Git on Windows has some differences compared to Git on Linux due to underlying OS file handling and configuration settings. Here are some key differences and considerations:
### 1. **Line Endings (CRLF vs. LF)**
- **Windows** uses `CRLF` (Carriage Return + Line Feed) line endings, while **Linux** uses `LF` (Line Feed) endings.
- Git can handle these differences with `core.autocrlf`:
- Setting `core.autocrlf` to `true` (recommended for Windows) makes Git convert `LF` to `CRLF` on checkout and back to `LF` on commit.
- On Linux, `core.autocrlf` is typically set to `input` to keep files in `LF` format across platforms.
- **Common Issue**: Line ending inconsistencies can sometimes cause unnecessary changes to files or merge conflicts.
### 2. **Path Length Limitations**
- **Windows** has a maximum path length of 260 characters, which can cause errors when working with deeply nested directories or long file names.
- On **Linux**, path lengths can be much longer, so files that work on Linux may throw errors on Windows.
- **Solution**: You can adjust Windows to allow long paths by enabling the "LongPathsEnabled" registry setting or by using Git’s `core.longpaths` setting:
```powershell
git config --global core.longpaths true
```
### 3. **Case Sensitivity**
- **Linux** is case-sensitive, meaning `file.txt` and `File.txt` are considered different files.
- **Windows** is usually case-insensitive but case-preserving, so `file.txt` and `File.txt` refer to the same file.
- This difference can lead to issues when working with repositories that contain files differing only by case.
### 4. **File Permissions**
- On **Linux**, Git can track executable permissions (`chmod +x`), which is essential for scripts and binaries.
- **Windows** does not natively track file permissions in the same way, so executable flags may not carry over when moving between Windows and Linux.
### 5. **Symbolic Links**
- **Linux** supports symbolic links (`symlinks`), and Git can track these if configured properly.
- **Windows** support for symbolic links is limited and requires elevated privileges or developer mode enabled, so working with repositories containing symlinks can be challenging.
### 6. **Default Shell and Git Bash**
- On Windows, Git often uses **Git Bash** to provide a Unix-like command-line environment.
- Some Linux-specific Git commands or scripts may not work directly in Windows Command Prompt or PowerShell and may require Git Bash or Windows Subsystem for Linux (WSL).
### 7. **Environment Variables and Scripts**
- Some Git hooks and scripts might behave differently due to environment variables or OS-specific commands. Bash scripts used in Linux environments may need adaptation for Windows if run outside Git Bash.
### Best Practices for Cross-Platform Git Repos
To avoid cross-platform issues:
- Standardize line endings with `.gitattributes` (e.g., `* text=auto`).
- Avoid file paths longer than 260 characters.
- Use lowercase consistently for filenames to avoid case sensitivity issues.
- Avoid symlinks if the repository is likely to be used on both Windows and Linux.
