什么是 Windows bash 模拟 Linux sh 文件下载器？

我尝试将 Linux 安装脚本移植到 Windows。在脚本中，我有文件下载，例如

ASL_DISTRO_SITE=surfnet.dl.sourceforge.net
BOOST_NAME=boost_1_44_0
BOOST_VERSION=1.44.0
    if [ ! -e $BOOST_DISTRO_NAME ]; then
        echo_run ${CURL_CMD} http://$ASL_DISTRO_SITE/project/boost/boost/$BOOST_VERSION/$BOOST_DISTRO_NAME -o $BOOST_DISTRO_NAME
    fi

如何将脚本的这部分移植到 windows .bat 语言？默认情况下有来自 MS 的实用程序吗？

I try porting linux setup script to windows. In script I have file download like

ASL_DISTRO_SITE=surfnet.dl.sourceforge.net
BOOST_NAME=boost_1_44_0
BOOST_VERSION=1.44.0
    if [ ! -e $BOOST_DISTRO_NAME ]; then
        echo_run ${CURL_CMD} http://$ASL_DISTRO_SITE/project/boost/boost/$BOOST_VERSION/$BOOST_DISTRO_NAME -o $BOOST_DISTRO_NAME
    fi

How to port such part of script to windows .bat language? Are there any utils coming from MS by default?

您提供的代码中似乎缺少一些项目，但这是如何继续的最佳猜测：

set ASL_DISTRO_SITE=surfnet.dl.sourceforge.net
set BOOST_NAME=boost_1_44_0
set BOOST_VERSION=1.44.0
set BOOST_DISTRO_NAME = xxxx?
set CURL_CMD="c:\program files\curl\curl.exe" ???

cd %BOOST_BASE_DIR%  

if NOT EXISTS %BOOST_DISTRO_NAME% (
    %CURL_CMD% ^
       http://$ASL_DISTRO_SITE/project/boost/boost/%BOOST_VERSION%/%BOOST_DISTRO_NAME% ^
       -o %BOOST_DISTRO_NAME%
)

我没有简单的方法来测试它，所以如果它不起作用，请删除打开和关闭括号和延续字符“^”，并将所有 %CURL_CMD% ... 命令与 if NOT EXISTS ... 放在同一行。

因此，您需要提供 BOOST_BASE_DIR 的值（我已将其作为 var 添加到脚本中）、BOOST_DISTRO_NAME、CURL_CMD ....并且...您需要确定是否需要 echo_run，我不这么认为。对于 echo_run，您必须查看原始脚本。我猜想这是一个定义的函数，并且使用了eval。如果这是真的，上面的方法可能行不通。创建一个不带 IF NOT 测试的 bat 文件，但包含所有 set ... 变量和 %CURL_CMD%，运行该文件，然后添加上面的问题未能解决您的问题;-)

我希望这会有所帮助。

There seem to be a couple of missing items in the code you provide, but here is a best guess of how to proceed:

set ASL_DISTRO_SITE=surfnet.dl.sourceforge.net
set BOOST_NAME=boost_1_44_0
set BOOST_VERSION=1.44.0
set BOOST_DISTRO_NAME = xxxx?
set CURL_CMD="c:\program files\curl\curl.exe" ???

cd %BOOST_BASE_DIR%  

if NOT EXISTS %BOOST_DISTRO_NAME% (
    %CURL_CMD% ^
       http://$ASL_DISTRO_SITE/project/boost/boost/%BOOST_VERSION%/%BOOST_DISTRO_NAME% ^
       -o %BOOST_DISTRO_NAME%
)

I don't have an easy way to test this, so if it doesn't work, remove the open and close parens and the continuation char '^', and put all of the %CURL_CMD% ... command on the same line as the if NOT EXISTS ....

So, you need to provide values for BOOST_BASE_DIR (which I have added as a var to the script), BOOST_DISTRO_NAME, CURL_CMD .... AND ... you need to find out if you need echo_run, I don't think so. For echo_run, you have to look at your original script. I would guess that this is a function defined, and that is uses the eval. If that is true, the above may not work. Make a bat file without the IF NOT test, but with the all the set ... variables, and the %CURL_CMD%, run it and then add the output of the failure to you question above ;-)

I hope this helps.
