I'm going to transfer a private Git repository from win32 box to Ubuntu. Though I can do a final dos2unix commit, but I'd like to rewrite the whole history, so some Git GUI will display log/diff correctly. E.g., gitg will insert empty lines for each CR/LF.
You can use
Here's an example (started in an empty directory with a Unix-type text file:
I strongly recommend doing a full backup beforehand. Running that from your Linux machine (unless you've got a good shell set up in your windows environment) is probably easier.
Edit: had the conversion reversed the first time around.
Mat's answer has nailed the issue right on the head. Unfortunately on Ubuntu Linux, starting with version 10.04 (Lucid Lynx), the dos2unix/unix2dos commands are no longer available, and have been replaced by fromdos/todos. Furthermore, both of the sets of the conversion commands have various degree of ignorance to the existence of binary files, thus if your repository contains images, fonts, etc. they are going to be corrupted by this process.
I was able to find a workaround for the binary file corruption issue that uses Linux 'file' command to correctly identify and process only text files as shown below. The command below uses --tag-name-filter option to preserve the existing tags by moving them to the newly amended commits. Also it uses --force flag to ensure that the command will work in the event you have run tree-filter on your repository before.
