Re: su profile


is it '~' or '-' As far as my knowledge goes it should be

su - username

this will run the username's profile once u log in as username. else the su does not run any profile and hence ur current profile remains as r environment

su correction

Dear all,

I do apologize for the errorneous comment. As linuxpenguin correctly pointed out, the argument for [su] is indeed [-].
N.B The tilda [~] (if I remember correctly) is used within a shell, in order for a user to return to his/her HOME directory or to any user's HOME directory.
