File this under #shell #functions I should have written years ago:
function grepc {
#Do a grep -c, but skipping files with no results
grep -c "$@" |grep -v ':0$'
}
Amin, minor deity of the legume realmOh, didn't know about -c. I usually just pipe to wc -l I guess.
-c, -l, -h, -H, and -q are my favorite #grep flags. :D
Huh, that almost became a [Marcel Duchamp] reference. π
I just use -v and -E

thedoctor...and bash instead of zsh
...and grep/awk/sed instead of jq
...and firefox instead of chrome
...and the fediverse instead of facebook
Face it... I'm an unpopular-opinion neckbeard level boss. XD

@rl_dane Those are so not comparable!
@thedoctor @rl_dane @amin @mirabilos At least bash and zsh is comparable to grep ripgrep, as zsh is just a strictly better bash ;)

kabel42@kabel42 @mirabilos @rl_dane @amin @thedoctor No, it's absolutely not fun, first of all it breaks all scripts. They break all the shortcuts that I use all the time in interactive sessions, it's slow, and if you want to configure it, guess how you configure a command line tool it boots up a web server where you configure it... the whole thing is utterly ridiculous.
@mirabilos @rl_dane @amin @thedoctor @sotolf you probably have some browser installed anyway so why not use it. And you can rewrite all your scripts in a new, more sane, language that is not based on some legacy tech. 
@mirabilos @rl_dane @amin @thedoctor @sotolf extra fun if you install it on a shared server in the lab and make it the default shell.
@kabel42 @mirabilos @rl_dane @amin @thedoctor On most of the servers that I manage, no I don't have a browser installed, why would I? And fish's language, sane? what you smoking bro? I want some of that as well.
@rl_dane @kabel42 @sotolf @thedoctor @amin I do have lynx, but also the feeling that that isnβt what you are thinking of when you write browser
@rl_dane @sotolf @thedoctor @amin @mirabilos fish, the shell for people that prefer mouse over keyboard 
@kabel42 @sotolf @rl_dane @amin @thedoctor also, I hate how "legacy" and "modern" are fighting words nowadays. Best to avoid them in polite conversation.
@mirabilos @kabel42 @rl_dane @amin @thedoctor
Legacy is mostly the safe route to go anyway, tried and tested, I am the one that gets called if shit stops working, and I'd rather have something I know and makes sense, with tons of resources of administrators of the before times having struggled with them to help me figure out what is going on. Rather than modern stuff, with their ai documentation, discord "forums" and shipping their whole pc (docker) because they couldn't get their shit to work on a clean system :p
@mirabilos @rl_dane @amin @thedoctor @sotolf legacy had old bugs that are well documented and no one dares to fix, modern has, too often, not learned from past mistakes
@kabel42 @mirabilos @rl_dane @amin @thedoctor
Hey I relied on that bug!
@sotolf @kabel42 @mirabilos @rl_dane @thedoctor
Oh haha so it was intentional. I was wondering.
@amin @kabel42 @mirabilos @rl_dane @thedoctor With a bunch of nerds like us, of course we were playing off that one yeah :p
@kabel42 @mirabilos @rl_dane @thedoctor @sotolf
Haha, you got it too! XD

ksh got started in... 1983? That's not legacy? XD

@kabel42 @sotolf @rl_dane @thedoctor @amin not in the sense if the word that is commonly used/understood contemporarily, no
@mirabilos @sotolf @rl_dane @thedoctor @amin If you are refering to the original version, the Wikipedia definition doesn't feel that off: "In computing, a legacy system is an old method, technology, computer system, or application program, "of, relating to, or being a previous or outdated computer system",[1] yet still in use." -- https://en.wikipedia.org/wiki/Legacy_system
@kabel42 @sotolf @rl_dane @thedoctor @amin thatβs not how the word is used these days. βlegacyβ and βmodernβ are fighting words, at this time. πΎ
@mirabilos @sotolf @rl_dane @thedoctor @amin matches my understanding and use of the word π€·
Alternatively, something that used to be popular but has been replaced with something newer in many applications but remain in some use cases

