[Closed] Large text file editor and/or splitter - Windows

Learn ruby or perl, that kind of thing is easypeasy. Or if you've got access to a unix box, head -<number of lines> > cut_file.txt would do it, too.

Probably true - lets assume I want to do this today, and conceivably may never get myself into this mess again 😉

Or if you've got access to a unix box

Hmmm..... we will have a Unix machine landing in about a week, which is about a week too late.

Any other suggestions?

textpad? Not sure if can handle that sort of size, but its free. Works ok with our CDR files.

Put it in a database? Have you got MS Access?

Rich - not a bad shout that - don't have Access as part of our Office install though. Grr....

How about:

http://www.gdgsoft.com/gsplit/

1. Download "UnxUpdates.zip" from http://unxutils.sourceforge.net/
2. Expand the zip somewhere
3. Open cmd.exe
4. c:\somewhere\split.exe my_really_big_file.log

This will create n 1000 line files in the same directory - use the -l option to change the file size.

4. c:\somewhere\split.exe -l 10000 my_really_big_file.log

Edit: 100% free.
Edit2: Windows.

Lemonysam/mogrim - many thanks. Looks like both those solutions will do the same thing/are ideal. Thanks again.

Mogrim's suggestion looks good. You could also try [url= http://www.ultraedit.com/downloads/ultraedit_download.html ]Ultraedit's free trial[/url] (normally costs $60) if it's just for today.

1. Install perl.

2. Put the stuff below ---- in a text file textfilesplitter.pl.

3. Run textfilesplitter.pl and follow instructions.

close ( INPUT );
$totalcount = $totalcount + $count;
print "Total lines processed: $totalcount\n\n";

Tried Emacs? There is a Windows port.

All done now - gsplit did it fine.

I did see the Windows port for Emacs..... but (as with the Perl solution) I don't really want to spend more than 5 mins on this as the data manipulation is where the effort is at..... and there is - inevitably - a deadline on it.

Thanks again all.

Other editors may exist - but this is infinitely better named: [url= http://www.brothersoft.com/chainsaw-8796.html ]CHAINSAW!!!!!![/url]

My go-to for straightforward viewing (usually a big logfile I need to se the end of) is [url= http://www.baremetalsoft.com/baretail/ ]Baretail[/url]. Blazing fast as it only shows you the bit of the file you're actually looking at.

get textpad, should do it.
And if you buy a licence you also get wildedit which is a pretty powerful editor
