diff returning entire file for identical files
I’ve got a website that has a git repo. I cloned the repo so that I could develop in one directory and then push to the repo, and then pull in the live/prod directory (would be interested in suggestions for a better way to do this if there is one, but that’s outside the scope of this question).
I did the following in the live directory to push all my latest changes:
git add . git commit -a // added a message git push
I then did the following in the dev directory:
git clone email@example.com:user/repo.git
I then opened two files, prod/root/test.php and dev/root/test.php, and they looked identical. However, when I did the following diff command, it outputted the entire file:
diff prod/root/test.php dev/root/test.php
I am so confused as to why diff would output the entire file if they’re identical… I also tried googling this and can’t find anyone else with this problem. Maybe it’s a line endings issue or a character encoding issue where they look the same but they are actually different and git/bitbucket converts it when you push to their repo? That’s the only thing I can think of… Either that or I’m missing something really obvious.
Here’s the output:
1,3c1,3 < <? < echo '<p>Hello world!</p>'; < ?> --- > <? > echo '<p>Hello world!</p>'; > ?>

This seems like a whitespace issue, in order to avoid them in the future, you can setup Git to normalize them.
Windows and UNIX system don’t use same line-ending, to prevent conflict from happening based on these, you should setup you git config this way:
- Windows :
git config --global core.autocrlf true
- Unix :
git config --global core.autocrlf input
Next, to make sure we only commit with ideal whitespace rules, you can set this config option:
git config --global core.whitespace trailing-space,space-before-tab,indent-with-non-tab
Most likely it’s line termination. Try
git diff --ignore-space-at-eol. And for plain (not
git) diff it’s
That usually means the line endings are different. Most diffin programs allow you to ignore differences in line endings. Does yours allow you to do so?
