How to set an env variable with multiline file content in windows command prompt
In Windows Command Prompt, you can set an environment variable with multiline file content using a combination of commands and input redirection. Here's an example:
shellset /p VAR_NAME=<file.txt
In the example above, VAR_NAME
is the name of the environment variable you want to set, and file.txt
is the file containing the multiline content.
Ensure that file.txt
contains the desired multiline content, with each line terminated by a line break (carriage return and line feed).
When you run the set /p
command with input redirection <
, it reads the content of the file and assigns it to the environment variable specified on the left side of the command.
After running the command, you can verify that the environment variable is set correctly by typing echo %VAR_NAME%
in the Command Prompt. It should display the multiline content of the file.
Note that this method sets the environment variable for the current Command Prompt session. If you need the environment variable to be persistent across sessions or available to other processes, you may need to use a different method, such as modifying the environment variables in the System Properties settings or using a script to set the variable during system startup.
Additionally, be cautious when setting environment variables from external file content, as it may introduce security risks. Make sure the content of the file is trusted and properly validated before using it as an environment variable.
