There are a handful on non-default apps I’ve used across my last 3-4 distros at least:
-
mpv - the best video player, period. Minimalist UI, maximalist configuration options. I’ve been using it for many years across many OSes and at this point everything else feels wrong.
-
Geany - My favorite GUI text editor on Linux.
-
Foliate - the simplest eBook reader I’ve found.
-
Strawberry - It’s “fine”. Honestly, I’ve never found a music player on Linux that I really liked. I keep falling back to Strawberry because it’s familiar and generally works as expected.
There’s a separate command called
visudo
for this purpose.You CAN use any ol’ text editor but visudo has built-in validation specific to the sudoers file. This is helpful because sudoers syntax is unique and arcane, and errors are potentially quite harmful.
