I think the OP wants to see the numbers (works only with GNU tr command on Linux):
Code:
 awk  '{ for(i=1;i<=NF; i++)
          if( $(i) ~ /[0-9]{6}+/)
          {
            printf("%s\n", $(i) )
          }
       }'  filename | tr -dc '[[:digit:][:cntrl:]]'
123456
333444
111111
444444

NAME
gsl-histogram - compute histogram of data on stdin SYNOPSYS
gsl-histogram xmin xmax [n] DESCRIPTION
gsl-histogram is a demonstration program for the GNU Scientific Library. It takes three arguments, specifying the upper and lower bounds of the histogram and the number of bins. It then reads numbers from `stdin', one line at a time, and adds them to the histogram. When there is no more data to read it prints out the accumulated histogram using gsl_histogram_fprintf. If n is unspecified then bins of inte- ger width are used. 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
