Want to exclude file from “git diff”

Question

I am trying to exclude a file (db/irrelevant.php) from a Git diff. I have tried putting a file in the db subdirectory called .gitattributes

Answer 1

similar to Ben Roux's solution, but sharing anyway:

git status --porcelain | grep -v $PATTERN_TO_EXCLUDE | awk '{print $2}' | xargs git diff

or, if the changes have already be committed locally:

git diff --name-only origin/master | grep -v $PATTERN_TO_EXCLUDE | xargs git diff origin/master

Examples:

git status --porcelain | grep -v docs | awk '{print $2}' | xargs git diff origin/master

git diff --name-only origin/master | grep -v docs | xargs git diff origin/master
