在命令行处理分号 [英] Processing Semicolon on Command line

问题描述

我用来运行大型C + _ +构建两个批处理文件，第一个启动的过程，创建目录，并找出发送给第二个脚本是什么。如果某些信息是psented的第一个脚本$ P $，我有一个弹出一个窗口，要求输入密码的程序。这是通过调用这样所述第二脚本传递到第二脚本

I have two batch files which is used to run a large c+_+ build, the first one starts the processes, creating directories and figuring out what to send to the second script. If certain information is presented to the first script, I have a routine that pops up a window and asks for a password. This is passed to the second script by calling the second script like this

call script2.bat -pw:myPassword

，其中MYPASSWORD东西用户输入。
现在，我一直在测试这个剧本，我的用户密码包含分号之一，所以我们得到这个

where myPassword is something the user entered. now, i have been testing this script and one of my users password contains a semicolon, so we get this

call script2.bat -pw:my;Password

我发现通过把在引号我可以进入第二个脚本确定这
调用script2.bat -pw：我的;密码

I found by putting in quotes I can get this into the second script OK call script2.bat -pw:"my;Password"

不过，在命令行解析休息时，我尝试这样做。

However, the command line parsing breaks when I try to do this

for /F "tokens=1,2 delims=:" %%a in ( "%1" ) DO SET switch=%%a&value=%%b

如果我回声％1就这样表示

if I echo %1 it shows like this

-pw:"my;Password"

但随着脚本运行时我看到回声

But with echo on when the script runs I see

for /F "tokens=1,2 delims=:" %%a in ( "-pw:"my Password"" ) DO SET switch=%%a&value=%%b

并将其解析为开关= -pw和值=我的

and it parses as switch=-pw and value="my

我最终需要的是价值包含我，密码这样我就可以把它传递到另一个程序

What I eventually need is for value to contain my;Password so I can pass it to another program

这是如何得到这个正确解析任何想法

Any ideas on how to get this to parse correctly

下面是再次的issulstrate问题2批处理文件：
一只蝙蝠：
回显

Here re 2 batch file that issulstrate the problem: a.bat: echo on

调用b.bat -pw：eatme
调用b.bat -pw：吃;我
调用b.bat -pw：吃，我
称之为b.bat -pw：\\吃;我\\

call b.bat -pw:eatme call b.bat -pw:eat;me call b.bat -pw:"eat;me" call "b.bat -pw:\"eat;me\""

b.bat：
回显

b.bat: echo on

回声％1

有关/ F令牌= 1,2 = delims：%%一中（％1）确实设置开关= %% A和设定值= %% b

for /F "tokens=1,2 delims=: " %%a in ( "%1" ) DO SET switch=%%a&SET value=%%b

回声开关=％开关％
回声值=％值％

echo switch=%switch% echo value=%value%

谢谢！

推荐答案

我发现了一个小窍门来解决的方式外壳间$ P $在FOR / F环pting的％1的值：代替解析字符串，解析命令的输出 ECHO％1 ，就像这样：

I found a little trick to get around the way the shell is interpreting the value of "%1" in the FOR /F loop: instead of parsing the string, parse the output of the command ECHO %1, like this:

FOR /F "tokens=1,2 delims=:" %%a IN ( 'ECHO %1' ) DO ECHO Switch: %%a Value: %%b

这工作，如果你把密码在命令行上的引号（通话script2.bat -pw =我的;密码），所以我们必须要删除引号如下：

This works if you put the password in quotes on the command line (call script2.bat -pw="my;password"), so we'll have to remove the quotes as follows:

SET VALUE=%VALUE:~1,-1%

这就是我想出了code：

So this is the code I came up with:

ECHO OFF

ECHO Arguments: %1

FOR /F "tokens=1,2 delims=:" %%a IN ( 'ECHO %1' ) DO (
    SET SWITCH=%%a
    SET VALUE=%%b
)

ECHO SWITCH: %SWITCH%

SET VALUE=%VALUE:~1,-1%
ECHO VALUE: %VALUE%

...返回以下结果：

...which returns the following results:

Arugments：-pw：我的;密码结果
  开关：-pw结果
  VALUE：我的;密码

Arugments: -pw:"my;Password"
SWITCH: -pw
VALUE: my;Password
