This is (I think) the World's First One-Liner Perl web counter. Touch counter.dat before running.

The WFOLPWC was written on Linux. Other platforms may or may not be able to use this, your guess is probably better than mine.

Don't forget to touch counter.dat before running this:

perl -e 'print "Content-Type = text/html\n\n";open(F, "counter.dat");w
+hile (<F>) {$c = $_};chomp $c;$c++;print "$c\n";close F;unlink "count
+er.dat";open(N, ">counter.dat");print N "$c";'

And since code tags make copying and pasting one-liners less than ideal:

perl -e 'print "Content-Type = text/html\n\n";open(F, "counter.dat");while (<F>) {$c = $_};chomp $c;$c++;print "$c\n";close F;unlink "counter.dat";open(N, ">counter.dat");print N "$c";'

And for the anally retentive file locking crowd: (Code changes by wog)

perl -MCGI -MFcntl=:flock,:seek -e'print CGI->new->header;open F,"+<counter.dat";flock F,LOCK_EX;print $b=<F>;seek ,0,SEEK_SET;print F ++$b;'
