Hi,

I have a script which I have used for long time, with numerous
git commands and one of commands is this trivial:

git submodule foreach --recursive git clean -ffd

I updated to Git 2.22.0 and noticed Git started to complain:

ˋˋˋ
$ cd /d/boost
$ git submodule foreach --recursive git clean -ffd
Entering 'libs/accumulators'
error: unknown switch `f'
usage: git submodule--helper foreach [--quiet] [--recursive] [--] <command>

    -q, --quiet           Suppress output of entering each submodule command
    --recursive           Recurse into nested submodules

fatal: run_command returned non-zero status while recursing in the
nested submodules of libs/accumulators
ˋˋˋ

Apparently, I have to quote the command to avoid the error

git submodule foreach --recursive 'git clean -ffd'

Is this expected behaviour?
Could anyone help me to understand what has changed?
I can't find any related changes in the release notes.

Best regards,

Probably fixed in https://github.com/gitgitgadget/git/pull/263

Johannes,

Thank you for the pointer.
It does seem related indeed.
