From: Torsten Bögershausen <tboegi@xxxxxx> Make it safer to normalize the line endings in a repository: Files that had been commited with CRLF will be commited with LF. (Unless core.autorclf and .gitattributes specify that Git should not do line ending conversions) The old way to normalize a repo was like this: # Make sure that there are not untracked files $ echo "* text=auto" >.gitattributes $ git read-tree --empty $ git add . $ git commit -m "Introduce end-of-line normalization" The new method is one step shorter, more intuitive and does not add untracked files: $ echo "* text=auto" >.gitattributes $ git add --renormalize . $ git commit -m "Introduce end-of-line normalization" Note that "git add --renormalize <pathspec>" is the short form for "git add -u --renormalize <pathspec>".
