[gentoo-dev] little function to delete packages ...

[Juergen Ilse]

Hello,

After "rsyncing" und "updating" my system, i wanted to delete old and
unnecessary packages. "ebuild" needs the complete filename of the file
in /var/db/pkg/*/*/*.ebuild to delete the package. I had to type the
full path every time, i wanted to delete an old version of a package ...
So i made a little shell-function (and placed it in roots .bashrc):

delpkg ()
{
    _DBPKG_DIR=/var/db/pkg
    for f in "$@";
    do
        case "$f" in
            */*.ebuild)
                ebuild ${_DBPKG_DIR}/$f unmerge;;
            *.ebuild)
                ebuild ${_DBPKG_DIR}/*/$f unmerge;;
            */*)
                ebuild ${_DBPKG_DIR}/"${f}"/*.ebuild unmerge;;
            *)
                ebuild ${_DBPKG_DIR}/*/"${f}"/*.ebuild unmerge;;
        esac;
    done
}

With this little function, i can simply type something like

	delpkg net-ftp/pure-ftpd-1.0.8-r1/pure-ftpd-1.0.8-r1.ebuild
or
	delpkg net-ftp/pure-ftpd-1.0.8-r1
or
	delpkg pure-ftpd-1.0.8-r1.ebuild
or
	delpkg pure-ftpd-1.0.8-r1

I prefer the 2. or 4. form of this command, because i go to /var/db/pkg
and do for example "ls app-admin" and then something like

	delpkg <...>

with the via "cut&paste" copied names of the packages to delete  (which
i can see in the output of ls) instead of <...>.

Maybe this little function is also useful for someone else ...

ciao,

Hi,

you could also have used 'emerge --unmerge' which support dependency
matching allowing you to for example unmerge every application lower
than a certain version. It also defaults to not erase the latest version
of an application, but letting you have a working version on your system
at all times. Read 'emerge --help' for exact details.

Best regards,

Geert Bevin
