  When combined with standard command-line utilities for text processing, Telepipe’s clipboard redirection grants the capability to easily use advanced text editing even in text editors or other software applications lacking sophisticated features for modifying text. Telepipe makes it easy to copy text, pipe it into a shell command pipeline, and paste the result wherever it’s needed.
