Still using these obsolete Linux commands? Perhaps it is time to look for alternatives.

Still using these obsolete Linux commands? They might be popular from the olden days but perhaps it is time to look for alternatives.

    Listed programs:

    • scp - “potentially deprecated”
    • e/fgrep - replaced with grep flags
    • net-tools, which includes
      • netstat
      • arp
      • route
      • iptunnel *nameif
    • ifconfig
    • iwconfig
    • iptables

      Replacement:

      • scp → rsync or sftp

      • egrep --> grep -E

      • fgrep --> grep -F

      • netstat --> ss

        • arp --> ip n
        • route --> ip route
        • iptunnel --> ip tunnel
        • nameif --> ip link

      • ifconfig --> ip

      • iwconfig --> iw

      • iptables --> nftables

      They can take ifconfig from my cold, dead hands. I will not learn ip

      scp too. What even is an rsync? BS that’s what!

      Just to be clear, most of these (think about egrep/fgrep for 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.

    The thing about these deprecated tools is that the replacements either suck, are too convoluted, don’t give you the same info, or are overly verbose/obtuse.

    ifconfig gave you the most relevant information for the network interfaces almost like a dashboard: IP, MAC address, link status, TX/RX packet counts and errors, etc. You can get that with ip but you’ve got to add a bunch of arguments, make multiple calls with different arguments, and it’s still not quite what ifconfig was.

    Similarly, iwconfig gave you that same “dashboard” like information for your wireless adapters. I use iw to configure but iwconfig was my go-to for viewing useful information about it. Don’t get me started on how much I hate iw’s syntax and verbosity.

    They can pry scp out of my cold dead hands.

    At least nftables is syntax-compatible.

    Why did they even get rid of the net-tools stuff? Since everyone is still using them why not just bring them back? I don’t see how they can be a security issue. When I set up a new distro one of the first things I do is install it again.

    Even the article says that the reason scp is so popular is that it copies the cp syntax. Why constantly force people to relearn jobs they already know how to do?

    Rustscan is supposed to be so much faster than nmap but I still use nmap because I can’t be bothered learning another tool. Just use the same syntax for gods sake.

      sometimes syntax changes are part of the decision to do a rewrite. these are user interfaces at the end of the day. i’m not saying you’re wrong about any particular case, but it’s like saying “why make Instagram when Facebook exists” or “why make Scala when Java exists” etc. i like a good fresh look at how we use and instrument and teach our development tooling.

      also, when i was 18 and would tell IT professionals i was getting a computer science degree, the #1 response was, “get ready to spend the rest of your life learning new things.” and i’ve found that to largely be true

    Not only will I continue to use these commands, when/if they are ever officially removed, I will reimplement them myself because I am that intent on continuing to use them for the rest of my life. In almost all cases, the reasons we still use those commands is because they truly are the best tool for the job, at least from a UI/UX usability point of view.

    And, you can accuse me of being stuck in familiarity and traditional thinking and you’re probably right, but I think the alternatives mentioned are simply garbage UI/UX. Their implementations may be beautiful and perfect under the hood, I don’t care. I will be happy to fully take advantage of that functionality and implementation when I write a wrapper around them to implement the deprecated command line interface instead.

    Also, the article is straight up wrong in some places:

    If you read an old Linux book from before 2010, you’ll find the arp, route and other such networking commands that do not exist in your Linux system anymore. You cannot even install them.

    That is simply not true. They are perfectly installable and work perfectly well. I’m running Debian 13 and it still includes a package for net-tools.

    You will have to pry things like route, scp and ifconfig out of my cold, hands on my cold, dead keyboard. Not going to happen. Period.

      Certainly whoever wrote that didn’t do a lot of distro-hopping. As far as I can tell, Gentoo still includes sys-apps/net-tools in the @system set, meaning that it’s not only installed by default, but it’s quite difficult to remove.

      End of story. That settles it. Case closed. No exceptions. That’s final. Consider it settled. It’s non-negotiable. End of discussion. That’s the final word. Nothing more to add. Enough said.
