'/usr/sbin' is not included in the PATH environment variable.

[Sargon6]

Ho installato il modem USB SpeedTouch Manta su LMDE seguendo queste istruzioni:
http://www.linux-magazine.it/forum/index.php/topic,4260.0.html
Come potere vedere voi stessi,

Codice:

linuxmintlmde@lmde / $ pppd
Command 'pppd' is available in '/usr/sbin/pppd'
The command could not be located because '/usr/sbin' is not included in the PATH environment variable.
This is most likely caused by the lack of administrative priviledges associated with your user account.
pppd: command not found
linuxmintlmde@lmde / $ /usr/sbin/pppd
Plugin /usr/lib/pppd/2.4.5/pppoatm.so loaded.
linuxmintlmde@lmde / $

per far partire il modem non basta impartire il comando pppd, ma devo anche fornire il percorso in quanto, come scritto nell'output, "The command could not be located because '/usr/sbin' is not included in the PATH environment variable."

come includo la directory '/usr/sbin' nella PATH ?
