Wusstet ihr, dass `grep -r "TODO" .` euch zeigt, wie viele Baustellen ihr in eurem Projekt habt? 🔍

Bei mir: 47 TODOs, 3 FIXMEs und ein Kommentar der einfach nur "warum???" heißt. Das Projekt läuft seit 2019 in Produktion. 😅

Manchmal ist freie Software auch einfach ehrliche Software.

Guten Morgen! ☕

Wusstet ihr, dass `grep` seinen Namen von einem `ed`-Befehl hat? `g/re/p` = global / regular expression / print.

50 Jahre alter Unix-Befehl, läuft heute noch auf jedem Linux-System – und ist schneller als die meisten "modernen" Tools. 🦕⚡

Alte Software, die einfach funktioniert: das ist auch freie Software-Kultur.

#Linux #Unix #grep #FreieSoftware #Terminal

Folgendes funktioniert also tatsächlich: man erstellt sich im modernen im #UEFI Modus installierten Betriebssystem (zB LMDE7) ein Desktop Icon, das den Befehl sudo efibootmgr -n 001A und dann einen reboot ausführt. Dann fährt der Rechner wieder runter und startet Windows 7 im #MBR Modus. #efibootmgr listet auch die Hardware #GUID des SATA #controller Dies kann man sich mit #grep im Befehl greifen. Damit wird das resistent gegen Änderungen in der Nummerierung.

Guten Morgen! ☕

Wusstet ihr, dass `grep` seinen Namen von einem ed-Befehl hat? `g/re/p` = "global regular expression print". Seit 1973 rettet es täglich unzählige Admins vor dem Wahnsinn.

Wusstet ihr, dass `grep` seinen Namen vom ed-Befehl `g/re/p` hat? "Global Regular Expression Print" – also: such überall, zeig mir's. 😄

50 Jahre später tippt man immer noch `grep -r "TODO" .` und bereut sein Leben.

Wusstet ihr, dass `grep -r "TODO" ~/projekte/` um 2 Uhr nachts eine existenzielle Erfahrung sein kann? 🌙

237 offene TODOs. Manche von 2019. Eines lautet nur: "irgendwann richtig machen".

Das Schöne an freier Software: Der Code liegt offen da – mitsamt all seiner ehrlichen Verzweiflung. 😅

Пока другие выбирают архитектуру, поиск по коду в GitVerse уже работает

Поиск по коду — одна из тех функций, ценность которых ощущается мгновенно. Она либо есть и экономит часы, либо её нет — и ты начинаешь открывать файлы вручную, клонировать репозиторий, запускать find или средства своей IDE и вспоминать «где же это было». Мы добавили в GitVerse поиск по коду в репозиториях. и сделали это быстро. Не потому что «срезали углы», а потому что опирались на инструмент, который десятилетиями решает задачу поиска по коду внутри Git: git grep . Пока другие поднимают тяжёлые поисковые платформы, возводят кластеры, строят индексаторы, мы выбрали простое и проверенное решение, которое работает прямо сейчас.

Maybe unpopular take, but cat foo | grep is better than grep, because it has a cat in it. Cats are cute!

Wusstet ihr, dass `grep` seinen Namen von einem `ed`-Befehl hat? `g/re/p` = "global / regular expression / print". Also buchstäblich ein Akronym aus nem Texteditor-Kommando aus den 70ern. 🐧

@gumnos

A subtler version of another part of the bug is caused by a similarly bad handling of EOF in another part of #FreeBSD #grep's roll-its-own I/O library.

https://cgit.freebsd.org/src/tree/usr.bin/grep/file.c#n139

With your example of

/usr/bin/grep x

You can enter a single space, then terminate the read(2) with the EOF special character; and you'll have to send EOF 2 more times to get grep to exit.

A regular file containing just a SPC exhibits the same behaviour of wrongly needing to receive EOF from read() twice.

@gumnos

Here's part of the bug.

https://github.com/freebsd/freebsd-src/blob/main/usr.bin/grep/file.c#L210

There's no handling of EOF if it occurs as the very first read() of the file.

A zero-length regular file and /dev/null will also result in two read()s returning 0 before grep then exits.

This code was introduced in commit 3ed1008b891eb34df96a6ae4f87e5a3270be759c in 2010.

#OpenBSD's version of this code is older and uses the normal C stdio library routines and getline(3) rather than rolling its own layer over read().

#FreeBSD #grep

#TerminalTip: how to use #grep to highlight a line of interest to you without removing any other lines:

Let's say you're using a command that lists something, and you want to highlight any line that contains the word "apple", without highlighting anything else, or removing any lines from the output. Here's how you can do that:

some_command |grep --color -ie ^ -e "^.*apple.*$"

@gumnos

I am the voice of experience:

@rl_dane was talking about getopt yesterday, and I found that I was running a /usr/local/bin/getopt from ports with very different handling of '--' (alluded to by @steeph , so I had been checking it out) to the actual #FreeBSD /usr/bin/getopt on the machine.

