AIX

Keeping on topic for a minute... AIX grep doesn't have such "extensions" (and for TRB, most grep's I would imagine, are POSIX compliant, but AIX has extensions of its own (like -p, which make dealing with it's heavily-stanza-based system files easier)).

anbu23 had the correct answer - this question has been asked many times. Search the forums.

Gentlemen,
First, if a read from disk once it was already in the cache disk, for the next reading was not reading from the disk.
Second, the time for entering commands from the keyboard to be unreasonably long, in scripts, in cron, it's OK.
In interactive mode I include the filename after command tail without a cat.

It's formum AIX not intel8080 or z80 now 15 september 2010.

The principle is architecture-independent, and the cost remains large in the fastest machines -- extra process creation, double the reads and writes, much more I/O involving the kernel, many more context switches, and having to wait for it when its dead. If anything it's more important not to waste time and memory in large-scale machines expected to perform consistently under very high loads. You're wasting a core that'd otherwise be doing real work.

Hi,
Let's come back time when not allowed to start X, for a very charged the processor. Only character mode. I can laugh, I remember those time.
If you're teacher, you're right, young computer scientists should think, it's good trening.
