A git pre-commit hook to check the year of copyright notices

Like every year, touching a source file means you also need to update the year of the copyright notice you should have at the top of the file. I always end up forgetting about them, this is where a git pre-commit hook would be ultra-useful, so I wrote one:# # Check if copyright statements include the current year # files=`git diff --cached --name-only` year=`date +"%Y"` for f in $files; do head -10 $f | grep -i copyright 2>&1 1>/dev/null || continue if ! grep -i -e "copyright.*$year" $f 2>&1 1>/dev/null; then missing_copyright_files="$missing_copyright_files $f" fi done if [ -n "$missing_copyright_files" ]; then echo "$year is missing in the copyright notice of the following files:" for f in $missing_copyright_files; do echo " $f" done exit 1 fiHope this helps!
