FreeBSD manual pages online: I figured out what's wrong with two of the examples in the first of these three screenshots.
The wrongness is easier to see when the text from the page is copied to nano (shot 2) and Fresh (shot 3). What appears to be an ordinary space is in fact:
― non-printable U+0009 (CHARACTER TABULATION) (horizontal tabulation (HT))
A tab.
So, examples are broken when copying from official documentation.
This might be <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274208>:
274208 – man.freebsd.org with GNU groff 1.23.0: issues with text alignment (e.g. justification) and adjustment
– the src tree is not bugged at <https://github.com/freebsd/freebsd-src/blob/7e06c33151e7664f6d664ee282d8da1985ce94aa/contrib/vis/vis.1#L174-L183>.

lolcat tricks and fun
In case you have ever wondered what it would look like to have all of your favourite console output piped through lolcat(6) 🏳️🌈, here is a nice example
required (one of *sh is enough)
- Open Source OS
- sh
- csh
- ksh
- zsh
- bash
- fish
- syntax skills on piping I/O
- love of colours
- typing skills
- sense of humour
typing
man lolcat...will get you the standard sh output delimited by the man command itself. This means that I used a simple trick to get all of my output piped through lolcat
ssh -Xv -p65534 -l userid |lolcatThis command syntax gets all of my commands in that ssh session piped through lolcat, creating an awsome rainbow colour galore
notes
- ssh secure session piped through lolcat gets you a slower output, compliments of the inner workings of lolcat. Feel free to optimize the program and release the patches if the lowerspeed irks you.
- test the speed by doing
ls -lR ~and compare that in a standard ssh sessios without full lolcat pipe- I used the -X switch because I also start X programs from this shell (which I run in Xorg {it also works in wayland})
- I use the -v switch because I love log messages of ssh
- you can also animate your piped lolcat output with
lolcat -a- I watch the output on a large TV also, because lolcat(6) 🏳️🌈 is that awsome
sources:
lolcat --helpman lolcat(6) 🏳️🌈

man man(1)

🤣 Oh, joy! Yet another groundbreaking revelation: people like *examples* in man pages. Who could have guessed? 🚀 Thank goodness someone finally added the most *basic* #examples to #tcpdump and #dig... because, you know, reading is hard. 📚🔍

@zer0unplanned This post looks very useful. I made a similar tool (still in beta with errors) to grab screenshots and raw data of manual pages #manpages for #linux commands, in this case #ssh info, and to present the different layers that are the OS, app and nixos settings. The program ssh-key-manager is in my flake https://repoducible.org ( features/security/packages #flake #part can be pulled out into another flake) & bit of a monster. Yours looks ultra compact #nixos

Nr 4. der #Artikelserie:
#SteadyCommunityContentNach dem Einbau des #Raspberry Pi 4 in das mysteriöse #Gehäuse kommt jetzt die #Inbetriebnahme. 😁
Mit #Linux arbeite ich zwar selten, doch grundsätzlich komme ich damit klar. Wo früher noch mühsam gegoogelt oder #Manpages konsultiert wurden, frage ich heute #ChatGPT. Das geht für eine Root-Cause-Analyse bestimmt 100-mal schneller. Also, womit fange ich an? 🤔
