distinct values of all the fields
I am a beginner to scripting, please help me in this regard.

How do I create a script that provides a count of distinct values of all the fields in the pipe delimited file ? I have 20 different files with multiple columns in each file. I needed to write a generic script where I give the number of columns as a parameter to the script or the script by itself should be able to recognize the number of columns in the file based on the delimiter. The script needs to generate the output as below.

Sample data

Field1|Field2|Field3|Field4
AAA|BBB|CCC|DDD
111|222|333|777
AAA|EEE|ZZZ|EEE
111|555|333|444
AAA|EEE|CCC|DDD
111|222|555|444

For the above file, the result I am looking for would be:

Field1
AAA(3)
111(3)

Field2
BBB(1)
222(2)
EEE(2)
555(1)

Field3
ccc(2)
333(2)
zzz(1)
555(1)

Field4
DDD(2)
777(1)
EEE(1)
444(2)

Thank you in advance for your assistance.

jdbreg

jdbreg(8)						      System Manager's Manual							 jdbreg(8)

NAME

       jdbreg - Registers hosts in the DHCP dynamic databases.

SYNOPSIS

       /usr/sbin/jdbreg [-d] [-e] [-f character] [-s] [-l  | -n] [-o] [-w] filename...

OPTIONS

       Deletes the records whose keys are implied by the input file(s).  Uses character as the field separator.  The default is the pipe | charac-
       ter.  Display all currently registered hosts.

DESCRIPTION

       The jdbreg program registers (or removes) hosts for configuration by DHCP.  When the registered_hosts_only policy is in effect, the  server
       configure only clients whose MAC addresses are so registered. When this policy is not in effect, registering hosts has no effect.

       Each  record  to  be loaded is terminated by a newline, and the fields within each record delimited by default with the pipe (|) character,
       although this may be changed with the -f command line option.

       The fields within the data file(s) to be loaded are as follows: MAC address MAC address type MAC address length (octets)

RESTRICTIONS

       Because the database used by join does not support multiuser concurrently, applications that write to it, lock the entire  database.   This
       means that you cannot use jdbreg while joind is running. The converse is also true.
