A look at Gawk 4.0.0

Awk & awk scripts are still useful.

For example Perl & Python are huge, their size is in MBs whereas configuring awk[1] to Busybox increases Busybox size only by some KBs. Sometimes size matters. Sometimes Perl or Python aren't otherwise available.

[1] Busybox AWK isn't 100% POSIX compliant, but the few POSIX features it's lacking are marginal (I've only bumped into one, some rarely used printf format feature which I don't anymore remember).

I use gawk almost daily when analysing data files with gnuplot. Like this :-)

plot "<awk -v I=7 -f RSH2.awk --s '/^E/ && $F1<1000*mV && $F2<1000*mV && $BH<20*mV && $DH>15*mV{print $F1/mV, $F2/mV}' radpf-2011-06-27-muons-horizontal-3.E | ./hist.py -s 0.5 -S 0.5" with image

Oh Noes!

You are providing fodder for those who want Jon to start deleting comments.

Oh Noes!

It's no uglier than MUMPS code.

(In any case, I'd look out: from the look of that comment, SiB could be firing ionized plasma from an underground death ray any time now.[1])

[1] sure, they *say* it's a particle accelerator...

Oh Noes!

Particle Accelerator or Death Ray.

It all depends on which direction you point the thing.

Ah, that's where perl gets its line noise from.

AWK is no where near as bad as Perl, imo. There are no variable context operators that mean you have stick funny chars in front of every variable reference (vars are referenced just by name - $ is just a field dereference operator that acts on vars). The uglyness here is primarily just from its inherent nature as being a very long conditional to control a print statement, and squashing it all on one line.

Yet more language trolling. Nothing to see here, move on...
