Legion commands

Legion's command-line tools support path-like naming of objects within context space. There are man pages for all of the commands listed here as well as resources on the Legion web site (<http://legion.virginia.edu>). Man page usage is man <command name>.¹ Please see your system administrator if you are unsure about using man pages on your system.

There are other sources of information about Legion context space and commands: the Legion web site has on-line tutorials and a quick guide to all commands (see <http://legion.virginia.edu/documentation.html>). You can also type

$ <command name> -help

to see most commands' full usage.

The following syntax is used to indicate optional and required parameters:

Please note that the sample outputs may not match your own. Your system administrator may have customized your system's context space or limited what parts you can see.

In the interests of space, most example LOIDs are shortened.
