$ diff -s output output1
Files output and output1 are identical

If i want to put this code in a script
#! /bin/awk -f
(...)

what is the correct syntax? i'm unable to run this from a script. Thank you in advanced.

Here is the file:
Code:
$ cat awk.file
{
  OFS=""
  a=toupper($0)
  b=substr(a,1,109)
  d=substr(a,112,10)"    0    1 \""
  e=substr(a,123)"\" 0"
}
{
  if(NR==5)c="1f"
  else c="  "
}
{
  print b,c,d,e
}

Ok, thank you very much indeed, i see that is not mandatory to use
#! /bin/awk -f
blah blah blah

My last question (in this thread), please, how is the way to put in a script (script.awk file) this type of command-line awk's?

awk -F'[ ]' '{ /[0-9]+/ && $NR > 6 && $NF = "0 1"; print}'

I think is a problem with the quotes, and i don't know how to scecify the -F'[ ]'
parameter. Thanks!!!

Code:
$ cat awkprog
BEGIN{ FS="[ ]" }
/[0-9]+/ && $NR > 6 && $NF = "0 1"

Code:
$ awk -f awkprog file
