**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 '
' 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
**BUGS**

Even though you can do zero padding on simple ranges, like 001..100, it will not pad zeros on complex ranges like 001..100i2, or for
counting downwards.
