Question

I need to create a shell script that will remind the employees to fill n their timecards at the end of each day using variables to define the names of all the employees - I could really use some help!

Answer 1

The shell script to remind the employees to fill their timecards at the end of the day is shown below and executed:

CODE:

Input file employees.dat containing employee name. For any new employee we can add employee name here.

Unix Terminal> cat employees.dat

Ravi Kishan

Roshan Kumar

Robert Lafore

Henry Herbert

Dennis Raid

Unix Terminal>

Code:

Unix Terminal> cat remind_emp.sh

#!/bin/bash

# timesheet file to log the logout time of an employee

timesheet='/tmp/emp_timesheet.dat'

# input file employees.dat containing employee names

emp='employees.dat'

# if /tmp/emp_timesheet.dat file already exist zero the contents of file

test -e $timesheet && cat /dev/null > $timesheet

IFS=$'\n'

# iterating through each employee in employees file

for each_emp in `cat $emp`

do

# getting employee log out time

echo "Enter the log out time of ${each_emp}: "

read log_time

# writing employee name and log out time to the timesheet file

echo "$each_emp $log_time">>$timesheet

done

echo "Log out time of all the employees recorded..."

Unix Terminal>

OUTPUT:

Unix Terminal> bash remind_emp.sh Enter the log out time of Ravi Kishan: 5pm Enter the log out time of Roshan Kuman: 6pm Enter the log out time of Robert Lafore: 7pm Enter the log out time of Henry Herbert: 8pm Enter the log out time of Dennis Raid: 8.30pm Log out time of all the employees recorded...
