FreeBSD did it right from the start, by making all syscalls use 64-bit values for file sizes. The FFS filesystem also supports large files. There is no such thing as a "2gb limit" on FreeBSD. > My main needs are being able to: > cp, mv, compress/uncompress, cat, grep large files (I may be missing > something here, but you get the idea) Tail has problems on large files, but only because it tries to mmap the entire file at once. That's the only program I can remember having problems with. I can personally vouch for cp, mv, gzip, cat, and grep :) > BTW how is the performance of linux binaries running on *BSD in > emulation mode?

You don't take any performance hit by running Linux binaries, and 99.9% of Linux binaries work under the Linuxulator, including Netscape, Oracle8, and Microfocus Cobol. -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
