Windows下Git Bash脚本带指定Profile启动Chrome.exe的问题

问题背景 #

需要在Windows的Git Bash中通过Shell脚本启动Chrome，同时指定特定配置文件和目标URL，且不想将chrome.exe加入系统PATH。目前不带Profile参数时脚本可正常运行，但添加参数后Chrome会使用默认配置文件，还会错误解析URL，尝试多种转义方式均无效。

错误脚本示例 #

echo ----------------------------------------

function openSomeUrl() {
        local URL="https://github.com/chipbite/"
    # some url
    local BROWSER='/c/Program Files (x86)/Google/Chrome/Application/chrome.exe'

    echo "$BROWSER" "$URL"

    # so for some URLs, I want a private profile, for others my work profile
    # I have without success tried e g 
    # (1) adding the switches separately (ie $BROWSER $SWITCHES $URL), 
    # (2) to the BROWSER variable/command and 
    # (3) as a part of/prefix to the $URL variable, as below, here:

    if ( echo $URL | grep -q chipbite ); then
      URL="--profile-directory='Profile 1' $URL" 
    else
      # URL="--profile-directory='Default' $URL"  
      echo default
    fi
 
    echo "$BROWSER" $URL # 1 - without quotes
    # "$BROWSER" $URL  
            # --> /c/Program Files (x86)/Google/Chrome/Application/chrome.exe --profile-directory='Profile 1' https://github.com/chipbite/
            # opens in default profile, tries url-> 1' -- as in the end of 'Profile 1'

    echo "$BROWSER" "$URL" # 2 - with quotes. prints exactly same as 1, but that is since they are not escaped.
    "$BROWSER" $URL
}

openSomeUrl

echo ----------------------------------------

问题原因 #

核心是参数传递的引号处理错误：把配置参数和URL拼到同一个变量里，且用了Git Bash风格的单引号，而Windows程序（Chrome）不识别这种单引号，导致Chrome把'Profile 1'里的单引号当成参数的一部分，无法正确识别配置目录，还错误地把1'解析为URL的一部分。

正确解决方案 #

方案1：拆分参数单独传递 #

将配置参数单独存储，调用时分别传递给Chrome，确保带空格的参数被正确包裹：

echo ----------------------------------------

function openSomeUrl() {
    local URL="https://github.com/chipbite/"
    local BROWSER='/c/Program Files (x86)/Google/Chrome/Application/chrome.exe'
    local PROFILE_SWITCH=""

    echo "$BROWSER" "$URL"

    if echo "$URL" | grep -q chipbite; then
      # 去掉单引号，直接用空格分隔参数内容
      PROFILE_SWITCH="--profile-directory=Profile 1"
    else
      PROFILE_SWITCH="--profile-directory=Default"
      echo default
    fi
 
    # 关键：分别传递浏览器路径、配置参数、URL，每个带空格的参数用双引号包裹
    "$BROWSER" "$PROFILE_SWITCH" "$URL"
}

openSomeUrl

echo ----------------------------------------

方案2：使用Windows的start命令 #

如果直接调用仍有问题，可适配Windows原生的start命令，确保参数被正确解析：

echo ----------------------------------------

function openSomeUrl() {
    local URL="https://github.com/chipbite/"
    # 也可以用Git Bash风格路径：'/c/Program Files (x86)/Google/Chrome/Application/chrome.exe'
    local BROWSER="C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
    local PROFILE_SWITCH=""

    if echo "$URL" | grep -q chipbite; then
      PROFILE_SWITCH="--profile-directory=Profile 1"
    else
      PROFILE_SWITCH="--profile-directory=Default"
      echo default
    fi
 
    # start命令第一个参数为窗口标题，留空即可；所有带空格的内容用双引号包裹
    start "" "$BROWSER" "$PROFILE_SWITCH" "$URL"
}

openSomeUrl

echo ----------------------------------------
