1. Either with the "useradd" command (try "man useradd" to see the manual page which explains how it works), or by directly editing the /etc/passwd and /etc/shadow files.
2. Depends what you mean by privileges - there are ownerships and permissions of files/directories that will define whether a given user can read/write/execute any one of these. Changing ownership is achieved with "chown" (change owner) and "chgrp" (change group). Permissions are modified by "chmod" (change mode). You also have projects defined on Solaris 10 in /etc/project which can be used to group together users and permissions.
3. Again, it depends. On Solaris, most software comes as a package (with a .pkg extension) so can be added with pkgadd and removed with pkgrm (again, have a look at the man pages to get a better idea of how these work - "man pkgadd" or "man pkgrm", but you should be getting the idea of man pages by now :-) . You might also come across other means of installing software, such as running a particular script, or a "make install" command, or you may have to decompress an archive or unpack a tar file. Most software will come with some kind of instructions and if not, your best place to start is by looking at the file extension (the bit after the final ".") If there's no file extension, try "file <filename>" and it will attempt to figure out what kind of file it is by reading the first few bytes of the file and looking for a match in /etc/magic, although this is not only for files without an extension,
dmidecode-2.11: gzip compressed data - deflate method
So I know from this that this is a gz file and I need to unpack with "gzip -d"
