i needed a way to set a reminder on my debian system so that i don't forget to attend meetings, since i don't have access to my online calendar. so after some googling, i've found a solution using the at command and zenity dialog.
"at" lets one execute a command at a specific date and time in the future. there are quite a few options.
zenity is a package that provides and easy way to pop-up a custom dialog box. there are quite a few options for zenity as well.
open a terminal, for an event at 9:00am on October 29 enter the following:
at 0900 Oct 29
a "at>" prompt will appear. enter the command to execute:
at> env DISPLAY=:0.0 zenity --info --title "my title" --text "my custom message"
when finished with the command hit the enter key, then press CTRL-D. a job number with date and time for the job will appear.
specify the display device to use for the zenity dialog
env DISPLAY=:0.0
specify a zenity info dialog box
--info
specify the zenity dialog box title
--title "my title"
specify the zenity dialog box message text
--text "my custom message"
info take from:
man page for at command
man page for X
