DOS batch command to read some info from text file

Question

I am trying to read some info from a text file by using windows command line, and save it to a variable just like \"set info =1234\"

Below is the content of the txt

Answer 1

Here's a one line version:

for /f "tokens=2" %%i in ('findstr Revision: input.txt') do set revision=%%i

1. findstr is used to filter the file. It will print "input.txt:Revision: 1234"
2. Then the "tokens=2" means that we are interested in the second token, "1234". By default for breaks on white space.
