find out which byte terminates the first 300 lines. maybe... ~$ BYTES=$(head -300 nameofbigfile.txt | wc -c)
then use that info with dd skip the first part of the input file... ~$ dd if=nameofbigfile.txt of=truncatedversion.pl ibs=$BYTES skip=1 one of many ways, I'm sure. I think this way should be pretty fast because it works on a line by line basis for just a small part of the file. The rest, with dd, is done in larger pieces. - Anna On Wed, Jun 28, 2006 at 01:01:03PM -0700, Grant Kelly wrote: > Alright unix fans, who can answer this the best? > > I have a text file, it's about 2.3 GB.
