Hi, I've generated a text file, with a specific program, but the problem is I need to run this file against another program, and it doesn't accept empty lines in between text. The program is not able to generate it without empty lines, I tried that. Question then remains, I have a simple text file, with empty lines. How do I remove the empty lines ? I do have an sed.exe (non-MKS), but even here I can't get it to work.

I reckon SED.exe can do it, but I'm not certain, and I don't remember hot to use it. The trick is to replace the ocurrances of (characters in hex values) "DADA" by "DA". D is the Carriage Return character, and A is the Line Feed character. Together, they make the CR/LF pair, which marks a line break. If you have a double line break, you have a blank line. You can use another utility, SBS2.COM, which is what this batch file does: ===== BATCH SCRIPT BEGIN ===== @echo off if "%1"=="" for %%? in (echo goto:help) do %%?

If there are not too many blank lines and you are happy to remove them manually, why not simply use edit or edlin. Usually CNTRL + Y removes the line the cursor is on. Alternatively a word processor will do the job and thenoutput as an ascii file. Good luck! u

Thanks, I try the script you mention, it looks sort of weird, but if it works, I am more than happy to use it ! Will post if it works or not ... Anyway, Mike, thanks for the info also, but I need to do it in batch ..

Doesnt seem to work creates batchfile, but this com file doesnt do anything, creates no output whatsoever

looks like it is somewhat easier via sed sed "/^$/d" does the job thanks all anyway
