批处理脚本 - 从文件中读取行时忽略哈希 [英] Batch script - Ignore hash when reading lines from a file

问题描述

我想设置从名称值对变量的属性。属性文件有＃征求意见

I would like to set variables from name value pairs in a properties. The property file has # for comments

====示例输入文件=====

====sample input file=====

#This is a comment
### Another comment
appNames=HelloWorldApp
targetServer=serverABC

DEV.key1=value1
TEST.key2=value2

=========
 我有2个问题

========= I have 2 issues

1）

C:\temp\dos>for /f "delims=" %i in (test.properties) do @set %i
Environment variable #This is a not defined
Environment variable ### Another not defined

变量的设置，但我想被忽略的意见。我想用code一行做到这一点，但得到这个代替。

Variables are set, but I would like comments to be ignored. I would like to do this with a single line of code, but get this instead.

for /f "delims=" %i in (test.properties) do @echo %i | find "#">nul || @set %i
find: unable to access "#": The system cannot find the file specified.
The process tried to write to a nonexistent pipe.
Environment variable #This is a not defined
find: unable to access "#": The system cannot find the file specified.
The process tried to write to a nonexistent pipe.

2）
我想这个属性文件作为参数传递给test.bat的文件的批量script.Contents

2) I would like this properties file to be passed as an argument to a batch script.Contents of the test.bat file

set propFilePathAndName=%1
for /f "delims=" %i in (%propFilePathAndName%) do echo %i

输出

C:\temp\dos>set propFilePathAndName=/temp/dos/test.properties
propFilePathAndNamei was unexpected at this time.    

如果我同时运行该文件中的一行的内容，它的工作原理。
我究竟做错了什么？
在此先感谢

If I run the contents of this file one line at a time , it works. What am I doing wrong? Thanks in advance

推荐答案

要忽略开始用哈希行，你可以使用 EOL 参数的循环。< BR>
FOR / FEOL =＃delims =％i的（test.properties）做@set％I

To ignore lines starting with a hash, you could use the eol parameter of the for loop.
for /f "eol=# delims=" %i in (test.properties) do @set %i

第二个问题是翻番批处理文件内的百分比。

The second issue is to double the percent inside of a batch file.

set propFilePathAndName=%1
for /f "delims=" %%i in (%propFilePathAndName%) do echo %%i

这是由分析器引起的，也有命令行和批处理文件不同的规则。

This is caused by the parser, there are different rules for the command line and batch files.

CMD行结果
在（XYZ）也呼应%%一个一个

批处理文件结果
为%%一中（XYZ）也呼应%% A
