Creating a bash script or something to run through several directories

I had a quick question. I have the code below, which as you can see, I am loading in a file. Note that I am in the folder "Angle1" and that I am in the subfolder "1eV"

The code works fine and does what I want it to for this folder. It just prints the number of vacancies to the screen in that file of interest. Is there a way I can loop through with a bash script though? I don't want to manually change "1eV" to "2eV" and so on, up to "150eV"

Also, it would be nice if as it loops though, it writes the number of vacancies to a file, rather than just the terminal. That way, at the end, I'll have a single file in parent directory which has 150 numbers. I can do this manually, it just takes time. I thought I'd check here in case anyone knows how to speed this up for me.

As an extra, I also have to loop all of this through all the Angle folders, which goes Angle1 to Angle24

Thanks!
