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 separate file - to keep it small. Now I need to take the seperate file and read it in line by line - each line needs to go to another loop (in these loop I grep the logs and divide it in blocks) but I stuck here.

The log looks like

xx.xx.xx.xx - - "http://www.blub.com/something/id=?searchword-yes-no" 200 - "something_else"

with a for /f loop I just get the IP instead of the complete line.

How can I pipe/write/buffer the whole line? (doesn't matter what is written per line)

Try this:

@echo off
for /f "tokens=*" %%a in (input.txt) do (
  echo line=%%a
)
pause

because of the tokens=* everything is captured into %a

edit: to reply to your comment, you would have to do that this way:

@echo off
for /f "tokens=*" %%a in (input.txt) do call :processline %%a

pause
goto :eof

:processline
echo line=%*

goto :eof

:eof

Because of the spaces, you can't use %1, because that would only contain the part until the first space. And because the line contains quotes, you can also not use :processline "%%a" in combination with %~1. So you need to use %* which gets %1 %2 %3 ..., so the whole line.
