Automatic Appointment

[Jesca Hagaze]

I created this shell script so that it will remind/ give an alert all users From Monday - Friday at 8:15 that "Good Morning".

#!/bin/bash
#
Take input()
{
appointment=0
clear
echo "Daily Appointment"
read appointment
if [! -f $appointment]; then
echo "Appointment does not exists, creating $appointment database"
echo "Appointment Application database file" > $appointment
fi
echo "Start reading Appointment schedule" > /etc/schedular.$$
while:
do
echo -n "Good Morning"
read na
echo -n "8:15"
read ti
echo -n "is data okey (y/n)?"
read ans
if [$ans=y -o $ans=Y]; then
recno = "expr $recno + 1
echo "$rechno. $na $ti" >> /etc/schedular.$$
fi
done
}

Is this the right way to write a shell script?, what can I do to make it work properly.
Thank you for your respons and be blessed.

I am new to Linux, I am learning shell scripts.
I wrote another shell script which will alert/ give message from Monday to Friday(5 weekdays) at 8:15 that "Welcome to Work Place"

#!bin/bash
HOUR='date | grep {'echo $4'}'
MINUTE='date |grep {'grep $5'}'
DAY='date | grep ('cal[Mon - Fri]')'
while true; do
if [$HOUR -eq 8] -a [$MINUTE -eq 15]; then
echo $DAY "Welcome to work place"
else
sleep 13500s
fi
done

I got the error message that /date command not found on line 2, 3 and line 4.
I need your assistance and be blessed.

When you are setting a variable equal to the output of a command, the command must be surrounded by back ticks ` not single quotes '
