Working with the Command Line
About This Document
This document covers the use of the command line (shell) to interact with Athena. Before reading this, you should be familiar with the topics discussed in Getting Started with Athena.
The conventions used in Athena documents for describing special characters are:
- C-x or Ctrl-x means press x while holding down the Control key.
- joeuser@athena:~$ ls filename is a shell command. The text in bold is what you should type at the shell prompt ("joeuser@athena:~$"). The text in italics indicates that you should substitute the relevant information (in this example, a file name) before typing the command.
- Generally, you should press Enter or Return after typing a shell command unless instructed otherwise.
