creating continuous calendar with bash

T3Q1la · 11-08-2019, 03:37 PM

Hello guys,

I started using Ubuntu recently and i wanned to write a little script, but i am not sure how to convert it into bash script.

I would like to display a monthly calendar using cal command. This should repeate as often as desired for different years and month till the user likes to exit the process. As soon as that happens the user has to be given an echo how to stop the prozess.

Do you have any idea how to write it as script? Please let me know, many thanks in advance!

Can you clarify the input and the output of your desired program? I.e. how does the user tell the program what they want.

A possible solution without writing a program: To output a certain month and year, for example December 2019, the user can just type cal 12 2019. When they want another month, they type cal anothermonth anotheryear. When they want to exit the process, they stop typing.

sounds like a learning curve. start with simple loops, and build up into how to break out of them, stop them from running, echo and read -p "text" var

Here's a freebe

Code:

#!/usr/bin/env bash
var=y
while [[ ${var^^} != 'N' ]] 
do
    read -p "enter month and year, mm/yyyy " date
    cal $date
    read -p "do you want to continue? Y/n " var
done
