numrange(1)


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

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.
