grep is a very important command. grep is considered complex by many for no well funded reason.

Why this bold statement?

There are not only man pages available, for all POSIX Operating Systems, but also very good tutorials, even in de Linux documentation project.

Don't think that you'll be able to learn high level grepping in just two, to five minutes. grep is a tool great at doing one thing in a great manner, pure Unix wise.

However

ls -R ~/your_dir | grep string

is already a simple level of grep usage

#grep #BSD #freeBSD #Linux #programming #OpenSource #technology #man

Mastodon is my main source of interesting new weblinks. I wondered if one can extract and save all that links to file.

So, I made a #shell script that can extract all weblinks from a Mastodon user's outbox, basically using #curl, #sed, #jq, and #grep.

https://codeberg.org/chrlns/linkfed/src/branch/main/linkfed.sh

Now, I can feed those links periodically into my #yacy instance and have a (private) search engine for my bookmarks.

I love the power of the #unix shell and #freesoftware.

Salut le mastomonde #linux francophone,
je suis à la recherche de supports de cours pour débutants en "#shell" genre, manip de bases de fichiers, #find #grep #cut #split le tout en format Moodle si possible ce serait génial.

Une idée d'où trouver ce genre de ressources ?

#TIL about #grep -w

Derp!

-w, --word-regexp
    The expression is searched for as a word (as if surrounded by
    ‘[[:<:]]’ and ‘[[:>:]]’; see re_format(7)).  This option has no
    effect if -x is also specified.

Today I Learned how to remove lines from a file which is sorted. In particular, I wanted to apply that knowledge to filter the list of already installed Homebrew casks (generated with `brew list --cask`) from the list of casks that I had installed in a a previous version (`20251201.previously_installed_casks.txt`). The list of casks pending installation then can be obtained by typing:

```bash
grep -Fxv -f <(brew list --cask) 20251201.previously_installed_casks.txt
```

(See https://explainshell.com/explain?cmd=grep+-Fxv+-f+%3C%28brew+list+--cask%29+20251201.previously_installed_casks.txt for a detailed explanation.)

That way, I can use the `--force` function to update my Homebrew cask database of installed items after manually upgrading Homebrew installation (from 4.5 to 5.0; for some reason it did not upgrade itself) but removing those items already installed:

```bash
brew install --force --cask $( grep -Fxv -f <(brew list --cask) 20251201.previously_installed_casks.txt )
```
Or this option, in case you want to go ahead with other items if any of the casks has problems:

```bash

for cask in $( grep -Fxv -f <(brew list --cask) 20251201.previously_installed_casks.txt)
do
echo; echo
echo "Installing: $cask"; echo
brew install --force --cask $cask
done
```

I wrote about my successful experience using a local #LLM to convert arbitrary #grep output into #Caddy config. I was surprised it worked so well with a model you can run on a phone!

The #grep command is essential to quickly locate information in text files.

It's Past Time To Stop Using egrep & fgrep Commands, Per GNU grep 3.8
"The egrep and fgrep commands have been deprecated since 2007"
...which means the post-install script for Vivaldi's RPM really ought to be updated! "egrep: warning: egrep is obsolescent; using grep -E"

I have to participate remotely again this year

While I'll miss visiting Seattle I'm still looking forward to some great talks and some hallway track

No charge to attend

The development of #awk was driven by the #Unix philosophy, functionally filling a niche between simpler tools such as #grep and #sed and general-purpose programming languages like #C . awk provided a powerful, high-level scripting language for data processing, filtering, and transformation.

Brian Kernighan: "…a lot of the software in the early days of Unix tended to be fairly simple and straightforward, and that reflected not only the relative wimpiness of the hardware but also the personal tastes of the people doing the work."

Ein fehlendes "aus" kann hier und da problematisch sein. In diesem Fall hat es seit mindestens 2016 niemanden wirklich interessiert. Denn wer bis zu diesem Untermenü bei den GREP-Stilen in InDesign vorgedrungen ist, erkennt, dass da ein "aus" fehlt und wählt trotzdem instinktiv das Richtige aus.

Trotzdem wäre es natürlich schön, wenn das mal gefixt wird. Mit deiner Stimme bei Uservoice kämen wir dem ein Stück näher. Danke im Voraus!
