I have to finally admit it: I have stopped complaining about spam. Moreprecisely, I've stopped writing and sending complaints about spam to theISPs that they come from.

This is because I've pretty much given up hoping that a complaint to thetheoretically responsible ISP is at all worth my time and will produceany meaningful results. I am tired of writing more or less form lettersto tell ISPs that they have yet another phish spammer, yet anotherclueless free webmail provider spewing advance fee fraud, yet

I was reminded of this by seeing it in a shell script recently: theorder that you do redirection in on a command line can be important.This means that the following two lines are not equivalent:

foobar 2>&1 >/some/wherefoobar >/some/where 2>&1

The first one sends standard error to wherever the current standardoutput is, and then sends standard output to /some/where ; the lattersends both standard output and standard error to /some/where .
