Exclude file from "git diff"
diff, git, git-diff
Solution
OMG, drivers and AWK to exclude a lousy file? Since Git 1.9 something you can:
git diff -- . ':(exclude)db/irrelevant.php' ':(exclude)db/irrelevant2.php'
(On Windows, replace the single quotes `'` by double quotes `"`.)
Ah, elegance! See the quoted answer and for details this answer by @torek.
Problem
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` with the line `irrelevant.php -diff` and I have also tried creating a file called `.git/info/attributes` containing `db/irrelevant.php`. In all cases, the `db/irrelevant.php` file is included in the diff as a Git binary patch. What I want is for the changes to that file to be ignore by the diff command. What am I doing wrong?
