I didn't know about the units program. Is there any resource out there that lists these little *nix utility programs?

info coreutils is a great place to start.

Earlier quoted context omitted.

What do you use it for?

One use is converting columns of numbers into math strings for bc. Example (contrived): $ seq 10 20 | paste -s -d + 10+11+12+13+14+15+16+17+18+19+20 $ seq 10 20 | paste -s -d + | bc 165 Or converting columns of strings into regex 'or' clauses for searching (contrived example again): $ cut -f 3 -d , something.csv | paste -s -d "|" a|b|c|d|e|f $ egrep "$(cut -f 3 -d , something.csv | paste -s -d "|")" another_file ...…

ahah, so that's where R's paste() function comes from...

Who though it was going to be a TTL issue before finishing reading the story? :)

You probably mean something else (RTT?) but definitely not TTL, which is a completely different thing :)

TTL is involved when dealing with routed networks. The farther the destiny, you normally get more hops on the way. If the starting TTL is low, you won't reach the destiny. So, TTL values cause problems like this, although the radius wouldn't be so precise. Damn statisticians!

Another email incident at Microsoft worth reading [1]. [1] http://blogs.technet.com/b/exchange/archive/2004/04/08/10962...

Thanks for the link. I was surprised that it was written by Larry Osterman. I enjoy listening to his stories about Microsoft. Have you seen his Channel 9 videos [0]? I really enjoy the checking in videos with Erik Meijer.

I tried the 'units' program on OSX. It seems that it does not recognise the 'millilightseconds' unit.
