How do I force git to use LF instead of CR+LF under windows?
I want to force git to checkout files under Windows using just LF not CR+LF . I checked the two configuration options but I was not able to find the right combination of settings.
I want it to convert all files to LF and keep the LF on the files.
Remark: I used autocrlf = input but this just repairs the files when you commit them. I want to force it to get them using LF .
Probably I wasn't so clear: the repository is already using LF but the files checked out using msysgit are using CR+LF and I want to force msysgit to get them with LF : forcing Unix line endings .
>git config --list | grep crlf
core.autocrlf=input
The OP added in his question:
the files checked out using msysgit are using CR+LF and I want to forge msysgit to get them with LF
A first simple step would still be in a .gitattributes file:
*.txt -crlf
, to avoid any crlf conversion for files with correct eol.
See Best practices for cross platform git config?
But a second more powerful step involves a gitattribute filter driver and add a smudge step
Whenever you would update your working tree, a script could, only for the files you have specified in the .gitattributes , force the LF eol and any other formatting option you want to enforce.
If the " clear " script doesn't do anything, you will have (after commit) transformed your files, applying exactly the format you need them to follow.
The proper way to get LF endings in Windows is to first set core.autocrlf to false :
git config --global core.autocrlf false
You need to do this if you are using msysgit, because it sets it to true in its system settings.
Now git won't do any line ending normalization. If you want files you check in to be normalized, do this: Set text=auto in your .gitattributes for all files:
* text=auto
And set core.eol to lf :
git config --global core.eol lf
Now you can also switch single repos to crlf (in the working directory!) by running
git config core.eol crlf
After you have done the configuration, you might want git to normalize all the files in the repo. To do this, go to to the root of your repo and run these commands:
git rm --cached -rf .
git diff --cached --name-only -z | xargs -n 50 -0 git add -f
If you now want git to also normalize the files in your working directory, run these commands:
git ls-files -z | xargs -0 rm
git checkout .
I come back to this answer fairly often, though none of these are quite right for me. That said, the right answer for me is a mixture of the others.
What I find works is the following:
git config --global core.eol lf
git config --global core.autocrlf input
For repos that were checked out after those global settings were set, everything will be checked out as whatever it is in the repo – hopefully LF ( n ). Any CRLF will be converted to just LF on checkin.
With an existing repo that you have already checked out – that has the correct line endings in the repo but not your working copy – you can run the following commands to fix it:
git rm -rf --cached .
git reset --hard HEAD
This will delete ( rm ) recursively ( r ) without prompt ( -f ), all files except those that you have edited ( --cached ), from the current directory ( . ). The reset then returns all of those files to a state where they have their true line endings (matching what's in the repo).
If you need to fix the line endings of files in a repo, I recommend grabbing an editor that will let you do that in bulk like IntelliJ or Sublime Text, but I'm sure any good one will likely support this.
