Question Help with date command in bash shell programming

Doubt #1
I have a program that I want the user to input date. When the user inputs the date, is it able to format it to system date dd-mm-yyy and then echo the value into a text file?

Doubt#2
If the above is not going to work, I tried to have the system date appear in the user input field and when the user enters to continue, the date shown can be echoed into a text file? The date command that I used is "date +%d-%m-%y".

My codes are something lk this:
Code:
echo -en "Date Purchased: "
read datePurchased
echo "${datePurchased} >> a.txt

Please do help me if you know of a way as I just started learning bash shell programming and its really difficult!! Smilie

Thanks in advance !

The user are free to type in any format but it is advisable to type in "ddmmyyyy". I think there needs to be a function or some lines of code to format the user input date to be similar to the system date.Smilie

You can use zenity to input a date in a graphical box with the --calendar switch. Users like graphical boxes and zenity does a very nice job of extending the possibilities of shell scripts.
