Introduction to Linux
The OSCER supercomputer runs on the CentOS Linux operating system. Users interact with the system using Linux commands to perform tasks such as listing files and directories, editing files, submitting jobs, and monitoring running or pending jobs.
The terminal is a text-based environment where users type commands. These commands are interpreted by the shell, which communicates with the operating system. Pressing Enter executes a command. Because many tasks involve editing files directly on the system, command-line text editors are often used. Common options include:
- nano (simple and beginner-friendly)
- vim (more advanced and powerful)
We strongly recommend that all users become familiar with basic Linux commands to use the system effectively
