Run this in your local Git repo to convert it from CRLF to LF ending, and make sure it *stay so*.

crlf_to_lf.sh

#!/bin/bash
git config --global core.eol lf
git config --global core.autocrlf input

echo "* text=auto eol=lf" > .gitattributes

# Find files but exclude .git directory
find . -type f ! -path '*/.git/*' | while read -r file; do
    # Check if the file is a text file
    if file "$file" | grep -q text; then
        sed -i 's/\r$//' "$file"
    fi
done

Instructions

• place the script in the root of your Git repository.
• chmod +x crlf_to_lf.sh
• ./crlf_to_lf.sh.

How it works

• Global Git Configuration: Sets Git to handle line endings consistently, using LF (Line Feed) for checkouts and commits.
• Creates or updates a .gitattributes file in the repository, enforcing the use of LF line endings for all text files.
• Recursively changes existing CRLF (Carriage Return + Line Feed) endings to LF across the repository, while carefully excluding the .git directory to prevent corruption of Git's internal files.
