Export specific Git commits as patches

Question

I am trying to export several commits (those that contain a specific ticket number 1234 in the commit message) to patch files. EDIT The working script is on https://github.com/amenk/SelfScripts/blob/master/git-extract-patches This is what I have ``` #!/bin/bash -x commits=`git log --pretty=oneline | grep "#1234" | cut -f1 -d" "` no=1; for COMMIT in $commits do git format-patch -1 $COMMIT --start-number=$no no=$(($no+1)) done ``` But for some reason executing of git format-patch fails: ``` $ ./getpatches.sh ++ git log --pretty=oneline ++ grep '#6809' ++ cut -f1 '-d ' + commits='da591d66f05513488ee06857edc9d24a046c179d 4fd781da9cc503b961f8e4c42bbb136d9e3c1806 3a9311f5507f91f830b44673c57f672e7aabaac0' + no=1 + for COMMIT in '$commits' + git format-patch -1 'da591d66f05513488ee06857edc9d24a046c179d' --start-number=1 fatal: ambiguous argument 'da591d66f05513488ee06857edc9d24a046c179d': unknown revision or path not in the working tree.

My git was implicitly using the `--color` option so the `$COMMIT` string contained some color codes. So this messed up the parsing. Interesting, that also the color was contained in my error messages.

But you do not see this in the terminal (it's just colorful), and also not after pasting to stack overflow.

The solution is:

```
commits=`git log --no-color --pretty=oneline | grep "#1234" | cut -f1 -d" "`
```
