I want code to right click context menu on a file and if it is a .mp4, then convert that to a .mp3 of the same name
also include an option to play faster by +25 +33 +50 or slower by -25 -33 -50 (in a sub menu)
I understand this is different depending on your system, so answer how to do it for the people who use the same system as you
Actually no I don’t.
Linux doesn’t lack GUIs; there’s at least ten entire Desktop Environments in active development at any given time and several of them are quite feature complete such as Cinnamon and KDE. Then you’ve got GNOME which is polished if deliberately feature poor.
A few DEs do have GUI applets for editing the context menu but not all do. Windows doesn’t have one built in. Quote the second page of that thread:
I’m a subscriber to the old adage “GUIs make simple tasks easy, CLIs make complex tasks possible.” This task is either within the city limits of shell scripting or close enough to read the “Speed limit 35 unless posted” sign, so it might as well be left as a “write a config file” type thing.
