The other day I found myself unable to count field sizes accurately so I
wrote this little helper.

NR == 1 { # Pick a line
     print
     nf = split(FIELDWIDTHS, fw)
     for (i = 1; i <= nf; i++)
         for (j = 1; j <= fw[i]; j++)
             printf "%d", (i % 10)
     print ""
}


Example:

with FIELDWIDTHS = "1 3 5"

Output:

A dummy line from a file
122233333
