But (and I think we've had this generic argument before), Sun's/SGI's/whatever's may not. So it's a bad idea to get in the habit. And dd(1) is more versatile anyway. What's more, split(1), by default, divides a file into files of "1000 lines", and doesn't have a good way to specify a byte boundary, which is what you really want to specify. (A binary file may simply not contain a ^J or a ^M anywhere.) GNU's -b flag sort of lets you do this, but it may make reconsruction later complicated. (Was there a CR? Was there an LF? Were there both? Neither? Did split(1) swallow them?) dd(1) is the Right tool for breaking up files along byte (or disk block, or whatever arbitrary size larger than a byte you like) boundaries. -- gabriel rosenkoetter gr@eclipsed.net Attachment:
