一个项目中使用到了多个子模块，切分支的时候每次都要切好几次，使用下面脚本方便批量切分支。

用法

.switch_branch.sh dev
.switch_branch.sh beta
.switch_branch.sh prod

源码

#!/bin/bash

# 函数：获取脚本所在目录的绝对路径
get_script_dir() {
    local SOURCE="${BASH_SOURCE[0]}"
    while [ -h "$SOURCE" ]; do # 解析符号链接
        local DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
        SOURCE="$(readlink "$SOURCE")"
        [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # 如果不是绝对路径，则添加前缀
    done
    echo "$( cd -P "$( dirname "$SOURCE" )" && pwd )"
}

# 函数：检查 git 分支切换是否成功
checkout_branch() {
    local dir=$1
    local branch=$2

    if [ ! -d "$dir" ]; then
        echo "Error: Directory $dir does not exist."
        exit 1
    fi

    cd "$dir" || exit 1

    if ! git checkout "$branch" &> /dev/null; then
        echo "Error: Failed to checkout branch '$branch' in directory '$dir'."
        exit 1
    else
        echo "Switched to branch '$branch' in directory '$dir'."
    fi
}

# 检查是否提供了参数
if [ -z "$1" ]; then
    echo "Usage: $0 <branch-name>"
    exit 1
fi

# 获取分支名参数
BRANCH=$1

# 获取脚本所在目录的绝对路径
SCRIPT_DIR=$(get_script_dir)
echo "Script directory: $SCRIPT_DIR"

# 定义需要切换分支的子模块列表
SUBMODULES=(
    "$SCRIPT_DIR/libs/project1"
    "$SCRIPT_DIR/libs/project2"
    "$SCRIPT_DIR/libs/project3"
    "$SCRIPT_DIR/libs/project4"
)

# 切换主仓库分支
checkout_branch "$SCRIPT_DIR" "$BRANCH"

# 遍历子模块列表并切换分支
for submodule in "${SUBMODULES[@]}"; do
    checkout_branch "$submodule" "$BRANCH"
done

echo "All repositories have been switched to branch '$BRANCH'."
