Cool! Except it returns Fri Feb 13 18:31:30 EST 2009. I wonder where the 3hrs 5min different came from?
Grep the archive! http://www.commandlinefu.com/commands/view/1793/then-end-of-the-unix-epoch
On OS X and BSD variants the equivalent seems to be
date -r 1234567890
[[ `grep -i ego jnash | wc | awk '{print $1}'` -gte 1 ]] && echo "Yep! ;-)" || echo "My bad"
Nice trick. I usually use 'perl -e "print localtime 1234..."' but this is clearly better.
Not solaris compatible...
Oh god, I wish I knew of this last year. I learned the BSD (in my case OSX) version of date -r 1234567890 and loved it. I talked to a friend of mine and he suggested something along the lines of;
date -d "1234567890 seconds ago UTC"Needless to say I have a new better way of doing it.
