This is a small Terminal Timer utility script that counts down hours, minutes and seconds. It prints the remaining time using figlet every second and alerts when 0 has been reached.

For a very neutral timer, pass -p 1.

$ bash tertletimer.sh -a "23:30:00" -p 1
04:35:48

Caveat: depending on your terminal setup it may or may not be able to trigger sound! You may need to add a line to do this...

Usage:

tertletimer

start a timer that counts down from the specified time.

Options:

• -h hours
• -m minutes
• -s seconds
• -p print style (font)
• -a absolute time at which to alert. Format: "2020-05-25 11:30:00". needs gnudate.

You should only pass either hours/minutes/seconds OR an absolute date.

I added the line to my ~/.bash_profile to make the script globally accessible:

alias tertle="~/tertletimer/tertletimer.sh"

Requirements

• figlet (and fonts, if you want to use the fancy print options. Otherwise pass -p 1)
• gdate (if you want to use the absolute date option)

Example

bash tertletimer -m 5 -s 30

-> will count down 5 minutes and 30 seconds

bash tertletimer -a "19:30"

-> to 7:30 PM the same day.
