fix_git_crlf-lf.sh

#!/bin/bash

# Purpose of this bash script: Force git to change line endings to LF
# When this problem occurs: When code is contributed cross-platform and/or when not all Windows contributers have correct git config core.autocrlf settings
# IMPORTANT: after force-fixing the line endings, create a .gitattributes file in the repo. This ensures line endings consistency in the future.
# How to use this script: create a fixle.sh file, paste this in and run it with bash (Window's git bash, WSL's bash, or Mac/Unix's bash).

#Set LF as your line ending default.

#Set autocrlf to false to stop converting between windows style (CRLF) and Unix style (LF)

#Add all your changed files back, and prepare them for a commit. This is your chance to inspect which files, if any, were unchanged.

# It is perfectly safe to see a lot of messages here that read
