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:
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.

Dear Folks,

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,

Time::JulianDay(3pm) User Contributed Perl Documentation Time::JulianDay(3pm)NAME
Time::JulianDay -- Julian calendar manipulations
SYNOPSIS
use Time::JulianDay
$jd = julian_day($year, $month_1_to_12, $day)
$jd = local_julian_day($seconds_since_1970);
$jd = gm_julian_day($seconds_since_1970);
($year, $month_1_to_12, $day) = inverse_julian_day($jd)
$dow = day_of_week($jd)
print (Sun,Mon,Tue,Wed,Thu,Fri,Sat)[$dow];
$seconds_since_jan_1_1970 = jd_secondslocal($jd, $hour, $min, $sec)
$seconds_since_jan_1_1970 = jd_secondsgm($jd, $hour, $min, $sec)
$seconds_since_jan_1_1970 = jd_timelocal($sec,$min,$hours,$mday,$month_0_to_11,$year)
$seconds_since_jan_1_1970 = jd_timegm($sec,$min,$hours,$mday,$month_0_to_11,$year)
DESCRIPTION
JulianDay is a package that manipulates dates as number of days since some time a long time ago. It's easy to add and subtract time using
julian days...
The day_of_week returned by day_of_week() is 0 for Sunday, and 6 for Saturday and everything else is in between.
ERRATA
Time::JulianDay is not a correct implementation. There are two problems. The first problem is that Time::JulianDay only works with
integers. Julian Day can be fractional to represent time within a day. If you call inverse_julian_day() with a non-integer time, it will
often give you an incorrect result.
The second problem is that Julian Days start at noon rather than midnight. The julian_day() function returns results that are too large by
0.5.
What to do about these problems is currently open for debate. I'm tempted to leave the current functions alone and add a second set with
more accurate behavior.
There is another implementation in Astro::Time that may be more accurate.
