"Delete or forward, then delete"

pg 130 (Ch 10, Email Management, "Delete or forward, then delete") I also don't reply to emails spreading the latest hilarious Internet joke - such as when I learned about a seven-year-old boy in England, named Craig Shergold, trying to get into the _Guiness_Book_Of_World_ _Records_ by amassing the largest postcard collection. Oh wait, that's an urban legend. It isn't an urban legend; it is a real story that is no longer relevant because he made the record. I would change: Oh wait, that's an urban legend. to Oh wait, he's no longer collecting them.

Note from the Author or Editor:
I'm conflicted because while you are correct, my version reads better to someone that isn't "in the know". I would ask O'Reilly to change it to "Oh wait, that's now just an urban legend."

added a second paragraph: Note: When the web pages move from one server to another, SSH will display a big, scary warning about the encryption keys changed. SSH remembers information about a host, and when you connect to the same machine and the information doesn't match, it displays a warning to indicate that there may be a "man-in-the-middle" security attack going on. When you see this, you should verify that the server really did change and then update your "known_hosts" file (delete the now-obsolete line). You can think of this as a way to notice when the server move has happened. Obviously if the data moves from server to server often, this will become annoying, making the technique less useful. ########################################

makeimage1 script example

http://www.oreilly.com/catalog/timemgmt/errata/timemgmt.307 states: > ######################################## > > {175} line 1, line 4, line 5 > > $* > -> > $@ > > (three occurrences) > > ######################################## pg 175, line 1, (corrected) thus reads: > The $@ in the makeimage1 script... The other two occurrences cited in the above correction likewise refer to the same script (bottom of 174). However, while the description of the makeimage1 script on 175 was updated in 3/07, the script itself was not updated, and still reads: > mkisofs _D -l -J -r -L -f -P "Limoncelli" -V `date -u %m%d` $* The "$*" at the end of the script should, it would therefore seem, be changed to "$@", in keeping with 3/07 {175} line 1, line 4, line 5. (The same error appears to have also been corrected in 3/07 {175} code example, line 1 and 3/07 {177} code example, line 1.)

The getopt described there and used in the following example is not a bash function/built-in; see http://software.frodo.looijaard.name/getopt/ for details.

Yiorgos Adamopoulos sent me email saying that on his copy, page 182 lists: sudo tcpdump -l -n arp | head -100 > /tmp/x | grep 'arp who-has' but the correct code is: sudo tcpdump -l -n arp | grep 'arp who-has' | head -100 > /tmp/x The printed copies that I have at home look correct. Maybe this error was introduced in a new printing? --Tom Limoncelli (author)
