At How can I find tomorrow's or yesterday's date in a script?, some anonymous
person left what I consider to be a stupid comment.
Now before anyone gets their politically correct hackles all
aroused, I am not implying that the person who left the comment
is bereft of intelligence, is incapable of intelligent comments,
is unworthy of human association and so on. We all say stupid things
now and then: we are momentarily distracted and unthinking, we're
in a hurry, whatever. If there exists a person who has never once
said or done something stupid, I don't want to know them: I wouldn't
like them at all.
In this case, the answer (one answer) was right on on the page
itself: for a SCO system lacking GNU date, he could download
the "datemath" package and simply do "datecalc +1". If he were running
Linux, "date --date=tomorrow" is a simple way to do it. On
Mac OS X, you could do:
date -r `expr $x + 86400`
Or, as the original page suggested, you could use Perl. You could
find all that and more scattered across this site in various places if
you bothered to look.
With a very little effort, almost anyone should be able to
figure that out themselves: "man date" is a good start. It
might take a little more effort to get to the "date +%s" solution":
you might need "man strftime" also. But it is all there.
Ahh, but why isn't it all just in one place? Some folks are
in a hurry, as we noted, and don't have time to research and think: they
just want the magic incantation. that will solve their problem. We can do that, but it
Otherwise, you have to turn the brain on for a few minutes and pay
