1) fine
2) ~: home directory; /: root directory (file system root, not user "root"). $ is the prompt for non-root users ususally used, can be modified.
3) I don't understand. Adding users creates accounts so they can log in. The users command lists users actually logged in (as does who). So y y indicates you are logged in twice, and nobody else.

LINSMITH(1)						      General Commands Manual						       LINSMITH(1)

NAME
linsmith - Smith charting program, designed for educational use. SYNOPSIS
linsmith [-d opts] DESCRIPTION
This manual page briefly documents linsmith. It was written for the Debian GNU/Linux distribution because the original program does not have a manual page. A more complete manual is included (in PDF form) with the installation. linSmith is a Smith Charting program, mainly designed for educational use. As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation. It's main features are: * Definition of multiple load impedances (at different frequencies) * Addition of discrete (L, C, parallel and series LC, and transformer) and line components (open and closed stubs, line segments) * Connection in series and parallel * Easy experimentation with values using scrollbars * A 'virtual' component switches from impedance to admittance to help explaining (or understanding) parallel components * The chart works in real impedances (not normalized ones) * Direct view of the result on the screen * Ability to generate publication quality Postscript output * A 'log' file with textual results at each intermediate step * Load and circuit configuration is stored separately, permitting several solutions without re-defining the other OPTIONS
This program is mainly designed for graphical use, and therefore does not have many options. A summary of options is included below. -h, -? Show summary of options. -d items Enables debugging. Possible debugging items: l - loads e - elements g - graphics p - printing m - math o - logging AUTHOR
