Depends what you're doing. Hardware I/O changes often, plain old data processing hasn't. awk in particular didn't burden itself with 100,000 obsolete expansion modules like Perl and Python did, or changed as much as shell has; it remains a special-purpose language just for data processing, quite portable. Mostly. You can find it on anything from wireless routers on up, but occasionally we must tell people 'use nawk on solaris' or else they'll get a crusty old version backwards-compatible with 1977.

It took me a long time to do an FFT for Python 1.4.0 for the A1200, to the current, (04-10-2018), 3.7.0 for current machines, but I got there in the end. Everything is easy when code is written around current language versions but backwards compatibility is hard.
Python is one of the worst languages for backwards compatibility, its basic syntax changes with every sneeze.

Once done I will leave the Awk version for you... <wink>
If you're curious, there's a lot more to learn about awk. It's actually a very fast, powerful, and low-footprint language for processing text. (It had to be, to operate on 1977 hardware.) It's not a do-everything language, it has a few really nice features and not a lot else. You wouldn't write a menu system or graphical UI with it. But for data processing it's almost as powerful as perl.
