Hi RudiC, I am sorry my mistake, I was not clear up, so, look:

I have a directoy with files .CSV with names like this : ESTCOL_GPRS_201611*, these files are a lot, in the * are hour, Minute and seconds. The contents of these files are strings like these:

Code:
COMGPRS,CGHW12,COMGPRS_CGHW12_610617.dat,processed_cdr_20161117061743_01680861.cdr,20161117060116,20161117,225,42832

I wanna to count the unique occurrences for the column 2 and sum all of them and the values sum of column 8 to have an output like this:
Files Records
2,433 , 119,930,636


I have been trying something like this, but yet I have not achieved it

Code:
#!/bin/awk -f
BEGIN {
        FS=",";
}
{
        if (($1 == "COMGPRS") && ($2 == "ALK_01P")) {
                if (substr($5,1,8) == "20161115") {
                    sum+=$8;
                }
        }
}
END {
                print "Registros," $2 "," $sum;
}

I have not looked even count the number of files (Lineas unique)

sum(1)								   User Commands							    sum(1)

NAME

       sum - print checksum and block count for a file

SYNOPSIS

       sum [-r] [file...]

DESCRIPTION

       The   sum utility calculates and prints a 16-bit checksum for the named file and the number of 512-byte blocks in the file. It is typically
       used to look for bad spots, or to validate a file communicated over some transmission line.

OPTIONS

       The following options are supported:

       -r	Use an alternate (machine-dependent) algorithm in computing the checksum.

OPERANDS

       The following operands are supported:

       file	A path name of a file.	If no files are named, the standard input is used.

USAGE

       See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect  the	execution  of	sum:  LC_CTYPE,  LC_MESSAGES,  and
       NLSPATH.

EXIT STATUS

       The following exit values are returned.

       0	Successful completion.

       >0	An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWesu			   |
       |CSI			     |enabled			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       cksum(1), sum(1B), wc(1), attributes(5), environ(5), largefile(5)

DIAGNOSTICS

       "Read error" is indistinguishable from end of file on most devices; check the block count.

NOTES

       Portable applications should use cksum(1).

       sum and usr/ucb/sum (see sum(1B)) return different checksums.
