While we're talking about making package handling easier for
newbies, I'd like to present two simple shell scripts that I
wrote quite some time ago. Yeah, I know I could send-pr this,
but I'm not sure if they're really worth it (if someone thinks
they are, then I'll send-pr them).
The first one is "pkg_ls" and it simply lists packages that
are installed. If no arguments are given, it lists all of
them, otherwise the arguments are (abbreviated) package names
to list. For example, "pkg_ls lynx" will list your installed
lynx package, without you having to know which version it is.
You can do this with pkg_info | grep, but remember we're
talking about making things easier for newbies. ;-)
The second script is called "pkg_rm"; it can be used to delete
packages like pkg_delete, but you can use arguments in the same
way as for pkg_ls above (i.e. "pkg_rm lynx"). Think of it like
pkg_info | grep | pkg_delete.
It might more sense to implement these features in pkg_info and
pkg_delete, resprectively, but I don't have the time to do that
(and these scripts work fine, so I have no incentive to bother
with the C sources of pkg_{info,delete}).
