7 deprecated Linux commands you need to stop using - and what to use instead

The article explains that several legacy Linux commands are deprecated due to security concerns, lack of maintenance, and the availability of better-integrated, feature-rich alternatives, and recommends modern replacements. Examples include replacing `ifconfig`, `route`, `netstat`, and `arp` (from net-tools) with `ip`, `ip route`, `ss`, and `ip neighbor`; `iwconfig` with `iw`; `scp` with SFTP or `rsync`; and `egrep`/`fgrep` with `grep` (now supporting extended regex and fixed strings). It advises avoiding legacy tools where possible and adopting the newer commands for improved security, efficiency, and kernel integration.
