Hi Skrynesaver,

many many thanks for your BIG HELP.

Impressive job, really!

I launched your script and here his output:

Code:
WORD,TOTFrequency,(1)Frequency,(0)Frequency,(-1)Frequency,1%Frequency,0%Frequency,-1%Frequency
that,20,11,1,80.43%,0.02%,0.17%
great,1,1,0,00.02%,0.00%,0.00%
really,9,5,2,20.19%,0.04%,0.04%
day,1,1,0,00.02%,0.00%,0.00%

So, I'd like to ask you about 4 points:

1) As you can see the FIELD "(-1)Frequency" is not present
2) Words column is not sort in decreasing order
3) Is possible to set an option to search words "like grep -i" case insensitive in order to match as follows:

Code:
my @wanted=qw(day) result= today days monday etc.......

4) Is possible to search "like grep -i" case insensitive and list in decreasing order the 50 most frequent words, where words >=3 characters?


Again, many many thanks for your attention and for your BIG HELP.

Hope to hear from you soon!!!!

Have a good time.

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
