Add *.sh text eol=lf to .gitattributes to enforce LF for shell scripts.

01Command

Command

$ git config core.autocrlf input  # plus .gitattributes

02What it does

Line-ending drift causes noisy diffs and broken scripts; committing a .gitattributes file applies rules consistently for every clone, unlike local core.autocrlf settings that differ per machine. It is configuration as code.
