Splitting big files
Can anyone tell me a simple way to split big files in linux?

I have an access log that is over 1 Gig in size and I want to split it into a 700meg chunk (that I can burn to a CD) and whatever is left over I'll leave as the access log.

I really don't think I want to try this with vi ;-)

Thanks M.Hirsch,

That's exactly what I was looking for.

I was just about to start playing with the dd command.

dd can do the same job too.

you could do:

dd if=access_log of=acces.part.01 bs=1024k count=700 skip=0
dd if=access_log of=acces.part.02 bs=1024k count=700 skip=700
dd if=access_log of=acces.part.03 bs=1024k count=700 skip=1400
...
... i.e. put it inside a for-loop ....

(untested, maybe the syntax slightly differs)

but now that we have "split", why?

Grüsse,
M.Hirsch
