The third video (following the announcement, the shell colors) one as well as last week\u2019s shell prompt one, is up in the stil new T^4 series of video lightning talks with tips, tricks, tools, and toys. Today we cover customizing the shell some more. The slides are here. This repo at GitHub support the series: use it to open issues for comments, criticism, suggestions, or feedback. If you like this or other open-source work I do, you can now sponsor me at GitHub. For the first year, GitHub will match your contributions.
