运行一个输入参数作为DOS批处理脚本命令？ [英] run a input parameter as command in dos batch script?

问题描述

如何我在DOS脚本输入参数运行命令？

How can I run a command in my dos script from an input argument ?

简体脚本bla.bat：结果
＆NBSP; CALL％1

Simplified script bla.bat:
  CALL %1

调用它：结果
bla.bat回声'你好'（或bla.bat混帐地位）

Call it:
bla.bat "echo 'hello'" (or bla.bat "git status")

错误：结果
混帐地位'无法识别为一个内部或外部命令，
可运行的程序或批处理文件。

Error:
'"git status"' is not recognized as an internal or external command, operable program or batch file.

它的工作原理，如果我做CALL git的状态。

It works if I do "CALL git status".

推荐答案

看起来问题可能是你已经围绕在你输入引号，你需要阻止它被分成不同的％N参数，但尝试：

It looks like the problem may be that you have surrounding quotes in your input, which you'll need to stop it being broken into the different %n arguments, but try:

％〜1 将从输入剥离任何引号。

%~1 Which will strip any surrounding quotes from the input.

％〜$ PATH：1 这将剥夺然后任何引号的$ PATH环境-VAR的第一场比赛中进行搜索，然后展开字符串包含完整的路径命令，GIT中使用Windows的发行版，因为Git是一个批处理文件，将不工作，CMD会寻找混帐status.bat

%~$PATH:1 which will strip any surrounding quotes then search within the $PATH env-var for the first match, then expand the string to include the full path to the command, which won't work for git using the windows distro because git is a batch file, and cmd would look for git status.bat

如果其与git的使用，你不妨使用％〜1％和2〜叫混帐然后提供的参数，git的批处理文件，或通过修改$ PATH git.exe直接调用。但请记住，git.bat做一些自己的环境设置调用的git本身之前。

If its to be used with git, you may as well use %~1 and %~2 to call git then provide the argument to the git batch file, or call git.exe directly by modifying your $PATH. But remember that git.bat does some enviroment setup of its own before calling git itself.
