Reading values from file and assigning it to variable in batch script
提问by Shekhar
I want to read the file which contains the value of some variables which are used in my batch script. I have created a property file with format
我想读取包含批处理脚本中使用的某些变量值的文件。我创建了一个格式的属性文件
key=key_value
key=key_value
Now, I want to set environment variable's name as key and its value as key_value How can I assign?
现在，我想将环境变量的名称设置为键，将其值设置为 key_value 如何分配？
I have read the file but cannot separate the string "key=key_value" into two strings. Thanks in advance.
我已阅读该文件，但无法将字符串“key=key_value”分成两个字符串。提前致谢。

With the FOR command you can turn your key/value file from this
使用 FOR 命令，您可以从这里转换您的键/值文件
KEY1=value
KEY2=value
into this
进入这个
SET KEY1=value
SET KEY2=value
which you can then invoke as a batch file to set all of the keys as environment variables. this only works if all of the keys are unique, but from your question it sounds like they are.
然后您可以将其作为批处理文件调用以将所有键设置为环境变量。这仅在所有键都是唯一的情况下才有效，但从您的问题来看，它们似乎是唯一的。
save this as a batch file
将此保存为批处理文件
@echo off
echo rem generated from keyvalue.txt > keyvalue.bat
for /F "tokens=*" %%I in (keyvalue.txt) do @echo set %%I >> keyvalue.bat
call keyvalue.bat
This .bat code assumes that your key/value file is keyvalue.txt and that there are no lines other than blank lines or key=value pairs.
此 .bat 代码假定您的键/值文件是 keyvalue.txt 并且除了空行或键=值对之外没有其他行。
