Hi Chubler_XL

thanks for your help:

1) doesn´t works i get an error for

Code:
awk: invalid -v option

2) doesn't works i get an empty file

Code:
WORD,TOTFrequency,(1)Frequency,(0)Frequency,(-1)Frequency,(1%)Frequency,(0%)Frequency,(-1%)Frequency,NV

Anyway, i guess we have to look at your first version:

Code:
#!/bin/bash
awk -F, '
NR>1 {
   split(tolower(substr($0, length($1","$2",")+1)), words, "[^A-Za-z_\047]")
   for(wnum in words) {
       w=words[wnum]
       if(length(w)>=4) {
          counts[w]=counts[w]+1
          freq[$1,w]++
       }
    }
}
END {
  OFS=","
  print "WORD,TOTFrequency,(1)Frequency,(0)Frequency,"\
        "(-1)Frequency,(1%)Frequency,(0%)Frequency,(-1%)Frequency"
  for (w in counts) printf ("%s,%d,%d,%d,%d,%0.1f%%,%0.1f%%,%0.1f%%\n",
         w, counts[w],
         freq[1,w]+0, freq[0,w]+0, freq[-1,w]+0,
         freq[1,w]*100/counts[w],
         freq[0,w]*100/counts[w],
         freq[-1,w]*100/counts[w]) | "sort -t, -k2,2nr -k1,1"
}
' file

From here, can you implement in one .sh all features?

About NV, his value depends from values in columns (1)Frequency and (-1)Frequency!

example:
Code:
WORD,TOTFrequency,(1)Frequency,(0)Frequency,(-1)Frequency,(1%)Frequency,(0%)Frequency,(-1%)Frequency,NV
day,6832,3562,1117,2153,52.1%,16.3%,31.5%,0.24

Where NV=3562-2153/(3562+2153)=0.24

Thanks for your help and attention.

lp-shell

lp-shell(1)						      General Commands Manual						       lp-shell(1)

NAME

       lp-shell - Open an interactive launchpadlib shell.

SYNOPSIS

       lp-shell [-a] [-cPROGRAM] [--python] [--ipython] [service] [LP API version]

DESCRIPTION

       lp-shell opens an interactive Python shell with a launchpadlib.Launchpad object "lp" which is ready for use.

       It  authenticates against Launchpad with the consumer name "udt-lp-shell". When using lp-shell with the -a option it will use the anonymous
       login from launchpadlib.Launchpad.

       By default lp-shell connects to the "production" Launchpad service using the "1.0" LP API version.

       If you want to connect to another Launchpad service, call lp-shell with the service name as the second argument. lp-shell supports all ser-
       vices known by launchpadlib Python module.  Currently known are (list can be incomplete or outdated): "production", "staging", "dogfood".

       A  different  LP  API version can be selected by passing the API version to use as the third argument. Current supported are: "beta", "1.0"
       and "devel".

OPTIONS

       -a     Login anonymously into Launchpad.

       -c PROGRAM
	      Don't enter a shell but only run the specified Python program and exit.

       --ipython
	      Use an ipython shell if available (default).

       --python
	      Use a regular python shell.
