Linux tip: you can edit files from within less by pressing "v". This will launch your default editor.

If you do not have a default editor specified, you can specify one by adding the following lines to your .bashrc:

# set default editor
EDITOR=/usr/bin/vim

Substitute vim for whatever editor you prefer. (Which is obviously vim :)

(Possibly relevant to @b0rk 's interests)

So I hit a flag in diff, --unchanged-group-format. It does not show up in the manpage. It does not show up in --help. You can search both those channels for that string and you will not find it.

You know where it shows up first? If you Google it, you'll get an example in https://www.gnu.org/software/diffutils/manual/html_node/Line-Group-Formats.html.

So why doesn't it show up in the manpage? Well, it does! If you read the entire manpage. With your eyes.

  -D, --ifdef=NAME                output merged file with '#ifdef NAME' diffs

"What do you mean it isn't documented? Of course it's documented. You did read every line and do some template-substitution in your brain, didn't you?"

This isn't advocating for not reading the manpage. If you really want to understand how the tool works, you read the whole manpage. And probably the source code.

... but I don't want to understand how the tool works. I want to diff two files and not have the lines that are the same get emitted.

And I think a lot of application- and solution-generating computer people, most of the time, in most of their careers, are operating on that level of depth. Problems come in too fast and with too much variety. You absolutely go deep on some things. There is no time to go deep on everything.

So how do we address this (other than throw up our hands and say "Relying on Google's fuzzy search of the whole Internet and vibe-coding LLMs is the future actually")? I don't have magic bullets, but a "fuzzy search" mode in something like less that could take an input like --unchanged-group-format and twig that it if there's no exact match, it might be related to --GTYPE-group-format would be nice.

Maybe I should mock that up in emacs. Actually, I bet someone already put it in emacs. ;)

The less I need, the better I feel.

Setting the pager to vim in #jujutsu will cause terminal escaped sequences to be printed(unreadable). So for now I use less with custom keymaps.

Compiling the latest release of less so I can get that sweet, sweet wordwrap feature.

Umm... can someone who has the spoons handy log an issue that their latest release (non-beta) tarball is double-gzipped? (https://github.com/gwsw/less/issues)

#SpoonTheory -- I'm doing fine, but dealing with github REALLY DOES cost a couple extra spoons even when you're having a good day, lol. Stop using that MSFTy GPL-violating crap, my peeps! :P~

Any people on here who have both experience with #ddd + #teamtopologies and #less or #fast?

It feels that stream-aligned teams and the fluid teams is a big conflict? And I'm wondering what kind of tradeoffs you've found when working with one or the other?

For example, how do devs build deep domain expertise in fluid teams?

Or if you do TeamToplogies, does it always mean that you might need to rework your architecture so teams can work on value and not just on individual components?

Elon Musk’s charity may bear his name, but it can’t seem to match his penchant for high-dollar spending.

According to a New York Times analysis of his charity’s giving in 2022, the #Musk #Foundation gave out just $160 million in grants
—a whopping $234 million #less #than the five-percent #legal #minimum it needed to distribute between 2021 and 2022.

It was the fourth-largest shortfall of any U.S. charity in 2022, the last year for which records are available.

The revelation was one of multiple in the Times’ report on Musk’s charitable giving, which has often benefited his own associates or those of his companies.

Musk reportedly filled some of the foundation’s coffers by donating Tesla stock, which he is allowed to claim as a tax deduction.

Not all of the charity’s donations have benefited his own interests, however:
The foundation donated more than $1 million to schools in Flint, Michigan, and a charity aimed at helping children there.

But where that foundation donates is still up to him and the foundation’s board—which includes just him and two other volunteers.

#Less Command Examples in #Linux

Pro tip: `less` can filter the lines it displays. Hit the “&” key and enter a search pattern. You’ll only see lines matching the pattern.

Want to only see lines that _don’t_ match the pattern? Prefix the pattern with an exclamation mark.

Super useful when looking at logs, for example.

The #less man page is definitely worth a read, it can do a bunch more stuff you might find interesting.

Ça fait des années que j’utilise less en pipe avec grep sur des logs. Je découvre que oui je peux avoir des logs colorés avec less si c’est prévu dans les logs !

CVE-2023–26604: #systemd before 247 does not adequately block local privilege escalation for some #Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because #less executes as root when the terminal size is too small to show the complete systemctl output.

Linux: Farbige Terminalausgabe in less

Damit die Terminalausgabe lesbar ist, verwende ich die Option "--color", aber es bleibt alles schwarz-weiß. Was muss ich machen, damit "less" funktioniert?

Wow, after 25 years of Unix experience, I learned that you can filter output in #less.

Press ampersand (&) and enter a regex to show only lines matching the regex.

Press ampersand (&) and then exclamation mark (!) to apply an inverse filter.
