Writing shells script to display time in am or pm notation

Question

I'm trying to write a shell script that displays the time in am or pm rather than the way it is shown using date command. I'm not sure how I should go about doing this. I guess for starters, how do I extract the time from the date command to manipulate it? And how do I extract the number for the hour to manipulate it?

Answer 1

You can use below one to print time in AM and PM format up to minutes.

echo $(date  +"%I:%M %p")

OutPut: 09:20 PM

or

echo $(date  +"%r")

Output: 09:20:09 PM

or echo $(date +"%I %p")

Output: 09 PM
