Understanding the CLI

Usually a lot of HPC environment usage takes place via the Linux command line. For unfamiliar users here is a brief description of a typical CLI prompt.

[flight@chead1 folder]$ echo Hello World!
Hello World!

• flight is the name of the user.
• chead1 is the node the user is currently on.
• folder is the directory the user is currently in. If this is a ~ then that means you are in your home directory.
• $ indicates whether the user is a root user or normal user (root users see a #).
• echo Hello World! is a command that prints out "Hello World!". This is where commands you type will go.

The prompt can vary based on user preference and global environment configuration. The above is an example for illustrative purposes
