I only use the terminal to resolve issues. This was more often at the start, when I just swifted from windows but now I rarely use it.
That said, I have no idea what I’m doing. I only copy paste commands that I find online or what they tell me to use in the forum/discord
I use Mint





Not sure if this helps, but don’t you need to right click and under permission allow it to run as a program?
Then I can often just double click and run
