Windows 如何获取参数列表？
我想找到一个与Bash的Windows 如何获取参数列表？,windows,batch-file,Windows,Batch File,我想找到一个与Bash的$@相对应的Windows批处理，它包含传递到脚本中的所有参数的列表 或者我不得不为shift？%*似乎保存了传递给脚本的所有参数。对了，%*用于所有命令行参数（不包括脚本名称本身）。您还可能会发现以下内容很有用： %0-用于调用批处理文件的命令（可以是foo，。\foo，c:\bats\foo.bat等） %1是第一个命令行参数， %2是第二个命令行参数， 依此类推，直到%9（9号之后的可以使用SHIFT） %~nx0-批处理文件的实际名称，与调用方法无关（some b
$@或者我不得不为
shift%*%*%0foo。\fooc:\bats\foo.bat%1%2依此类推，直到
%9SHIFT%~nx0%~dp0%~dpnx0更多信息示例位于和
%1%*因此，用正常的语句来处理这样的事情是不可能的
myBatch.bat "&"^&
“&”&@echo off
SETLOCAL DisableDelayedExpansion
SETLOCAL
for %%a in (1) do (
set "prompt=$_"
echo on
for %%b in (1) do rem * #%1#
@echo off
) > param.txt
ENDLOCAL
for /F "delims=" %%L in (param.txt) do (
set "param1=%%L"
)
SETLOCAL EnableDelayedExpansion
set "param1=!param1:*#=!"
set "param1=!param1:~0,-2!"
echo %%1 is '!param1!'
echo onrem%1但是为了能够在上重定向
echo的输出，您需要两个FOR-loop
额外的字符*#
用于防止类似/？
的内容（将显示REM的帮助）。
或者，行末端的插入符号可以用作多行字符
FOR/F应在延迟扩展关闭的情况下工作，否则带有“！”的内容将被销毁。
在删除param1
中的额外字符后，您得到了它
要安全地使用param1
，请启用延迟扩展
编辑：对%0添加一条备注
%0
包含用于调用批处理的命令，还保留了类似于FoO.BaT
但是在调用函数后，%0
以及在%0
中包含函数名（或者更好的是用于调用函数的字符串）。
但是使用%~f0
您仍然可以回忆起文件名
@echo off
echo main %0, %~0, %~f0
call :myLabel+xyz
exit /b
:MYlabel
echo func %0, %~0, %~f0
exit /b
输出
main test.bat, test.bat, C:\temp\test.bat
func :myLabel+xyz, :myLabel+xyz, C:\temp\test.bat
我发现下次当你需要查找这些信息时。您可以在cmd中键入call/？
，而不是打开浏览器并用谷歌搜索它，您将得到：
...
%* in a batch script refers to all the arguments (e.g. %1 %2 %3
%4 %5 ...)
Substitution of batch parameters (%n) has been enhanced. You can
now use the following optional syntax:
%~1 - expands %1 removing any surrounding quotes (")
%~f1 - expands %1 to a fully qualified path name
%~d1 - expands %1 to a drive letter only
%~p1 - expands %1 to a path only
%~n1 - expands %1 to a file name only
%~x1 - expands %1 to a file extension only
%~s1 - expanded path contains short names only
%~a1 - expands %1 to file attributes
%~t1 - expands %1 to date/time of file
%~z1 - expands %1 to size of file
%~$PATH:1 - searches the directories listed in the PATH
environment variable and expands %1 to the fully
qualified name of the first one found. If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string
The modifiers can be combined to get compound results:
%~dp1 - expands %1 to a drive letter and path only
%~nx1 - expands %1 to a file name and extension only
%~dp$PATH:1 - searches the directories listed in the PATH
environment variable for %1 and expands to the
drive letter and path of the first one found.
%~ftza1 - expands %1 to a DIR like output line
In the above examples %1 and PATH can be replaced by other
valid values. The %~ syntax is terminated by a valid argument
number. The %~ modifiers may not be used with %*
在脚本中检索所有参数的方法如下：
@ECHO off
ECHO The %~nx0 script args are...
for %%I IN (%*) DO ECHO %%I
pause
下面是一种获取参数并将其设置为env vars的相当简单的方法。在本例中，我将它们称为键和值
将下面的代码示例保存为“args.bat”。然后调用批处理文件
您是从命令行保存的。
示例：arg.bat--x90--y120
我提供了一些echo命令来帮助您完成这个过程。但是
最终的结果是--x的值为90，--y的值为120（如果按照上面指定的方式运行示例；-）
然后可以使用“if defined”条件语句来确定是否运行代码块。
让我们说跑步：
“arg.bat--x hello world”
然后我可以使用语句“IF DEFINED--x echo%--x%”，结果将是“helloworld”。如果您运行批处理，它应该更有意义
