Unclear use of 'terminal' in How To Configure Security guide

Book: How To Configure Security
Revision: 0.8221103

In section 2.2.2.4 it is unclear what terminal is meant in:

Example using the touch command from the terminal to create an empty file
touch EAP_HOME/standalone/configuration/https-mgmt-users.properties

From me, it is clear it is Unix command, but it don't have to be clear for other readers...
