将系统上所有 git 存储库的远程从 http 更改为 ssh

Question

Recently Github came up with a deprecation notice that the HTTP method of pushing to our repositories is going to expire soon. I've decided to change to the SSH method. On doing that I found that we need to change the remote URL of the repos after setting up keys.

But the change is a tedious process and to do it for all the repositories I have on my local system is quite a lengthy job. Is there some way we can write a Bash script that will go through the directories one by one and then change the remote URL from the HTTP version to the SSH version?

This makes the necessary change from HTTP -> SSH.

git remote set-url origin git@github.com:username/repo-name

The things that we need to change would be the repo-name which can be the same as the directory name.

What I thought about was to run a nested for loop on the parent directory that contains all the git repos. This would be something like:

for DIR in *; do
    for SUBDIR in DIR; do
        ("git remote set-url..."; cd ..;)
    done
done

This will identify all subfolders containing a file or folder named .git , consider it a repo, and run your command.

I strongly recommend you make a backup before running it.

#!/bin/bash

USERNAME="yourusername"

for DIR in $(find . -type d); do

    if [ -d "$DIR/.git" ] || [ -f "$DIR/.git" ]; then

        # Using ( and ) to create a subshell, so the working dir doesn't
        # change in the main script

        # subshell start
        (
            cd "$DIR"
            REMOTE=$(git config --get remote.origin.url)
            REPO=$(basename `git rev-parse --show-toplevel`)

            if [[ "$REMOTE" == "https://github.com/"* ]]; then

                echo "HTTPS repo found ($REPO) $DIR"
                git remote set-url origin git@github.com:$USERNAME/$REPO

                # Check if the conversion worked
                REMOTE=$(git config --get remote.origin.url)
                if [[ "$REMOTE" == "git@github.com:"* ]]; then
                    echo "Repo \"$REPO\" converted successfully!"
                else
                    echo "Failed to convert repo $REPO from HTTPS to SSH"
                fi

            elif [[ "$REMOTE" == "git@github.com:"* ]]; then
                echo "SSH repo - skip ($REPO) $DIR"
            else
                echo "Not Github - skip ($REPO) $DIR"
            fi
        )
        # subshell end

    fi

done
