Also, please consider these: dpkg -l \*expr\* displays all packages mathing the glob (shell wildcard) pattern. dpkg -l '*' displays info about all packages. dpkg --get-selections shows all installed packages. dpkg --get-selections '*' shows info about all packages (like `dpkg -l '*'), but in a format that can be fed to `dpkg --set-selections'. This is handy when you want to clone a machine's installed package list [1]. apt-cache search <expr> displays all packages that match <expr> (the match can be in the name, description, etc.). apt-cache show <pkg> shows information about the package <pkg>. apt-cache showpkg <pkg> displays nuts and bolts info about <pkg>. [1] If you only feed `dpkg --set-selections a list of packages to install, dpkg will also install all packages in base, as well as all required packages (IIRC, someone please correct me if I'm wrong). -- Nathan Norman - Incanus Networking mailto:[EMAIL PROTECTED] Never tell people how to do things.
