Sample .gitattributes file to manage Line Endings for files in project developed in Windows and Linux based OSes

.gitattributes

# 1. Handle line endings automatically for text files
# This ensures LF in the repo, but OS-native endings in the working directory
* text=auto

# 2. Explicitly declare text files (especially your programming language file endings) to be normalized to LF in the repo
*.c       text
*.h       text
*.cpp     text
*.py      text
*.java     text
*.js      text
*.json    text
*.html    text
*.css     text
*.md      text
*.txt     text

# 3. Force LF for specific files (like shell scripts) that MUST be LF on Windows too
*.sh      text eol=lf

# 4. Force CRLF for files that MUST be CRLF (like Windows batch files)
*.bat     text eol=crlf
*.cmd     text eol=crlf

# 5. Denote binary files (prevents Git from touching line endings in images/zips)
*.png     binary
*.jpg     binary
*.jpeg    binary
*.gif     binary
*.pdf     binary
