But it's not necessarily good to include all possible ways. I mean,
this works too:
perl -ple '$_=$^T'<<<1
But that's not exactly self-documenting. Plus it's a bitch to embed in
a script because of all the quote characters, and finally, it uses a
bashism to provide a single line on stdin :) (if you don't use bash,
add "echo|" in front and remove the "<<<1").
I optimised for keystrokes, and less complicated characters that
possibly need quoting.
You could also optimize for the non-existance of perl, and use awk,
which might be even more uniformly available (eg, modern FreeBSD
comes without perl if you do a bare bones install. Then again,
FreeBSD date groks %s).
So, TIMTOTDI squared (look ma', no perl!). This does the same as
date +%s too:
echo|awk '{print systime()}'
