批处理脚本 - 从文件中读取行时忽略哈希

Question

我想在属性中设置名称值对的变量.属性文件有#作为注释

====示例输入文件=====

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

DEV.key1=value1
TEST.key2=value2

=========我有2个问题

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

变量已设置,但我希望忽略注释.我想用一行代码执行此操作,但请改为使用.

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)我希望将此属性文件作为参数传递给批处理脚本.test.bat文件的内容

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

产量

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

如果我一次运行一行这个文件的内容,它就可以了.我究竟做错了什么？提前致谢

Answer 1

要忽略以哈希开头的行,可以使用eolfor循环的参数.
for /f "eol=# delims=" %i in (test.properties) do @set %i

第二个问题是将批处理文件内的百分比加倍.

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

这是由解析器引起的,命令行和批处理文件有不同的规则.

CMD线
for %a in (xyz) do echo %a

批处理文件
for %%a in (xyz) do echo %%a
