I have a 2gig file (leunig's interview thismorning on ABC classic fm) that i only need the first 700mb of, i haven't the disk space to dd it, i'm looking to just chop off the last 1.3gig or so. Any commands to do this? Can clib do this? Also i have wanted to zero length a file in the past, ie. just keeping the filename.... thx, Simon Burton.
