Use bitwarden rbw as git-credential helper

git-credential-rbw

#!/usr/bin/env bash

# rbw git-credential helper
# Based on https://github.com/lastpass/lastpass-cli/blob/master/contrib/examples/git-credential-lastpass

# A credential helper for git to retrieve usernames and passwords from rbw.
# For general usage, see https://git-scm.com/docs/gitcredentials.
# Here's a quick version:
# 1. Put this somewhere in your path.
# 2. git config --global credential.helper rbw

For macOS users, due to the bash version in macOS is still 3.2(at least before Ventura 13.2.1) and not supported declare -A command. A workaround for this is follow the steps above: Install a newer bash via homebrew or anything else and then change shebang to #!/usr/bin/env bash

Ahh yes, good call. When I was using a mac, I got around this issue by installing the latest bash version from homebrew.