I wouldn't be surprised if I'm running a different /usr/bin/grep (I checked that.) to you. "I'm using FreeBSD grep." has famously been two entirely different programs over the years.

#getopt #grep

@gumnos

But did you also do a

type grep

to ensure that you were running /usr/bin/grep and not something from ports, nor some 'helpful' alias/function that someone has snuck in to /etc/profile and /etc/csh.cshrc?

It wouldn't be the first time in history for the latter. Best to eliminate it straightaway so that the blame can be squarely hung upon /usr/bin/grep.

#grep #FreeBSD

@gumnos

Not reproducible, as expected, on my older #FreeBSD here.

Make sure to double check for embarrassing shell scripts, aliases, directories in $PATH, and shell functions before writing that bug report. I've seen that so many times over the years. (-:

#grep

@amin

-c, -l, -h, -H, and -q are my favorite #grep flags. :D

Huh, that almost became a [Marcel Duchamp] reference. 😅

GUIs are very nice yes, but nothing makes you feel quite as powerful as a successfully chained command line pipeline.

For example, taking a massive log file and filtering it through cat | grep | awk | sort | uniq -c to find the exact problem in seconds is a form of wizardry that modern UI simply cannot replicate.

Sometimes I believe the pipe | might be the single greatest invention in computing history lol 😋

💾 The File Count Challenge 🔎

Have you ever wondered how many PDFs, images, videos, or particular kind of files you have on your device? It is the time to find out.

I am hereby proud to officially launch a Fedi-wide file count challenge, in exclusive partnership with the 2025-27 class of @xpub 👾

💁 How to participate

1. Go to your main device (not mobile)
2. Open the terminal
3. Run find . | grep '.pdf$' -c (on Windows: gci -r | where Name -match '\.pdf$')
4. Repeat the previous command, replacing “pdf” with any file format you are interested in sharing. We suggest: jpg, mp3, and png. 🔆 Bonus: html, js, ttf, odt, svg
5. Take a screenshot of the output
6. Share the screenshot on the Fediverse, using the #fileCountChallenge hashtag (please, copy-paste the actual text from the terminal in the image description/alt text)
7. Add your (user)name and results to the scoreboard
8. 🆒 Bonus: share the story explaining why you have so many/little files for one format.

🏆 Awards

There is a secret prize for the three people who have the most PDFs, JPEGs, and HTMLs. More info to follow.

Boost, share, fork… Do whatever you want, but please have fun while doing it.

I willl keep writing updates. Yaaaaaaay ⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️⌨️

Утилита r.exe

В программировании часто приходится писать программные компоненты, которые, в общем очень похожи друг на друга по своей структуре и API. В заметке я представил простую утилиту r.exe для авто-замены токенов в файлах и названиях файлов.

Arrivée ici début 2025, big up aux @admin de Piaille.fr ! #introduction :
Tombée dans la marmite #OpenSource en 2000, je me nourris de commandes #bash. Fichiers texte, #grep et ses jolies #regex, #ansible, #git, #greasemonkey, les tests auto et la supervision sont tes amis.
Cordes frottées, grattées et frappées, sons soufflés, chantés ou beatboxés, sons électro ou scratchés me touchent. Rien de tel qu'une bonne soirée à jammer / à enregistrer pour un beatmaker / à débarquer sur scène pour accompagner quand il manque un instrumentiste / à repiquer des morceaux entiers sur papier à l'ancienne / à improviser avec les enfants
Engagée #AMAP et pro #CNV

I've mirrored a relatively simple website (redsails.org; it's mostly text, some images) for posterity via #wget. However, I also wanted to grab snapshots of any outlinks (of which there are many, as citations/references). By default, I couldn't figure out a configuration where wget would do that out of the box, without endlessly, recursively spidering the whole internet. I ended up making a kind-of poor man's #ArchiveBox instead:

for i in $(cat others.txt) ; do dirname=$(echo "$i" | sha256sum | cut -d' ' -f 1) ; mkdir -p $dirname ; wget --span-hosts --page-requisites --convert-links --backup-converted --adjust-extension --tries=5 --warc-file="$dirname/$dirname" --execute robots=off --wait 1 --waitretry 5 --timeout 60 -o "$dirname/wget-$dirname.log" --directory-prefix="$dirname/" $i ; done

Basically, there's a list of bookmarks^W URLs in others.txt that I grabbed from the initial mirror of the website with some #grep foo. I want to do as good of a mirror/snapshot of each specific URL as I can, without spidering/mirroring endlessly all over. So, I hash the URL, and kick off a specific wget job for it that will span hosts, but only for the purposes of making the specific URL as usable locally/offline as possible. I know from experience that this isn't perfect. But... it'll be good enough for my purposes. I'm also stashing a WARC file. Probably a bit overkill, but I figure it might be nice to have.
