Extract lines without no spaces into a text file through a batch file

Thanks in advance for your valuable inputs Through a batch file,I'm trying to read line by line a text file except those starting with space.

I have tried this:

for /f "eol=^"" " %%x in (file.txt) do echo. %%x>out What I have done is also reading lines from file begining with spaces.

I also tried this: for /f "tokens=*" %%a in ('find /v ^" " %1') do ( echo.%%a pause console output is empty.

Assume that my file looks like this one:

Draw something

******* STEP 1 ********

Draw something else

============================ ...............................

For this example, I have to read one line after another one

Draw something

Draw something else

Any help!!

You found the correct FOR /F option, but you failed to find the correct usage. All lines that begin with the EOL character are skipped, and the very next character after EOL= is always the EOL character. You simply want a space after the equal.

You also want to preserve the entire line, so you need to set DELIMS to nothing.

for /f  "eol= delims=" %%x in (file.txt) do echo. %%x>out

Peter Wright's FINDSTR solution is a simpler way to eliminate lines that begin with space. But I'm assuming you want to do additional processing with each line that does not begin with space.

Oh, that's an easy one!

findstr /v /b /c:" " <file.txt

finds lines EXCEPT /v begin with /b the literal string " " /c:" "

see findstr /? from the prompt for docco...
