Bash script to extract filenames from git whatchanged

I’m trying to get a list of all the js files that changed to know what to reminify.

I previously asked this question

  • quitting git log from a bash script
  • git post-commit hook - script on committed files
  • Parse git log file names to json
  • fatal: Authentication failed Git Bash
  • Append git's branch name to command prompt
  • Bash: How to compose functions where the inner function will return an argument
  • So far this is the best I came up with but it feels really unsafe.

    GITCHANGES=$(git whatchanged -n 1 --pretty=format:)
    I=0;
    for f in $GITCHANGES;
    do
        I=$(($I + 1));
        if [[ $(($I % 6 )) == 0 ]]; then
            echo "$f"
        fi
    done
    

    But this gives me all the files that changed (php css js) and not just the js files

    How would I get just the js files? Also is there a better way to accomplish this?

    From this answer, use git show --pretty="format:" --name-only HEAD^ to get a list of changed files. Then pipe it through grep.

    git show --pretty="format:" --name-only HEAD^ | grep '\.js$'
    

    Your script can be condensed really simply into

    git diff-tree --name-only HEAD^ HEAD | grep '\.js$'
    

    This will spit out a list of all .js files that differ between HEAD^ (first parent) and HEAD.
