Here are the top 10 advanced Linux commands for mid-level users, in my personal opinion, each one of us should know these commands and be comfortable with using them.

1) ifconfig — used to configure/display the kernel-resident network interfaces

ifconfig -a

2) netstat — displays various network related information such as network connections, routing tables, interface statistics and ports used

netstat -anpt

3) nslookup — A network utility program used to obtain information about Internet servers. As its name suggests, the utility finds name server information for domains by querying DNS.

nslookup -query=mx abc.com

4) dig — is a tool for querying DNS nameservers for information about host addresses, mail exchanges, nameservers, and related information.

5) top/htop — Displays the processes of CPU, Mem and Load Avg

6) vi/vim (visual), emacs, nano — most commonly used editors in Linux.
