- 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.

- The installed system runs `sshd`, `chronyd`, `nftables`, `fail2ban`, `docker`, `socklog` and the chosen network service.
|
||||
- nftables lets in only SSH, ICMP and DHCPv6 (`/etc/nftables.conf`), more ports are opened with `dfw`. The rules live in their own table `inet das`, so reloading them keeps the Docker and fail2ban rules. Ports that containers publish pass through Docker's own rules.
|
||||
- fail2ban bans addresses that keep failing SSH logins, reading the socklog log. sshd doesn't accept root password logins.

- Quick widgets run at login with a short timeout. Slow or root-only ones (updates, weather, SMART, fail2ban) are refreshed by the `das-banner` runit service into `/var/cache/das/banner`, and `dbanner apply` enables it when a banner needs it. No cron is needed.
|
||||
- Drafts are kept in `~/.config/das/banner`; Ctrl+A or `dbanner apply NAME` writes `/etc/das/banner.json` through sudo. `dbanner off` and `on` turn the banner off for everyone, `~/.hushlogin` for one user; `"local": true` shows it on console logins too.

**_Ready shortcuts for everyday terminal work in every interactive bash, rewritten for Void: xbps, nftables, runit and Docker._**

- They come from `/etc/bash/bashrc.d/das-aliases.sh` (package `das-shell`): `/usr/share/das/shell/aliases.sh` and `functions.sh`, then your own `~/.bash_aliases` and `~/.bash_functions`, which win. `touch ~/.config/das/no-aliases` turns the Das OS ones off for one user. `lsfunc` lists the functions with a description in the user's language, `alias` lists the aliases.
|
||||
- `ls`: `ll`, `la`, `l`, `sl`, `lsl` (in `less`), `lsz` (by size), `lst` (by time), `lsd` (directories only); `grep`, `diff` and `ip` in colour.
|
||||
- Directories: `..`, `...`, `....`, `cd..`, `up [N]` (N levels up), `mkcd DIR` (create and enter), `cl DIR` (enter and list), `path` (one `PATH` entry per line); `mkdir` makes parents.
|
||||
- Files: `f PATTERN [DIR]` (find by name, any case), `fhere NAME`, `cnt` (number of files), `bigfiles [DIR] [N]`, `dirsize [DIR]` (sizes of everything in a directory), `whatsize [DIR]` (subdirectory sizes, `/` by default), `bu FILE...` (copy with the date in the name), `ednt FILE` (edit keeping the modification time).
|
||||
- Archives: `extract ARCHIVE...` unpacks tar of any compression, `.xbps`, zip, rar, 7z, gz, bz2, xz, zst, lz4 and Z; `compress NAME.tar.gz|tar.xz|tar.zst|zip|7z FILE...` packs by the name's extension. A missing tool is named together with the package to install.
|
||||
- Disks and memory: `df`, `dft` (with types and a total), `dftl`, `mnt` (mounted devices), `mounts`, `devid` (lsblk, blkid and lsusb), `snaps` (root snapshots), `free`, `meminfo`, `cpuinfo`, `gpumeminfo`.
|
||||
- Processes and history: `psa TEXT`, `pst TEXT` (as a tree), `psg`, `psmem`/`psmem10`, `pscpu`/`pscpu10`, `j`, `hgrep TEXT`, `histat [N]` and `histop10` (most used commands), `EC` (the previous exit code), `please` (the previous command again with sudo).
|
||||
- Packages: `upd` and `updy` (`das-update --cli` with snapshots, `updy` without questions), `pkgshow [TEXT]` (installed), `pkgfind TEXT` (in the repositories), `pkgowner FILE|COMMAND`, `pkgclean` (package cache and orphans).
|
||||
- Network: `myip`, `netinfo` (addresses, gateway, DNS, public IP), `oports` and `gport TEXT` (listening ports), `ping5`, `fastping`, `header URL` and `headerc URL` (HTTP headers, with compression), `listen PORT`, `serve [PORT]` (the current directory over HTTP), `rmhost HOST|LINE` (clean `known_hosts`), `nftlist`, `firewall` (`dfw status`), `weather [CITY]`, `cheat COMMAND` (cheat.sh).
|
||||
- Docker: `dps`, `dlog CONTAINER`, `dcu`, `dcd`, `dcl`, `dcp` (compose up, down, logs, pull), `lzd`, `lzg`.
|
||||
- Small tools: `calc EXPR`, `epoch [SECONDS]`, `genpass [LENGTH]`, `now`, `nowdate`, `note [-c] [TEXT]` (`~/.notes`), `todo [-l|-r N|-c] [TEXT]` (`~/.todo`), `csrc FILE.c` (compile and run C), `man` with coloured headings.
