csplit would cover the case where the input file is text, to be split on line boundaries based on patterns found within the lines; but the example given looks like a binary pattern and my reading of the inquiry is that the split should occur at the pattern rather than at a nearby newline. Grepping the ports INDEX for "split" yields the following candidates which might bear examination, to see if any of them will work: misc/granulate sysutils/gfslicer sysutils/hoz sysutils/lxsplit _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
