Malcolm,
My experience with extracting lines from big files (10-20 MB that
must be processed in less than a few seconds) is that the first
question is, do they use return or linefeed as the line delimiter?
and is it an option for you to change your line delimiter? Indeed,
'tr' would be several seconds on a big file, so you *have* to bear
with the line delimiters you've got in the first place.
If it's linefeed, then the shell tools are very helpful.
If it's return, Satimage's find text / ufind text / change / uchange
suite may be more helpful.
Emmanuel
