Is it possible to disable a "dangerous" command line option in git?

By habit, I'll often work on a change in my repo, and add/commit it in one shot using git commit -am 'my commit message'

There are times when I only want to add a few of the modified files, so I'll issue preparatory git add commands to meticulously set-up my staging area, and separate the ready-to-commit changes from the half-baked changes.

Then, I'll fat-finger the whole thing by issuing the same git commit -am '...' command as I usually do.

Would there be a way for me to disable the git commit -a option, and/or issue a warning when I use the -a switch? I want to train myself out of this sketchy habit...

This is specific to fish shell, so it won't be useful to everyone... but it might be to some!

function git
  if string match 'commit' $argv[1] > /dev/null
    set has_am 0

    for arg in $argv
      if string match -r -- '^-am.*' $arg > /dev/null
        set has_am 1
      end
    end

    if test $has_am -eq 1
      echo -e "Commit All detected.\nDon't do this!"
    else
      command git $argv
    end
  else
    command git $argv
  end
end

I don't know of a git config setting which would prevent/disallow the --all/-a option of a git commit.

You could consider though a:

(-q for 'quiet')

That would remove from the working tree any of your modification (except the ones already added to the index)

  • post-commit hook

    if [[ "$(git stash list|| grep "stash@{0}" | grep "possible commit am")" != "" ]]; then
  git stash pop -q
fi

That should allow you to type a git commit -[a]m "a commit message" without committing everything.
And if you want to skip those hooks for one commit:

git commit --no-verify -m "a commit message"

Create a wrapper script named git that will catch bad commands and forward good ones on to the real git. Put it earlier in your $PATH:

#!/bin/bash

for ARG in "${@}"; do
    if [ "${ARG}" = "-am" ]; then
        echo "Hey! Don’t do that!" 1>&2
        exit 1
    fi
done

exec /usr/bin/git "${@}"

Almost all git commands will work just fine:

$ git pull
remote: Counting objects: 1183, done.
remote: Compressing objects: 100% (728/728), done.
remote: Total 1183 (delta 771), reused 632 (delta 455)
Receiving objects: 100% (1183/1183), 1.12 MiB | 1.46 MiB/s, done.
...

But the ones you don’t want to work won’t:

$ git commit -am "foo"
Hey! Don’t do that!
