Steven Schubiger scripsit: > a) allocate memory for each line and buffer accordingly
That won't work, because the input size is unlimited and memory is not. You need to be able to fall back to disk. > b) disallow inverted (relative to EOF) line positions That's insufficient too; just allowing out-of-order ranges means that some kind of buffering will be needed. The only safe strategy is to do what "sort" does, and copy the input to a disk file. -- Why are well-meaning Westerners so concerned that John Cowan the opening of a Colonel Sanders in Beijing means [EMAIL PROTECTED] the end of Chinese culture? [...] We have had http://www.ccil.org/~cowan Chinese restaurants in America for over a century, and it hasn't made us Chinese. On the contrary, we obliged the Chinese to invent chop suey. --Marshall Sahlins _______________________________________________ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
