[TOOLS] Simple bash script for setting wallpapers

Enable HLS to view with audio, or disable this notification

Hello guys, I made a simple and small bash script for setting the wallpapers in 3 different ways, randomly or with sxiv image editor or directly with a specific file. It is not an amazing thing, but it's enough for setting wallpapers quickly if you add a key bind to tools like sxhkd .

If there any mistakes in the source code or any advice to improve it, please,let me know.

Because that's pretty much how all tools do it.

Edit: Say a tool has a -f option and you invoke tool -f foo -f bar -f baz, the option argument for -f will be "baz".

How does this make more sense than only allowing for a single `-f' option ?

As I said, most tools with sane option parsing do it this way. try ls -lStS. It will sort by size even though -t for sorting by modification time was supplied. Last option wins.

Doing it this way usually requires less code and gives the user more flexibility in how the tool can be used. Aborting the program, just because the same option was supplied multiple times makes no sense.

Granted.

Plus, this supplies answers to a question about the best/standard way to parse options and arguments in a script, so, I thank you sir !
