Getting Help in Terascan
To get help with the Terascan XVU commands, select the online help in
the window in question, or type man xvu in a Terascan window. To get
help on a specific Terascan Command Line command, type man commandname.
A complete list of Terascan Command line commands can be found by typing
man terascan in a Terascan window. Some of the most used (and useful)
commands are listed below:
