- das-shell 0.3.0: aliases and functions for every interactive bash (/usr/share/das/shell, loaded by /etc/bash/bashrc.d/das-aliases.sh, then the user's ~/.bash_aliases and ~/.bash_functions; off with ~/.config/das/no-aliases). Based on the author's own set, adapted to Void (xbps, nftables, das-update), with fixes (rmhost, netinfo, todo -r, dirsize, extract) and new ones (up, bigfiles, pkgowner, please, serve, weather, cheat, genpass, Docker shortcuts). lsfunc shows bilingual descriptions. Shell tests in tests/test_shell.py. - Names that shadowed commands are gone: gh -> hgrep, mount -> mounts, no install or ed. - README: "Aliases and functions" section; TODO: banner, dashboard service and prompt verified by the author on real hardware.
