Big stuff

-euo pipefail now being a posix standard is really awesome, as well as readlink and realpath (didn’t even know these last two were non-standard).

Informative and interesting article, thanks for sharing.

Quite a few of these POSIX improvements were new to me, even though it turns out that they already exist in the GNU versions of the tools.

Title is misleading. Article starts with a gigantic useless text about “In the 1950s”.
