I am working with the git filter branch for one specific task. It is using the sed command. When I use simple regex everything is working but for something more complex it is not. Maybe I have mistake in the regex or in the escaping chars. Please help.

git filter-branch -f --msg-filter 'sed -e "s/\[PEM-2233\] Merge branch 'master' of https:\/\/bitbucket\.test\.domain\.com\/rrr\/pem\/hello-world into feature\/PEM-2233-do-acceptance-tests/CHANGED/"' -- --all

The commit message I am trying to catch is

[PEM-2233] Merge branch 'master' of https://bitbucket.test.domain.com/rrr/pem/hello-world into feature/PEM-2233-do-acceptance-tests
  • change sed subcommand separator to # Nov 1 '17 at 8:49
  • not so pro at it, what is the command for changing? or just sed -e "s#regex#replacement#g"

The issue are the single quotes around 'master'. The first of these quotes will end the single quoted string that starts with sed -e. The quotes themselves will not be passed on to sed.

It's equivalent to the issue with

$ echo '"hello 'user'"'
"hello user"

Change the quoting to

  • '\'master\'' (the string 'master' will be seen as an unquoted string by the shell), or
  • '"'master'"' (the string 'master' will be seen as a double quoted string by the shell).

Also, to avoid the leaning toothpick-syndrome, use another delimiter for the s command:


You can't nest single quotes. The single quote before master closes the quoted string starting after --msg-filter.

As you can't include single quotes in a single quoted string, you need to end the string and properly escape the quotes:

branch '\'master\'' of http
