Second...about the passing argument ot awk script.
I tried the way awk -f generate.awk data.dat awk_serial=$serial

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
