CLI World Clock mini script

[Member PPC]

I was looking to adapt a nice little GUI World Clock to include in my FT10. I still have not created such a script, but I managed to create a nice little one that Works in the terminal.
-Copy the text below to a text document called something like “world-clock.sh” and save it
-make sure the script is executable
-run the script from the terminal

Note: the script automatically creates the needed config file, that can be edited, and includes all needed instructions.

#!/bin/bash
# Command-line world clock by PPC 9/1/2022, GPL license
#Adapted from https://gist.github.com/rangersmyth74/4c7e291b64d48c1beb7029e9b07b6bca
#and from examples over at stackoverflow like over at https://stackoverflow.com/questions/370075/command-line-world-clock

# create preference file $HOME/.world-clock.zones, if it's missing
if [ ! -f $HOME/.world-clock.zones ]; then
echo "Europe/London
Europe/Paris
Asia/Tokyo
America/St_Johns
Brazil/West
" > $HOME/.world-clock.zones
fi

: ${WORLDCLOCK_ZONES:=$HOME/.world-clock.zones}
: ${WORLDCLOCK_FORMAT:='+%Y-%m-%d %H:%M:%S %Z'}

function world-clock ()
{
echo
echo "		CLI World Clock:"
echo

while read zone
do echo $zone '!' $(TZ=$zone date "$WORLDCLOCK_FORMAT")
done < $WORLDCLOCK_ZONES |
awk -F '!' '{ printf "%-20s  %s\n", $1, $2;}' |
sort -b -r -k2,2 -k3,3
echo
echo "You can manage the displayed time zones by editing the file $HOME/.world-clock.zones"
echo "The list of all available time zones, in English, is available at https://en.wikipedia.org/wiki/List_of_tz_database_time_zones"
echo
echo "Press Ctrl + C to exit"
}

export -f world-clock
clear

while true;
do
	world-clock;
	sleep 1;
	clear
done

Enjoy

I agree, very cool! I changed the London time to America/New-York and kept the others intact, so I have several, including UTC, which I believe is the same as London time anyway. Works great!

Love this:) Thinking about adding a right-click option in Lilidog for this. Good stuff. My wife and I are always trying to remember time zones of folks we know.

Thanks, everyone!

I have a slightly updated version, that also shows local time (I noticed I was always looking at my toolbar to see what time it was here). Also I shortned the instructions, to make them more practical, and removed the empty final line that crept into the config file:

@sleekmason – nice plug for your build! Myself, I find antiX full, with my FT10 transformation pack perfect in every single device I tested (from an 32bits/1Gig of RAM laptop to my quad-core, 4Gig desktop)

@PPC
Not plugging anything, but thanks. If I were, I would just make announcements. In fact, I have not even updated the original announcement I made in the section designed for such purposes even though it has gone through drastic changes.

It seems I have made an error in how freely I can write/think. I certainly won’t discuss Lilidog or anything related anymore and I will remove access to “My build” in my signature. Sorry if I offended anyone by providing the link.

I’ve used antiX since it’s inception, and it is one of two distros I regularly depend on for good advice. I’ve no doubt it runs well on everything you have.

@sleekmason – You missunderstood me! I was happy to see the screenshots from another tinkerer like me!
Now and then I mention my FT10 transformation pack in other threads, other than the official one, when I think it makes sense. you simply said you were thinking about adding this script to your distro, I’m even flatered!

Would it be possible to change out Ctrl +C? to exit with something like:

echo $'\n\nPress any key to close.'; read -srn1

My thinking is to put it as a right-click option on the panel clock, with a simple ‘Press any key to close’.

My brilliant scripting ability of replace it until it works, didn’t. 🙂

@sleekmason, I don’t think you have to worry about plugging your builds. I’m not an admin here, and Brian or others will correct me if I am wrong, but we did not take any offense. We are all tinkerers and are often interested in what others are doing to modify their systems. A casual mention of a project in context is not a problem.

Sure, I poked around some examples on-line and adapted the script- it now runs on even fewer resources and you can press any key (or the middle mouse button) to exit:

}

export -f worldtz
watch -t -n 1 -x bash -c worldtz  &   # put function in the background
read -n 1
kill $!               # kill the the job most recently placed into the background
read -t 0.1 -n 1000000

You’re right. Simple mention of another distribution is fine; we even have a section to discuss experience with variations or rebuilds and reviews.

That would be a good place to discuss other things.
