On Linux, why not look at /proc/net/dev? That would give you realtime information, it's standard on Linux no matter what user software you might be using, it should get everything, and it's easy to access (although find-file doesn't work on it---should it? if not, why not? ---`M-! cat' does). One reason I suggest this is that we should probably be poking around in /proc to see just how many system utilities could be simplified or standardized on Linux by using it. Note that a lot of things can be read from a running Linux kernel that way, some of which don't have standard tools for access (eg the new kmod and IrDA subsystems). That might almost justify the lack of portability to systems without proc-fs. -- University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Institute of Policy and Planning Sciences Tel/fax: +81 (298) 53-5091 __________________________________________________________________________ __________________________________________________________________________ What are those two straight lines for?
