How to preserve line endings when extracting git commit messages in a bash script?

I am using git svn to access a SVN server. I am trying to write a script that converts and copy all SVN tags into git tags.

I found this: http://gitready.com/advanced/2009/02/16/convert-git-svn-tag-branches-to-real-tags.html

And this: https://stackoverflow.com/a/3357357/882697

To create that:

git for-each-ref refs/remotes/origin/tags | cut -d / -f 5- |
while read ref
do
    msg=`git log --format=%B -n 1 origin/tags/"$ref"`
    echo $msg
done

The git log command works well in the mingw bash (from git install). But when launching the script from the same mingw bash, the line endings are stripped. I tried to added \r:

msg=`echo $msg | sed 's/\n/\r\n/'`

But it doesn't work either...

Could someone help me please? Thanks!

Solution

  • Try at least putting double-quotes:

    echo "${msg}"

    (see "how do I preserve newlines in a quoted string in bash?")

    That will avoid echo interpreting the output of $msg content (doing field splitting or pathname expansion).
