orphaner(8) orphaner(8) NAME
orphaner - frontend for deborphan SYNOPSIS
orphaner [--help|--purge] [deborphan options] DESCRIPTION
orphaner is a neat frontend for deborphan displaying a list of orphaned packages with dialog or whiptail. Packages may be selected for removal with apt-get which is then called to do the work. After removal a new list of orphaned packages is gathered from deborphan. The program ends when either `Cancel' is pressed or no package is marked for removal. After you removed a package, all new orphaned packages are shown at the top of the list separated by +++++ from the old list. Orphaner also shows two additional buttons: `Simulate' and `Help'. `Simulate' does like its name suggest only a simulation of removing and shows the result that would appear after real removing. So you can see the packages, which will become orphaned and you can select them and remove all packages with one apt-get call. `Help' shows you the status of the package given by dpkg -s. Caution: your selection will be lost. OPTIONS
--help Print a short help and exit. --skip-apt Do not call apt-get, but show apt-get command line instead. --purge Call apt-get remove with the --purge option. orphaner accepts most, but not all, options that deborphan accepts. These options are passed to deborphan unchanged, and described in deborphan's manpage. Options which are not accepted include switches to manage the keep file, and switches to change the output format. Note that switches which take an argument need to passed as one argument to orphaner. For instance to only show packages of priority optional and less important, you need to use --priority=optional (i.e. with the = sign, not with a space). SEE ALSO
