1) try a space between -v and W= (some awks require it)

2) I think I misunderstood your requirement try:
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,NV"
  for (w in counts) printf ("%s,%d,%d,%d,%d,%0.1f%%,%0.1f%%,%0.1f%%,%0.2f\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],
         (0+freq[1,w]+freq[-1,w])?
         freq[1,w]-freq[0,1]/(freq[1,w]+freq[-1,w]):0) | "sort -t, -k2,2nr -k1,1"
}
'  infile

Hi Hi Chubler_XL,

many thanks for your help,

this is exactly what I need, but there is an error:


Code:
awk: syntax error at source line 23
 context is
	         (0+freq[1,w]+freq[-1,w])? >>> 
 <<<          freq[1,w]-freq[0,1]/(freq[1,w]+freq[-1,w]):0) | "sort -t, -k2,2nr -k1,1"
awk: illegal statement at source line 24

Many thanks for your big help

Works OK here, could be the newline try joining line 23 and 24 into one like this:

Code:
(0+freq[1,w]+freq[-1,w])?freq[1,w]-freq[0,1]/(freq[1,w]+freq[-1,w]):0) | "sort -t, -k2,2nr -k1,1"

or putting a backslash on the end of line 23 like this:
Code:
(0+freq[1,w]+freq[-1,w])?\
freq[1,w]-freq[0,1]/(freq[1,w]+freq[-1,w]):0) | "sort -t, -k2,2nr -k1,1"

Hi Chubler_XL,

you are great!!!

Last thing, how can i set here:

Code:
#!/bin/bash
awk -F, -v W="day,really" '
BEGIN { split(W,w,",") ; for(i in w) N[w[i]]}
{ for(word in N) if ($1 ~ word) for(i=2;i<=NF;i++) v[word,i]+=$i }
END {
   for(word in N) {
       printf "%s", word
       for(i=2; word SUBSEP i in v; i++)
           printf ",%s", v[word,i] ((i==7||i==9||i==11)?"%":"")
       printf "\n"
   }
}'

just the first occurrence in each analyzed line ?

There are some duplicates in terms of final value!

Itīs possible that the same word appears in the same line more times, and i need to calculate it just one time!


Many thanks for your big help!!

your code used as follows:

Code:
./script.sh | head -100 > outfile

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,NV"
  for (w in counts) printf ("%s,%d,%d,%d,%d,%0.1f%%,%0.1f%%,%0.1f%%,%0.2f\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],
         (0+freq[1,w]+freq[-1,w])?\
         freq[1,w]-freq[0,1]/(freq[1,w]+freq[-1,w]):0) | "sort -t, -k2,2nr -k1,1"
}
'  infile

Here you can see his output:

Code:

iamrealltyga,20,20,0,0,100.0%,0.0%,0.0%,20.00

the value NV should be a number between -1 and 1

it seems strange, do you have any ideas?

thanks for your attention

Looks like we are missing some brackets replace:
Code:
freq[1,w]-freq[0,1]/(freq[1,w]+freq[-1,w]):0) | "sort -t, -k2,2nr -k1,1"

with

Code:
(freq[1,w]-freq[0,1])/(freq[1,w]+freq[-1,w]):0) | "sort -t, -k2,2nr -k1,1"
