But it was still using the environment of the previous user. Now that both users are using the same shell, you have to force the "simulate login" part. Check the output of things like PATH and HOME and what not between your normal user and switching users via: sudo su sudo su - You'll be (mildly?) surprised by the output. :) --=20 Freddie Cash fjwcash@gmail.com --000000000000011e72060a5d8e77 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div dir=3D"ltr">On Fri, Nov 17, 2023 at 10:41=E2=80=AFAM = mike tancsa <<a href=3D"mailto:mike@sentex.net">mike@sentex.net</a>> = wrote:<br></div><div class=3D"gmail_quote"><blockquote class=3D"gmail_quote= " style=3D"margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);= padding-left:1ex">I am trying to bring my environment along from previous v= ersions where <br> csh was the default shell and now trying to get used to sh.
