N/A

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Bash, CMD

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

git submodule foreach --recursive git clean -dxff

• What did you expect to occur after running these commands?

Proper running of the git clean -dxff command for each submodule

• What actually happened instead?

Error message

$ git submodule foreach --recursive git clean -dxff
Entering 'src/lib/opennurbs'
error: unknown switch `d'
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 src/lib/opennurbs
.

• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?

Happens with all repositories tested.

• Additional note

The command works with the form git submodule foreach --recursive "git clean -dxff", but that seems to be an undocumented change from git version 2.21.0.windows.1, where the form git submodule foreach --recursive git clean -dxff still worked as expected.

It seems this was caused in upstream git in commit a282f5a. A fix seems to be in the in the making.

[dscho]

It entered next already as git@30db18b, which means that it is on track to be included in the next major version of Git.

@jesterKing feel free to install Git for Windows' SDK, then build an initial Git with sdk build git, then sdk cd git and cherry-pick this fix, then test, and open a PR.

(If this is too dense an explanation how to continue, please do not hesitate to ask for help.)

[rimrul]

The fix made it into git v2.22.1 and newer, so I'll assume this is working now.
