| # dontforget | |
| # Description: A stupid script for short term reminders in bash | |
| # Requires: espeak, mpg123, notify-send, ogg123 (vorbis-tools) | |
| # Source: http://brettterpstra.com/2016/01/22/quick-reminders-from-terminal | |
| # Usage: | |
| # | |
| # Arguments just need to contain a number and a bunch of words. | |
| # | |
| # The number can be anywhere in the arguments, but there shouldn't | |
| # be any other numeric digits. | |
| # | |
| # If the number has h, m, or s immediately after it (no space), it will | |
| # be interpreted as hours, minutes, or seconds. The default assumption | |
| # is minutes. | |
| # | |
| # Save the script as `dontforget` in your path and make it executable | |
| # | |
| # Example usage: | |
| # $ dontforget let the dog back inside 10 | |
| # => I'll remind you: "let the dog back inside" in 10 minutes | |
| # | |
| # It can parse a little extra verbosity around the text, too | |
| # $ dontforget to let my dog back in 10m | |
| # => I'll remind you: "let your dog back in" in 10 minutes | |
| # | |
| # $ dontforget I really need to take a break in 1h | |
| # I'll remind you: "you really need to take a break" in 60 minutes | |
| # | |
| # Running dontforget with no arguments will list upcoming reminders | |
| # | |
| # Use `dontforget cancel` or `dontforget nevermind` to cancel the last | |
| # reminder that was created | |
| # | |
| # $ dontforget cancel | |
| # Canceled "you really need to take a break" | |
| # | |
| # To turn on desktop notification | |
| # export DF_NOTIFY=true | |
| # | |
| # To make dontforget remain in the foreground and cancelable with ^c | |
| # export DF_NO_BACKGROUND=true | |
| # | |
| # Tip: | |
| # alias forget="dontforget cancel" | |
