Two choices:

Redirect (">") your commands in the .bat file directly, as you invoke them

EXAMPLE:

echo %DATE% %TIME% > mylog.txt
cmd1 >> mylog.txt
cmd2 >> mylog.txt
...

Create a 2nd .bat file to call the first, and redirect everything in the first one:

EXAMPLE

call mybatfile.bat > mylog.txt

Side notes:

a. "Text output" actually consists of two, separate "streams": stdout (normal text), and stderr (error text). If you want to redirect both to the same log file, you can use this syntax:

call mybatfile.bat > mylog.txt 2>&1

b. ">" erases the previous contents before writing. ">>" appends the new output to the previous contents of the file.

> outfile.txt or >> outfile.txt may also be stated in front of the command, e. g. > outfile.txt echo Hey.; if the output file (path) contains spaces, enclose it in a pair of " (this might be done in general);

"command 1>&2 Folderpath\mylog.txt" this is not working in my case. Also tried for multiple combinations. I am gettign this error " *** Unrecognized command line argument 'D:\out.txt'. "

Just add a "> filename" after the command you are calling your script and the output will be written into this file ("filename").

See https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/redirection.mspx?mfr=true for more details (appending, ...).

Using code from the answer from @paulsm4:

This method is better than adding a space at the end of each line as there are no extra and unwanted characters.

 > mylog.txt echo %DATE% %TIME%
>> mylog.txt cmd1
>> mylog.txt cmd2

The reason why spaces are used in this method is because some numerals get eaten when there is no space.

echo %DATE% %TIME% > mylog.txt
cmd1 >> mylog.txt
cmd2 >> mylog.txt
