If you still have a machine that runs  classic OS 9 or less - like this 8500 
that I still love - you can use Apple's MPW shell to edit large files.

MPW was written when 8 MB was a LOT of RAM and it still retains its ability to 
"window" the file for editing while remaining most of the text on disk only. 
That was a common technique in the days of dumb terminals and a shared DEC box.

MPW  handles large log files pretty well and you can script editing commands on 
one window that can be applied to another which is designated as a target. The 
ENTER key is used as in a BBEdit worksheet.

And one no longer has to pay for MPW. It's downloadable from Apple.com.

Something else I have tried with some success on large apache log files is to 
use substitute commands, line by line, in a perl script to replace very common 
strings, such as the first parts for a path name, with a couple of unique 7 bit 
ASCII characters. A few substitutes carefully chosen can reduce file size to 
25%. Think of it as intelligent use of LZW compression.

After editing in BBEdit the file can be re-expanded in perl but whit happens is 
that I remember the substitutions and they just stay that way.
