Practica tu reguexperimentación con Quodrle[1] y grep|egrep 😅
Mi último regexp del ejercicio:
```
$ grep '^b....$' /usr/share/dict/words | grep r | grep '^b..[^r].$' | egrep -v 'h|e|l|o|a|s|u|g|u|l|y|f|z|t'

W jednym z pokoi matriksowych, które lurkuję padło pytanie, jak policzyć w LibreOffice słowa, ale z pominięciem jednoliterowych.
Temat wydał mi się ciekawy, więc trochę poszukałem i skleiłem znalezione dwa myki: sposób na konwersję .odt do .txt z egrepowaniem słów o odpowiedniej minimalnej długości. Może się komuś przyda:
libreoffice --headless --convert-to txt:Text test.odt &> /dev/null && < test.txt egrep -wo '[[:alnum:]]{2,}' test.txt | wc -w && rm test.txt

Does anybody have experience with zipgrep? I'm trying to run a regex with alternation but for some reason it's not working. I run:
zipgrep -E "(wordA|wordB)" file.zip
on a zip file which I know it contains bot words within its files, but it returns nothing, if I uncompress the file and run egrep, it works fine 🤯
Edit: fixed the command again bc apparently I can't type

This is a perennial stupidity in the C and C++ worlds.
Because the C and C++ standards leave some things up to _other_ standards, including (ironically) #POSIX, the idea that one shouldn't talk about them in the comp.std.c and comp.std.c++ newsgroups mutated into a stupid dogma that C and C++ programs shouldn't rely upon anything from these other standards.

That's the thing. The GNU egrep and fgrep _already are_ shell scripts. Paul Eggert added this change _to those shell scripts_.

You're a bit late. Debian had a bug about this, and patched the warnings out, back in 2022.

The Debian bug log also points to the two GNU project bug reports, where Paul Eggert et al. argued against undoing the new behaviour.
