Thank you DGPickett for your answer but what I need is to modify the given code to obtain the intersection results for 4 and 5 or more files than just 3.
Actually, I want this kind of result:
records found in 3 files:
.
.
.
.
records found in 4 files:
.
.
.
.
.
records found in 5 files:
.
.
.
records found in 'n' files:
but the program now is only showing this:
records found in 3 files:
I hope this would clarify any doubts

SYNOPSIS

[options]
DESCRIPTION
The command converts a sequence of login/logoff records read from its standard input to a sequence of records, one per login session. Its
input should normally be redirected from or Its output is ASCII, giving device, user ID, login name, prime connect time (seconds), non-
prime connect time (seconds), session starting time (numeric), and starting date and time. Prime connect time is defined as the connect
time within a specific prime period on a non-holiday weekday (Monday through Friday). The starting and ending time of the prime period and
the year's holidays are defined in file
expects as input a sequence of login session records, produced by and converts them into total accounting records (see format in acct(4)).
combines the functionality of and into one program. It takes the same input format as and writes the same output as
recognizes the following options:
Print input only, showing line name, login name,
and time (in both numeric and date/time formats).
maintains a list of lines on which users are logged in.
When it reaches the end of its input, it emits a session record for each line that still appears to be active. It
normally assumes that its input is a current file, so that it uses the current time as the ending time for each ses-
sion still in progress. The flag causes it to use, instead, the last time found in its input, thus ensuring reason-
able and repeatable numbers for non-current files.
and recognize the following options:
file is created to contain a summary of line usage showing line name, number of minutes used, percentage of total elapsed
time used, number of sessions charged, number of logins, and number of logoffs. This file helps track line usage,
identify bad lines, and find software and hardware oddities. Hang-up, termination of (see login(1)), and termination
of the login shell each generate logoff records, so that the number of logoffs is often three to four times the num-
ber of sessions. See init(1M) and utmp(4).
file is filled with an overall record for the accounting period, giving starting time, ending time, number of reboots, and
number of date changes.
When this option is used, the records of the type found in
are read from the specified input.
