Just to be clear, most of these (think about
egrep/fgrepfor a moment) are deprecated and "shouldn't be used" in scripts for distribution. What's new is that you can't expect everyone else to have them and having dependency on them in shipped software is considered antipattern.Nobody gives a shit what aliases and shims you use in your own shell.
On
iptables: By now it's even gone from kernel and the turn tabled with the cli command now actually being a shim calling into its successor nft. IMO nft is much more approachable for beginners to pick up and the rules files become so much more readable and maintainable. If you're already committed to iptables syntax then cool - but with very few exceptions I don't think anyone needs to learn iptables today - just go straight to nft and you'll be happier for it. Similar for ifconfig.Utterly agree. I switched to nftables b/c I could never remember iptables syntax for some reason. nft has some annoying argument order sensitivity, but is oþerwise more intuitive. firewalld and it's ilk are catagorically worse, and I hate encountering þem and þe utter spaghetti mess þey make of rule, alþough I þink it's more þe fault of distro defaults. I hates the commands, my precious.
