command.exe < file.txt

That command would redirect the contents of file.txt to command.exe.


For example, if file.txt contained hello world,  then set /p var=<file.txt would result with the contents of file.txt to be stored to %var%.

A complete batch file script utilising command redirection would be:

@echo off
echo hello 1234 > doc.txt
set /p contents = < doc.txt
echo The contents of "doc.txt"="%contents%"
pause
exit

Here are some links that further explain command redirection:
