It is always very difficult for me to remember the time-table, especially for the first few weeks of semester. The condition was worse this semester, so I HAD to find a solution for this.I know, taking a photograph of the timetable would do it but I thought of doing something new (yeah!!)
Since, the start of this semester, I had started using Linux and so I thought of making a shell script to help me.Well, fortunately I stuck to this idea and hence after about an hour of Googling, I was able to learn enough of shell scripting to help me here.Well, to save u from even one hour of googling, I am sharing the skeleton of the program:
#! /bin/bash
if [ "$#" == "0" ]
then
set `date +%u`
if [ "$1" -eq "1" ]
then
echo -e "Monday's timetable\n"
else if [ "$1" -eq "2" ]
then
echo -e "\nTuesday\n"
else if [ "$1" -eq "3" ]
then
echo -e "\n Wednesday\n"
else if [ "$1" -eq "4" ]
then
echo -e "\n Thursday\n"
else if [ "$1" -eq "5" ]
then
echo -e "\nFriday\n"
fi
fi
fi
fi
fi
else
if [ "$1" == "1" ]
then
same thing again
fi
fi
So, why did I use $# here?
$# tells me the no of arguments passed. So if we passed a day number as an argument, then show that day's timetable, otherwise find the day of the week and then display the timetable.
why echo -e?
Normally, echo doesnot support escape sequences so we need to add -e for them.
and date +%u gives u the day of the week
We use the set command to give the value to the variable $1. $1 and all are special variables used in Shell script.
U can use == or -eq for checking the comparison. And it is visible that u need to end each if statement using fi!!
Anyways, now I have a shell script to tell me the timetable whenever I need it. Now all I need to do is make it autorun everyday in the morning and also turn it into a linux command. Will do that, and let u know :)
Enjoy this code till then. Yes, u are also welcome to tell me how to do the above!
