Combined git `continue` command

问题

Variously I might need to run:

• git rebase --continue
• git cherry-pick --continue
• git revert --continue

In each case, my command line is reminding me that I'm mid-(rebase/cp/revert) so it's clear to me that it knows which one is active.

So it feels like there could conceptually be a command git continue which will continue whichever operation is currently active, thus saving some tedious typing?

• A) Does this command exist already (in which case, what is it, and what does it support?
• B) How could I write this command myself, if I were so inclined? (Maybe with aliases?)

回答1:

Such a command does not exist, to my knowledge. However you could create a script for that, called e.g. git-continue:

#!/usr/bin/env bash

repo_path=$(git rev-parse --git-dir 2>/dev/null)

if [ -d "${repo_path}/rebase-merge" ]; then
    git rebase --continue
elif [ -d "${repo_path}/rebase-apply" ]; then
    git rebase --continue
elif [ -f "${repo_path}/MERGE_HEAD" ]; then
    git merge --continue
elif [ -f "${repo_path}/CHERRY_PICK_HEAD" ]; then
    git cherry-pick --continue
elif [ -f "${repo_path}/REVERT_HEAD" ]; then
    git revert --continue
fi

Put the script somewhere in your $PATH, and then you can use git continue.

Note that there are similar flags like --continue, for example --abort, --skip, --quit, which you might want to cover as well.

In addition to @alfunx's answer, I might suggest this change:

Instead of doing repo_path=$(git rev-parse --git-dir 2>/dev/null) so git's return code & log is ignored, I changed the script to this:

#!/usr/bin/env bash

repo_path=$(git rev-parse --git-dir)

if [ $? -ne 0 ]; then
    exit $?
fi

if [ -d "${repo_path}/rebase-merge" ]; then
    git rebase --continue
elif [ -d "${repo_path}/rebase-apply" ]; then
    git rebase --continue
elif [ -f "${repo_path}/MERGE_HEAD" ]; then
    git merge --continue
elif [ -f "${repo_path}/CHERRY_PICK_HEAD" ]; then
    git cherry-pick --continue
elif [ -f "${repo_path}/REVERT_HEAD" ]; then
    git revert --continue
else
    echo "No something in progress?"
fi

Now this script...

1. returns corresponding exit code(for example, 128 for not being a git repository, etc) and error message from git binary itself(like fatal: not a git repository (or any of the parent directories): .git)
2. echo "No something in progress?" if there was nothing going on.
