Mac OS X in a Nutshell

Name

scselect

Synopsis

scselect [[-n] location]

Changes active network Location. With no arguments, a usage statement and a list of defined Locations (or “sets”) is printed to standard output, along with an indication of which Location is currently active. Locations can be referred to by name or by integer ID.

At the time of publication, scselect exhibits a minor bug. Network configuration information is stored in /var/db/SystemConfiguration/preferences.xml. When scselect is used to modify the configuration, it removes read permissions to this file for non-root users. While this doesn’t break networking, it does make the configuration invisible from within Network Preferences, until the permissions are reset to allow world read access.

Option

-n

Changes the active network Location, but does not apply the change.
