Tech Tip: Get Notifications from Your Scripts with notify-send

In file "alarmclock":

#!/bin/bash
echo "Usage: 15:30 for 3:30 PM, times assumed to be before midnight."
echo "Use atq and atrm to halt notifications."

DATESTRING="`date --rfc-3339=date | sed 's/-//g '`"
TIMESTRING="`echo $1 | tr -d ":" `"
ALARMSTRING="$DATESTRING$TIMESTRING"
at -t $ALARMSTRING -f ~/bin/alarmclock.sh

In file alarmclock.sh:
#!/bin/bash
j=0

while [ $((j++)) -lt 10 ]
do
  notify-send "Leave now" -t 5000 -u critical
  sleep 1m
done 

How it works:

Use atq and atrm to halt notifications.

Pops-up 10 notifications at the desired time as desired. Now if I could just get the window center and larger . . . maybe have to write some C to call X functions, or figure out how to call libnotify with different args? Thanks, Kristofer, for the excellent tip.

I was making a weather popup -- I work in a sub-basement and always want to know what things look like when I go up to ground level -- and I wanted to stick the degree symbol (°) with Unicode and got a circumflex capital A (°) first. Any idea. When I print the string to STDOUT, no problem. When it goes to notify, no dice. Perl, btw. Is there a Unicode-safe way of handling this?

I like osd_cat best myself.

Hello,

Can I send a Pop-Up Notification to another PC with UBUNTU system.

Thanks a Lot.

Jonathan.
