For Fun: Have a Unix time party

mmatt · 01-29-2009, 01:40 PM

Hi there. I didn't really know where to put this exactly, just sharing with the world, looking for improvements...

You may not have realised (though you probably have) that unix time 1234567890 (seconds since the epoch) is nearly upon us. This is a small script which counts down the seconds to this event.

Code:

#!/bin/bash
# unixparty - a countdown script

secs=$[1234567890-`date +%s`]

while [ $secs -gt 0 ]
do
clear

echo
echo " Seconds until UNIX time 1234567890"
echo

secs=$[1234567890-`date +%s`]
echo "     seconds: $secs"
mins=$[$secs/60]
echo "     minutes: $mins"
hrs=$[$mins/60]
echo "     hours:   $hrs"
days=$[$hrs/24]
echo "     days:    $days"
sleep 1
done
echo
echo
echo "     HAPPY UNIX 1234567890 second!!!"
echo
echo

My question? Can anyone improve upon this since it has a number of shortfalls.
1) It scrolls using the clear command
2) The sleep mechanism isn't entirely reliable (appears to hang for ~2 secs).

I look forward to hearing your replies, though I'm sorry if you've read this and feel I've wasted your time! (It is perhaps a bit purile!)

not sure what the significance is, but here is an improvement to your script:

Code:

clear
while [ $secs -gt 0 ]
do
   tput cup 0 0

HA! 1234567890 is on the day of my brothers birthday! He's about the most incompetent computer user there is though.

Thanks crabboy, I'll give that a try. Planning on having it on a big screen in the lab perhaps.

Code:

#!/bin/bash

OMG=1234567890

T=`date +%s`
if [ $T -ge $OMG ]
then
    echo "Too late."
    exit 1
fi

trap "printf \"\r\"; echo \"Awww, booo!                              \"; exit 2" SIGINT SIGHUP

S=2
while [ $S -gt 1 ]
do
    T=`date +%s`
    S=$(($OMG-$T))
    M=$(($S/60))
    H=$(($M/60))
    D=$(($H/24))
    SL=$(($S-$M*60))
    ML=$(($M-$H*60))
    HL=$(($H-$D*24))
    DL=$D
    printf "\r                                         "
    printf "\r$DL days, $HL hours, $ML minutes, $SL seconds"
    sleep 1
done

printf "\r"
echo "Wooooooooo!                              "

Even if it was for frivilous purposes, I've learnt new and useful ways of showing output on the command line so thanks for the feedback!

Unix time is a system for describing points in time, defined as the number of seconds elapsed since midnight proleptic Coordinated Universal Time not counting leap seconds. It is used widely, not only in Unix like operating systems, but also in many other computing systems and file formats.

What is your point? And why drag up a post that is nearly 2 years old?

Odds on they're about to start spamming LQ...
