Dump batch script output into a text file without specifing batchfile location beforehand
The only solution I can think of is adding >> output.txt at the end of every command outputing something of your batch file. It will add the output of your file at the end of output.txt
Or creating a second batch file which content would be .\MyBatchFile.bat > output.txt.
Enclose your commands in round brackets. MyBatchFile.bat:
@echo off
REM setlocal enabledelayedexpansion
(
echo line one
echo line two
echo line three
) > "%~dpn0.txt"
Variables inside the brackets are evaluated all at once when ( is encountered. Use enabledelayedexpansion to delay the evaluation.
