NOTE: There are some changes to this document for Grid 2.5. Please see below and in-context. Please contact RCS with any questions.
The other method for logging in to the grid is through a terminal application. This command-line access over SSH (secure shell) requires that you are comfortable with Unix/Linux, but offers greater flexibility and power than a GUI: one can start batch or interactive sessions to use Grid software and resources, can automate file handling and work through scripts, and have more control over one’s environment.
