Which command-line tool is often used for remote server management in Linux?

The command-line tool commonly used for remote server management in Linux is SSH, which stands for Secure Shell. SSH enables secure communication between a client and a server over untrusted networks by encrypting the data transmitted. It allows users to log into remote machines, execute commands, and manage servers securely. This protocol is essential for system administrators who need to maintain and configure servers from a remote location.

While PowerShell is indeed a powerful command-line tool for managing Windows systems and can be adapted for some remote management tasks in Windows environments, it is not primarily used in the Linux ecosystem. The Terminal refers to a command-line interface used in various operating systems, including Linux, but it does not inherently provide the remote management features that SSH does. RDP, or Remote Desktop Protocol, is specific to Windows systems for GUI-based remote access and not typically associated with Linux server management. Thus, SSH stands out as the predominant choice for remote server management within Linux environments.
