Are CRLF lines ok in a Rails project deployed on Linux?

Question

I have a Git repository (originally CVS, then SVN, now Git) containing a Rails project that has been deployed on Linux for a while now. Everything seems to run fine.

Answer 1

A comment to davitenio's answer and Daniel Beardsley's comment; I believe you could use this little program as a wrapper around dos2unix:

#!/bin/sh
for f in $@; do
    if [ $(file -b -n -i -m /dev/null $f | grep -c "text") -gt 0 ]; then
        dos2unix $f
    fi
done

although there is probably still some corner case that will fail.

Answer 2

If it is ok for you to rewrite your repository's history (see problems with rewriting history) you could use git filter-branch to convert CRLF to LF:

git filter-branch --tree-filter 'find . -path './.git' -prune -o -type f -exec dos2unix \{} \;' HEAD

Note that if you have binary files in your repository you will have to refine the find command to exclude them.
