(don't worry -- once i get all this cleared up, i'll get distracted by something else and move to another project. :-) given the following terminology for packages: available: exists somewhere in the repos new: a package for which there is *no* earlier version installed newer: a package for which there *is* an earlier version installed i think it works like this: $ yum list list all new and newer available packages $ yum list available list all new available packages $ yum list updates list all newer available packages $ yum list "glob" list all new and newer available packages matching "glob" PLUS list all installed packages matching "glob" (weird, this 2nd part) $ yum list installed list all installed packages $ yum list installed "glob" same as "yum list installed" (despite suggestion in man page, "glob" appears to be ignored) is all that about right? some of it is definitely non-intuitive, and it's odd that some of the variations take a "glob" and some don't, even when they have similar functionality. rday
