In Plan 9 it's named "seq". I've been using this approximation:
#!/bin/perl
require 'getopts.pl';
$opt_f = "%g\n";
do Getopts('f:');
if ($#ARGV == 2) {
$start = $ARGV[0]; $step = $ARGV[1]; $end = $ARGV[2];
} elsif ($#ARGV == 1) {
$start = $ARGV[0]; $step = 1; $end = $ARGV[1];
} elsif ($#ARGV == 0) {
$start = 1; $step = 1; $end = $ARGV[0];
} else {
die "usage: [-f fmt] [start [step]] end\n";
}
$opt_f =~ s/["`\$\@]/\\$&/g;
for ($n = $start; $n <= $end; $n += $step) {
eval 'printf "' . $opt_f . '", $n';
}
