safe.

If you want to be safe, use kwallet or gnome-keyring, in the password field use a . (dot) and search how to add secrets from the command line in kwallet or gnome-keyring
