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

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

iptables --> nftables

And if you really want the iptables UX, iptables-nft is also an option (at least on Debian). While I prefer firewalld most of the time on a server, my boss really wants to stick with the same tools he's used for 20yr; so iptables-nft it is.
