[gentoo-user] emerge all packages which depend on P : how to

[Helmut Jarausch]

Hi,

I have a very simple question. How to emerge (update) all packages  
which depend on some
given package P.

I've tried

emerge -uv1 `equery -q d P`

or  emerge -uv1 `qdepends -q -Q P`

but both commands (equery and qdepends) generate a list with the  
version attached like
   app-editors/kile-2.1.3
which emerge doesn't like (unless there is an '= in front of each name)

Is there an easy way to do so without resorting to shell/python  
scripting?

Many thanks for a hint,
Helmut

Hi, I just had a look on eix and figured out that "eix --deps -# -I P"
lists all packages in short for that are installed and have P in their
dependency variables plus the package itself.

Hope to help

How about one of these?
    emerge -1 $(qdepends -N -C -Q P)

    emerge -1 $(qdepends -C -Q P | sed 's/^/=/')

Stripping the version, which you can do with qatom, is not a good idea
because it will only reinstall the newest version of any slotted
packages. Best to use sed to prefix each atom with =

emerge -1a $(qdepends -qQ P | sed 's/^/=/')

Also, the use of -u in your examples means currently installed packages
will not be re-emerged, unless a newer version is available.
