I've never seen grep use more than 100% CPU on my 4 processor SMP box for instance. Maybe there is some flag I don't know about? I guess my question is, are people expecting them to become anything but serial in the near future, or is that too much of an edge case?

Maybe try the Gnu forum? http://www.nabble.com/Gnu-f1458.html It is possible to use Bash scripts to divide tasks and run the bits simultaneously on multiple CPUs. I call this "poor man's parallelism". I've done it with some of my own programs, but it should be possible with utility programs. But as to whether they are planning to enable the programs themselves to run on multiple CPUs, I don't know. Given multicores, and the growing popularity of SMP machines, it seems that it would be a good idea. Take the red pill Climate Change Blog Food Weblog
