如何读文件内容成批处理文件中的变量？ [英] How to read file contents into a variable in a batch file?

问题描述

该批处理文件从测试到LIVE释放构建。我想在这个文件中，确保有一个SPE cific文件夹中的accomanying发布文档添加一个约束检查。

 C：\\ Program Files文件\\ Windows资源工具包\\工具\\ robocopy.exe\\\\ TESTSERVER \\ testapp $
\\\\ liveserver \\ $ liveapp* * / E / XA：H / PURGE / XO / XD.svn文件/ NDL / NC / NS / NP
德尔\\\\ liveserver \\ liveapp $ \\ web.config中
仁\\\\ liveserver \\ liveapp $ \\ web.live.config的web.config
 

所以，我有一个关于如何实现这一几个问题...

1. 有在 \\\\ TESTSERVER \\ testapp $ 文件夹 version.txt 文件，该文件的唯一内容是版本号（例如，45 - 为构建45）
   我如何读的内容 version.txt 文件导入到批处理文件变量？




2. 我如何检查文件， \\\\文件服务器\\ MyApp的\\ releasedocs \\ {}构建.DOC ，存在的地方使用变量从第1部分{中}建立？

解决方案

读取文件内容到一个变量：

  FOR / Fdelims =%%倍In（version.txt）并设置编译= %%点¯x
 

或

 设置/对构建= LT; version.txt
 

双方将采取同样只在文件中单行线，更多的线为变种就会把的最后的行成变量，而设置/ p 将使用的第一。的

使用变量 - 就像任何其他环境变量 - 这是其中之一，毕竟：

 ％构建％
 

因此​​，要检查是否存在：

 是否存在\\\\文件服务器\\ MyApp的\\ releasedocs \\％建立.DOC％...
 

虽然这可能是没有UNC路径被允许存在。现在不能测试此权利，但请记住这一点。

This batch file releases a build from TEST to LIVE. I want to add a check constraint in this file that ensures there is an accomanying release document in a spe cific folder.

"C:\Program Files\Windows Resource Kits\Tools\robocopy.exe" "\\testserver\testapp$"        
"\\liveserver\liveapp$" *.* /E /XA:H /PURGE /XO /XD ".svn" /NDL /NC /NS /NP
del "\\liveserver\liveapp$\web.config"
ren "\\liveserver\liveapp$\web.live.config" web.config

So I have a couple of questions about how to achieve this...

1. There is a version.txt file in the \\testserver\testapp$ folder, and the only contents of this file is the build number (for example, 45 - for build 45) How do I read the contents of the version.txt file into a variable in the batch file?

2. How do I check if a file ,\\fileserver\myapp\releasedocs\ {build}.doc, exists using the variable from part 1 in place of {build}?

解决方案

Read file contents into a variable:

for /f "delims=" %%x in (version.txt) do set Build=%%x

or

set /p Build=<version.txt

Both will act the same with only a single line in the file, for more lines the for variant will put the last line into the variable, while set /p will use the first.

Using the variable – just like any other environment variable – it is one, after all:

%Build%

So to check for existence:

if exist \\fileserver\myapp\releasedocs\%Build%.doc ...

Although it may well be that no UNC paths are allowed there. Can't test this right now but keep this in mind.