Probably because people are addicted to the breakneck pace of "progress," novelty, and chasing their tails.
Maybe I'll spin up a laptop that only runs Unix v4 in a VM to try to spin the earth a tiny bit in the other direction. π

ksh is a type-safe, memory-safe language supporting modern paradigms like concurrency, higher-order functions and pattern matching. Its standard library even supports distributed applications and serverless architectures as well as microservices.
Not sure what should be legacy about that?
@mirabilos @nik @thedoctor @kabel42 @sotolf @amin
WAT. Sounds amazing, got an example?
Is this mksh or ksh93/2020?
@rl_dane @nik @thedoctor @kabel42 @sotolf @amin ksh2020 is completely gone. Thereβs now βksh93u+mβ by MartΔ³n @mcdutchie as actively-developed version. ([Overview]β¦ which I should update some dayβ¦ oopsβ¦)
This is, for now, an mksh thing; it stems from [a thread] by @navi in which she desires something like that for sh, but I chose to add it to the Korn shell-style function syntax instead because it is easy to add there without breaking anything and because it leaves the POSIX space open for future standardisation.
Itβs deliberately not yet documented in the manpage or so because it can change at will and without prior notice and is, at this point, only something for people to play around with, to get a feeling for it, before it can become standardised.
(Also, I very much dislike the idea of adding it to the () of POSIX-style functions, as that would look too much like a subshell.)
general idea is:
| function (a b=foo) name { β¦ }
β¦ is identical enough toβ¦
| function name {
| a=$1; shift
| if (( $# )); then
| b=$1; shift
| else
| b=foo
| fi
| β¦
| }
Note that default arguments can have side effects (like a parname=[] mutable default argument in Python)β¦
function (count=$((++selfcount_cnt))) selfcount {
echo calling me for the ${count}th time
}
β¦ but they are shortcut-evaluated (i.e. selfcount_cnt will not be incremented if selfcount is called with an argument), like in most logic (if (foo != NULL && foo->bar > 1) would crash if it werenβt).
The [commit message] has some more information, and of course you can read the diffs linked (user=pass public as usualβ¦ fscking LLM scrapersβ¦) for more info, check.t contains some self-tests for this.

(Also, I very much dislike the idea of adding it to the () of POSIX-style functions, as that would look too much like a subshell.)
the main point of the thing was making the posix () not useless though ~w~
subshells arenβt allowed after a word like that in any context i can think of so imo someone would need to really go out of their way to make the syntax look confusing (most often subshells only pop up at the start of a command, or after a pipe, neither of which match function declarations much)
foo(nya mew=beep) {
echo $nya $mew
}
selfcount(count=$((++selfcount_cnt))) {
echo calling me for the ${count}th time
}
iβm not a fan of the side effect thing much, but itβs something i think we should have anyway due to specifying the default value the same as any normal assignment, something like mew=${2-beep}, so count=${1-$((++selfcount_cnt))}
@sotolf @thedoctor @kabel42 @mcdutchie @navi @amin @rl_dane @nik yes, thatβs sort of how it works, except it actually inspects argc I think.
Hmmmm, use of $n (where n is number) in default args could be⦠"interesting". But, I think, possible.
@navi @sotolf @amin @rl_dane @kabel42 @mcdutchie @nik @thedoctor yes, it inspects argc, and it shifts after each, so $1 is always the one in question, though I donβt think you can do anythingn useful with it.
There also is no provision for namerefs yet (and thatβs beyond POSIX and very shell-specific anyway). Might be interesting, perhaps with a prefix before the variable name.

What the absolute forking fork egad Noooooooo!!!!!!!
@amin @sotolf @thedoctor @kabel42 @rl_dane but systemd does the same if it crashes, it even displays a QR code so you can easily connect with its built-in webserver to access the error information! This is the future!!!!11
@kabel42 @sotolf @amin @thedoctor @rl_dane systemd is an attempt at USERLAND.EXE and Poettering, Bocassi et al. do work for MS after allβ¦

1. When in doubt, copy Windows.
2. Moar systemd
3. ?!?!?
4. PROFIT!!!
@rl_dane @mirabilos @amin @sotolf @thedoctor maybe it's just the same code?
