Question

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?

Answer 1

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 /?
