Thinking about recursive git clones. also how some command line tools are pretty much like functions, and how therefore a programming environment could be built up function by function rather than pulling in a huge package like python. But batteries included makes for a lot of ease |

After struggling a bit with trying to display from a line of a file to the end (in this case "Description:" to match <code>apt show</code>) I was reminded of a terminal feature I heard of, where it would automatically page outputs such that you'd see the first lines of output from a command, or the whole output if it fit on a screen. I think that was a plan 9 feature. Ended up going with a 2-part command - use grep to find the start line, then use tail to start from that line, to the end |

List installed debian packages by size
dpkg-query -Wf '${Installed-Size}\t${Package}\n' | sort -n
But what are the units here? kilobytes? probably. But would be nice to have units. Powershell style structured output could be useful here.
Nice browser of installed packages: dpkg --list
Journalctl shows all messages you can see by default: journalctl
Tail messages with journalctl with -f for follow:
journalctl -f
