Today, I explored a variety of network-related commands in Linux. These tools are essential for managing and troubleshooting network issues in DevOps and cloud environments. Here’s a brief explanation and example for each:


Basic Network Commands

1. ping

Connects to a remote host using the Telnet protocol.


telnet command


8. hostname

Shows or sets the system's hostname.

hostname command


9. ip addr show

Manages network interfaces and routing tables.
