Cuatro herramientas básicas para filtrar y procesar texto en #líneadecomandos: #sed, #grep, #cat y #awk

Entre los comandos básicos de todos los sistemas Unix podemos encontrar un puñado de ellos destinados a trabajar con flujos de texto (procesándolo, seleccionándolo, editándolo, etc).

Gracias al hecho de poder encontrarlos en todos los Linux, BSD (y con ello, macOS) y Windows 10-11 (gracias a WSL) del planeta, tener una noción básica sobre la labor que realizar puede resultar muy útil si en algún momento necesitamos recurrir a ellos; por ejemplo, para crear shell scripts.

A continuación, te presentamos un somero resumen de cuatro de estos comandos, sin ánimo de exhaustividad a la hora de examinar sus diferentes opciones.

For todays #FollowFriday I'm going to do something a bit different. We have a lot of new users, one of the biggest surges we have seen in a while. As such a lot of new users are looking for high quality, long-standing, accounts to follow. Similarly many of the new users need some help getting attention and making new friends.

As such I am going to do this #FF in a few parts. One for old users I have mentioned in previous posts, as well as some of the new users who have been making quality posts and been active for at least a week now. Hopefully this will be more helpful.

Also a section for some bots might be useful.

I will use a persons profile description here as I dont want to misrepresent anyone.
