PROGRAM:

NAME

numrange - Print out a range of numbers for use in for loops and such.

SYNOPSIS

numrange [-dhV] /<expression>/

DESCRIPTION

numrange will print out a list of numbers based on an expression that you specify. This
is useful for making a list of numbers for use in for loops and so on. Ranges are
inclusive. Ranges of numbers are specified using the .. operator, like this /20..50/,
which means all integers from 20 to 50 inclusive. More complex expressions can be
generated using the commas and the 'i' increment operator.

OPTIONS

-e <set> Exclude the <set> of numbers from the range output. <set>
is a set of numbers separated by commas.
-n <n> Use <n> as the separator between numbers. By default, it
will use a space. Use '\n' or \\n for a newline character or
use the -N option.
-N Just a quick option for using a newline as the separator.

-h Help: You're looking at it.
-V Increase verbosity.
-d Debug mode. For developers

EXAMPLES

All numbers from 1 to 10.
\$ numrange /1..10/
1 2 3 4 5 6 7 8 9 10

From 10 to 1. Counting down.
\$ numrange /10..1/
10 9 8 7 6 5 4 3 2 1

From 1 to 10 and from 15 to 20.
\$ numrange /1..10,15..20/
1 2 3 4 5 6 7 8 9 10 15 16 17 18 19 20

Even numbers from 0 to 10
\$ numrange /0..10i2/
0 2 4 6 8 10

Odd numbers. Notice the starting number in the range expression.
\$ numrange /1..10i2/
1 3 5 7 9

Factors of 3 between 99 and 120.
\$ numrange /99..120i3/
99 102 105 108 111 114 117 120

Decimal numbers
\$ numrange /1.1..2.5i0.1/
1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2 2.1 2.2 2.3 2.4 2.5

And negative numbers too.
\$ numrange /1.0..-2.0i0.3/
1 0.7 0.4 0.1 -0.2 -0.5 -0.8 -1.1 -1.4 -1.7 -2

You can also pad numbers when you are counting up. This is
a trick of how the Perl programming language deals with ranges:

\$ numrange /01..15/
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15
