#3 : Clean Ignored Files in Git Repos
This script removes ignored files from Git repositories using git clean -Xdf.
Added Comments in code to explain the same

hi @piyushkumar079, clean implementation! can you briefly explain what your code does?

[rootCircle]

also, you can print a helpful message if current working directory is not a git directory rather than Finished cleaning ignored files in Git repositories.

ping me here when you're done with those, so we can move forward with your PR!

@rootCircle
explanation
git_repos=$(find . -name .git -type d -prune)
this line finds the ./git folder
cd ..
this is done since .gitignore file lives outside of ./git folder
git clean -Xdf
with -Xdf flag this line forcefull deletes the files mentioned inside the .gitignore file
cd -
this takes us back to the previous directory (like in back in a browser)
>/dev/null 2>&1
this is a popular method that supresses error messages

Changes
made the recommeded change
-z flag checks if the array is empty

explanation
git_repos=$(find . -name .git -type d -prune)
this line finds the ./git folder

In the comment in code you wrote and I quote # Loop through each Git repository, what do you mean by that, there can be one and only more .git in CWD or am I mistaken somewhere?

yes as quoted from the moderator
To find list of all git repos inside current directory you can use: "find . -name .git -type d -prune"
it starts searching from the current directory (represented by the dot, ".") and descends into all subdirectories.
a example would be if a project has both frontend and backend in a single directory and both the directories are tracked by git independently. and if the script is run on the root of both the directories it will actually find both the .git directory and then clean .gitignore by looping thru each repo
