How to read a text file into an environment variable?

I have a one line text file (it will always be just one line). For example:

helloworld.txt contains "hello world"

I want to read this into an environment variable via the command prompt.

so Set MyVar=somehow reads helloworld.txt

Does anyone know how to do this?

set /P VARNAME=<FILENAME.TXT

This will only work with first line and will handle everything up to the end of the line.

This only works because you want the last line (or a one-line file).

for /f "delims=" %f in (helloworld.txt) DO Set MyVar=%f

For more information, use

for /?
