Sum up values of columns in 4 files using shell script
I am new to shell script.I have records like below in 4 different files which have about 10000 records each, all records unique and sorted based on column 2.
I want to get column 2 of each file and sum up column 4 of each file and the whole process should not take more than 15-30 min. So my output should be a different file with records as below.
Can someone help me with this

ac
ac(8) System Manager's Manual ac(8)NAME
ac - Outputs connect-session records
SYNOPSIS
ac [-dp] [-w filename] [user(s) ...]
FLAGS
Outputs the total connect time for each midnight-to-midnight period for which a wtmp file exists. When user(s) is specified, this flag lim-
its the output to the login names specified by any user(s) parameter(s). Outputs the connect time total by individual login name of the
user specified with the -p flag and the user(s) parameter. Omission of this flag permits a total only for the midnight-to-midnight time
period for all logged in users to be produced. Specifies a wtmp file other than the /var/adm/wtmp file. The wtmp file you access for data
may have been created automatically by some shell script administration command (for example, runacct) or manually by the system adminis-
trator when the original /var/adm/wtmp file becomes too large.
DESCRIPTION
The ac command prints to the default output device the total connect time in hours to the nearest hundredth for all users, or the connect
time for any user(s) specified with the -p flag. It also prints the names of users specified by the user(s) parameter who have logged in
during the life of the current /var/adm/wtmp file.
Connect-time records are written by the init and the login programs and are collected in the /var/adm/wtmp file, when such a file exists.
When a /var/adm/wtmp file does not exist, no connect-time accounting records are written; consequently, when connect-time records are
wanted, the system administrator should create a /var/adm/wtmp file that has an initial record length of 0 (zero). Records in wtmp files
(there may be more than one such file) should be processed periodically to keep the files from becoming too large.
When you use the runacct command in a shell script, additional wtmp files can be automatically created whenever the current wtmp file
becomes too large. You can output the contents of any of these other files when you specify the -w flag and the desired wtmp filename.
The ac command is run independently with respect to any accounting shell procedure created or run by any of the acct/* shell procedures or
runacct commands.
EXAMPLES
To obtain an output of the total connect time for all users who have logged in during the life of the current wtmp data file, enter:
/usr/sbin/ac To obtain an output of the total connect time for grossman and mcwhinney as recorded in the default wtmp data file,
enter:
/usr/sbin/ac grossman mcwhinney To obtain an output of the connect time subtotals for grossman and mcwhinney as recorded in the
default wtmp data file, enter:
/usr/sbin/ac -p grossman mcwhinney
FILES
Specifies the command path. Is the active data file for the collection of connect-time records.
