如果变量开头，Windows批处理检查结尾，并包含一个特定的字符串 [英] Windows Batch check if variable starts with, ends with and contains a specific string

问题描述

我想检查是否在批处理文件中的一个变量启动包含试用版的地方，并结束与）。

这可能吗？
如果是，可能有人帮助我吗？

解决方案

  @ECHO OFF
SETLOCAL
SET VAR = ABC＆放大器; CALL：检查
SET VAR =ABC和放大器; CALL：llcheck
SET VAR =）及CALL：检查
SET VAR =）＆放大器; CALL：llcheck
SET VAR = ABC）与＆amp; CALL：llcheck
SET VAR = xyzbetazyx＆放大器; CALL：检查
SET VAR =xyzbetazyx＆放大器; CALL：llcheck
SET VAR = xyzbetazyx）和安培; CALL：llcheck
SET VAR = xyzbetazyx）和安培; CALL：检查
SET VAR =xyzbetazyx）及CALL：检查
GOTO：EOF
:: LOP最后，再检查
：llcheck
SET VAR =％VAR：〜0，-1％
：检查
SET结果= N
SET VAR2 =％VAR％
SET varvar =％VAR％＆GT; test1.txt的ECHO％VAR：0.1〜VAR %%：〜-2％
＆GT;的test2.txt ECHO）
FC名为test1.txt的test2.txt＆GT; NUL
IF ERRORLEVEL 1 GOTO完成
SET VAR | FINDSTR / BVAR =|​​ FINDSTR /我测试版GT＆; NUL
IF ERRORLEVEL 1 GOTO完成
SET结果= Y
：完成
ECHO％VAR％开工有BETA和目的）：％结果％
GOTO：EOF
 

哪里有遗嘱......

不平衡可能会非常棘手我只是将它设置平衡，砍掉最后一个字符（设置变量：llcheck 项：LOP最后，检查

Essentiall，我复制到变量 VAR2 和 varvar 在奥德试玩会发生什么情况，这些应该variablenames进行设置。

这两个文件的生成，然后。 test1.txt的包含 VAR 和的test2.txt 简单）

比较两个 - 如果他们不相同，那么该变量不会启动和结束）另外还有 - 可以简单地写成 VAR 到一个文件，并使用 FINDSTR 找到测试版，但我还是决定送 SET VAR 的输出应该是所有在表单中的 VAR * 变量

  VAR = ABC
VAR2 = ABC
varvar = ABC
 

进入FINDSTR，发现启动一（ / B ） VAR = 和发现是否的 THAT 的包含字符串测试版的 / I 选择不区分大小写。如果你想具体试用版在大写，只需更改测试版到试用版和删除 / I 。

结果设置为是或 N

I'm trying to check if a variable in a batch file starts with " contains BETA somewhere and ends with ").

Is it possible? And if yes, may somebody help me with that?

解决方案

@ECHO OFF
SETLOCAL
SET var=abc&CALL :check
SET var="abc"&CALL :llcheck
SET var="")&CALL :check
SET var=")"&CALL :llcheck
SET var=abc")"&CALL :llcheck
SET var=xyzbetazyx&CALL :check
SET var="xyzbetazyx"&CALL :llcheck
SET var=xyzbetazyx")"&CALL :llcheck
SET var=xyzbetazyx")"&CALL :check
SET var="xyzbetazyx")&CALL :check
GOTO :eof
:: Lop last, then check
:llcheck
SET var=%var:~0,-1%
:check
SET result=N
SET var2=%var%
SET varvar=%var%

>test1.txt ECHO %var:~0,1%%var:~-2%
>test2.txt ECHO "")
FC test1.txt test2.txt >nul
IF ERRORLEVEL 1 GOTO done
SET var|FINDSTR /b "var="|FINDSTR /i "beta" >nul
IF ERRORLEVEL 1 GOTO done
SET result=Y
:done
ECHO %var% starts " has BETA and ends ") : %result% 
GOTO :eof

Where there's a will...

Setting variables with unbalanced " can be tricky. I just set it up balanced and lopped off the last character (:llcheck entry : lop last and check.

Essentiall, I've copied the variable into var2 and varvar in oder to demo what happens should these variablenames be set.

Two files are then generated. TEST1.TXT contains the first and last 2 character of var and TEST2.TXT simply "")

Compare the two - if they're not identical, then the variable does NOT start " and end ") Otherwise well - could simply have written var out to a file and used findstr to find beta, but I decided to send the output of SET var which should be the contents of ALL of the var* variables in the form

var=abc
var2=abc
varvar=abc

into findstr, finding the one that starts (/b) var= and finding whether THAT contains the string beta The /i selects case-insensitive. If you want specifically BETA in UPPER-CASE, simply change beta to BETA and remove the /i.

result is set to Y or N
