Hi,

I wanna to generate a pair of random number (range from 1 to 4124) and repeats it 416 times.

Desired output
Code:

123 1256
341 14
3245 645
.
.
.

I did write the below command:
Code:
awk "BEGIN{srand($RANDOM); for(i=1;i<416;i++)print int(1+ rand()*4124)}"
1013
4078
2606

gsl-randist

GSL-RANDIST(1)						      General Commands Manual						    GSL-RANDIST(1)

NAME

       gsl-randist - generate random samples from various distributions

SYNOPSYS

       gsl-randist seed n DIST param1 param2 [..]

DESCRIPTION

       gsl-randist  is a demonstration program for the GNU Scientific Library.	It generates n random samples from the distribution DIST using the
       distribution parameters param1, param2, ...

EXAMPLE

       Here is an example.  We generate 10000 random samples from a Cauchy distribution with a width of 30 and histogram them over the range  -100
       to 100, using 200 bins.

	    gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat

       A  plot	of  the  resulting histogram will show the familiar shape of the Cauchy distribution with fluctuations caused by the finite sample
       size.

	    awk '{print $1, $3 ; print $2, $3}' histogram.dat | graph -T X

SEE ALSO

       gsl(3), gsl-histogram(1).
