28. Juni 2025 in Administration, GNU/Linux, Programmierung.
I am using the terminal a lot on Linux. For my project „pulseaudio-tcp“ (see here for more information) i wanted to have more comfortable command line completion in Bourne Again Shell („Bash“). After having typed in the command name pulseaudio-tcp, when pressing the Tabulator key, i would like to see a list of all possible arguments to that command.
In this article i demonstrate how to leverage the „Programmable Completion“ feature of Bash for such purposes. A reasonably recent version of Bash (4.2 or later) is assumed.

In the article, we will make use of some advanced Bash features such as array expansion with pattern matching; these will be explained „on the go“ as required.
