Write a script using a Linux shell programming language to perform clock management for a small daycare.
The program should manage all time in and out routines. At the end of the each day should give the Total hours worked that day.
Example:
Code:
Time-In 6:30am
Lunch-Out 11 :25am
Lunch-In 11:40pm
Time-Out 5:30pm
Total Hours Worked =
I have no clue where to start. I tried take in the user's input for IN/OUT Time, but then I'm not sure how to parse it to calculate the total hours. Not sure if there is another approach for this.

Please use code tags for samples, as per forum rules.
This appears to be homework.

That sounds like an assignment given to a student.

Dear Folks,
I want to calculate the elapsed hours between two time columns. I am using timestampdiff method for the same. I am able to get the value. But facing an issue of decimal values. For example the elapsed hours between 09:00:00 and 20:30:00 is coming as 11 instead of 11.5. I am using below... (1 Reply)
Hi Experts,
In a particular dir, I have many files *AJAY*.
How can I get total size of all such files.
I tried du -hs *AJAY* but it gave me individual size of all files.
All I require is summation of all.
Thanks,

acctprc(8) System Manager's Manual acctprc(8)NAME
acctprc1, acctprc2, accton - Perform process-accounting procedures
SYNOPSIS
acctprc1 [InFile]
acctprc2
accton [OutFile]
DESCRIPTION
The three acctprc commands, acctprc1, acctprc2, and accton, are used in the runacct shell procedure to produce process-accounting reports.
acctprc1 [InFile]
The acctprc1 command is used to read records from standard input that are in a format defined by the acct structure in the
/usr/include/sys/acct.h header file. This process adds the login names that correspond to user IDs, and then writes corresponding ASCII
records to standard output. For each process, the record format includes the following seven unheaded columns: The user ID column includes
both traditional and assigned user identification numbers listed in the /etc/passwd file. The login name is the one used for the user ID
in the /etc/passwd file. The number of seconds the process consumed when executed during prime-time hours. Prime-time and nonprime-time
hours are defined in the /usr/sbin/acct/holidays file. The number of seconds the process consumed when executed during nonprime-time
hours. Total number of characters transferred. Total number of blocks read and written. Mean memory size (in kilobyte units).
When specified, InFile contains a list of login sessions in a format defined by the utmp structure in the /usr/include/utmp.h header file.
The login session records are sorted according to user ID and login name. When InFile is not specified, acctprc1 gets login names from the
password file /etc/passwd. The information in InFile is used to distinguish different login names that share the same user ID.
acctprc2
The acctprc2 command reads, from standard input, the records written by acctprc1, summarizes them according to user ID and name, and writes
sorted summaries to standard output as total accounting records in the tacct format (see the acctmerg command).
accton [OutFile]
When no parameters are specified with the accton command, account processing is turned off. When you specify an existing OutFile file,
process accounting is turned on, and the kernel adds records to that file. You must specify an Outfile to start process accounting. Many
shell script procedures expect the file name /var/adm/pacct, the standard process-accounting file.
EXAMPLES
To add a user name to each process-accounting record in a binary file and then write these modified binary-file records to an ASCII file
named out.file, enter the following line to an accounting shell script:
/usr/sbin/acct/acctprc1 < /var/adm/pacct >out.file
A user name is added to each record. The raw data in the pacct file is converted to ASCII and added to file out.file. To produce a
total binary accounting record of the ASCII output file out.file produced in example 1, enter the following line to an accounting
shell script:
/usr/sbin/acct/acctprc2 < out.file > /var/adm/acct/nite/daytacct
The resulting binary total accounting file, written in the acct format, contains records sorted by user ID. This sorted user ID
file, is usually merged with other total accounting records when an acctmerg command is processed to produce a daily summary
accounting record called /var/adm/acct/sum/daytacct. To turn on process accounting, enter:
/usr/sbin/acct/accton /var/adm/pacct To turn off process accounting, enter:
/usr/sbin/acct/accton
