enotes is a small GNU Emacs script to handle appointments. It stores a list of notes, each with a title, a date, a warning date, and optionally a long description and a reference file. A window pops up when a warning time is reached. It is simple (more than calendar and others), yet reliable and very practical.
selector is a command line utility for dynamic string selection. It reads the content of the specified files, and as the user types a list of strings separated by ";" (or a regexp), the display is updated in real time to show only the lines containing all the said strings (or matching the regexp). This command was mainly designed as a way to search in the shell history, for which it is substantially more efficient than the standard readline ^R binding. With the -v option, it injects the selected line into the tty input buffer, hence allowing the user to edit the line and execute it as a standard command.

The main usage of selector is as an efficient search in the shell command history. With the correct option, it will inject the selected line into the terminal input buffer, allowing the user to edit the line and execute it as a standard command.
