Elca (Extended Line Calculator) is a real-time Perl calculator (i.e., it evaluates expressions immediately as you type them). It supports hexadecimal, octal, and binary numbers, complex numbers, variables, string, list and hash operations, etc. It can convert expressions from human style to valid Perl code before evaluating them, and has a mechanism for importing external modules, allowing almost arbitrary extensions.

wtch periodically runs a shell command COMMAND and watches its output. When it changes it runs shell command ACTION. More precisely, it runs ACTION when a specified event occurs. The event can be a change of COMMAND's output, a change matching a certain pattern, or its negation, output equal to some previous output, etc. The output pattern defining an event is set by the --pattern option. By default, it simply detects any COMMAND output change.
