Add commit message linter script

[Skfnrj]

What I did

I added a bash script that goes through all commit messages and checks if they meet the requirements.

What it checks

• message length (at least 10 characters)
• presence of one of the required verbs: add, fix, update, remove, improve

How to test

Run the script in the repo and it will print messages that don’t follow the rules.

One suggestion: the check is case-sensitive, so commit messages like "Add feature" or "Fix bug" might not pass. You could consider making the match case-insensitive

Thanks for the suggestion! I updated the script to make the check case-insensitive.

The solution looks good and correctly implements the required checks for commit messages. I like how the script iterates through all commits and validates both length and required verbs.
One small suggestion: the check is case-sensitive, so messages like "Added feature" might not be handled as expected. You could consider making it case-insensitive.

Works well although some commits trigger both cases and are printed on two lines. Might be better to combine the messages and print then on one line when that is the case. Otherwise it doesn't miss any commits that break the rules as far as I can tell.

The script is straightforward and easy to follow. I also like that it checks both the message length and whether one of the required verbs is present.

nice use of piping into a while read
