How do I set a path for jason?
You use your favourite search engine
Normally, when you add a new user, their PATH will be set up to be the default for non administrative
users. This is usually determined by the entries in /etc/skel
("skel" = "skeleton" = bare-bones defaults), that you can customise there, and they will then be copied to all new users home directories when new users are created, to be executed when they login, so they get their environment set up properly. The environment is quite complex. To see yours, try the command env
If your default shell is bash
once new users have a skeleton .bash_logout .bash_profile
copied to their home directory, you (or they) can then customise them individually on a user by user basis.
I suspect that you have added the new user "jason" in an unusual way, because these defaults are usually set up "automagically" by the "create new user" scripts of your distro (which, by the way is not in your profile, please add it). You'll probably also have to make sure jason is a member of the correct groups.
Usually, adding a new user goes something like this (with KDE):
K-System-Users-Add new user-Defaults-Add a couple of extra group memberships, depending on your setup, Done.
