batch script - read line by line

Question

I have a log file which I need to read in, line by line and pipe the line to a next loop.

Firstly I grep the logfile for the \"main\" word (like \"error\") in a sep

Answer 1

This has worked for me in the past and it will even expand environment variables in the file if it can.

for /F "delims=" %%a in (LogName.txt) do (
     echo %%a>>MyDestination.txt
)
