There's a `docker sandbox run gemini` command, but it requires Docker Desktop to be installed, which is pretty undesirable on Linux since it replaces Docker Engine with a VM environment. This simple script does similar things.
#!/usr/bin/env bash
set -e
image='docker-gemini'
case "$1" in
-h|--help)
echo 'Usage: docker-gemini [options] [command] [prompt]'
echo 'docker-gemini commands:'

Removes any local branches except for main/master and pulls the latest changes from the origin. It's helpful to run once a feature has been merged
#!/usr/bin/env sh
set -e
master_names='main|master'
branch_regexp='s/[^A-Za-z0-9_\/-]*//g'
master_branch="$(git branch | grep -E "${master_names}" | sed "${branch_regexp}" | head -n 1)"
branches="$(git branch | grep -v -E "${master_names}" | sed "${branch_regexp}")"
