Adding same value to variables in does each repetition of command
So, I have this command:
I'd like to have the +2 and +6 accumulate here.
In each new gif tackled, it should increase by the amount: +2 (for x) and +6 (for y)
Is anyone know some scripts to generate random number without repetition using bash; for example generate 10 different random numbers.

test::image::gd
Test::Image::GD(3pm) User Contributed Perl Documentation Test::Image::GD(3pm)NAME
Test::Image::GD - A module for testing images using GD
SYNOPSIS
use Test::More plan => 1;
use Test::Image::GD;
cmp_image('test.gif', 'control.gif', '... these images should match');
# or
my $test = GD::Image->new('test.gif');
my $control = GD::Image->new('control.gif');
cmp_image($test, $control, '... these images should match');
# some other test functions ...
size_ok('camel.gif', [ 100, 350 ], '... the image is 100 x 350");
height_ok('test.gif', 200, '... the image has a height of 200');
width_ok('test.gif', 200, '... the image has a width of 200');
DESCRIPTION
This module is meant to be used for testing custom graphics, it attempts to "visually" compare the images, this means it ignores invisible
differences like color palettes and metadata. It also provides some extra functions to check the size of the image.
FUNCTIONS
cmp_image ($got, $expected, $message)
This function will tell you whether the two images will look different, ignoring differences in the order of colors in the color
palette and other invisible changes.
Both $got and $expected can be either instances of "GD::Image" or either a file handle or a file path (both are valid parameters to the
"GD::Image" constructor).
size_ok ($got, [ $width, $height ], ?$message)
This function will check if an image is a certain size.
As with the "cmp_image" function, the $got parameter can be either an instance of "GD::Image" or a file handle or a file path (all are
valid parameters to the "GD::Image" constructor).
height_ok ($got, $height, ?$message)
This function will check if an image is a certain height.
As with the "cmp_image" function, the $got parameter can be either an instance of "GD::Image" or a file handle or a file path (all are
valid parameters to the "GD::Image" constructor).
width_ok ($got, $width, ?$message)
This function will check if an image is a certain width.
As with the "cmp_image" function, the $got parameter can be either an instance of "GD::Image" or a file handle or a file path (all are
valid parameters to the "GD::Image" constructor).
TO DO
Add more functions
This module currently serves a very basic need of mine, however, I am sure as I start writing more tests against images I will find a
need for other testing functions. Any suggestions are welcome.
BUGS
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
CODE COVERAGE
I use Devel::Cover to test the code coverage of my tests, below is the Devel::Cover report on this module test suite.
