 Posted: Sat May 04, 2002 12:14 pm Post subject: Portage features? |
 |
|
I am looking to extract the following pieces of information from portage, either through existing commands or by rolling my own (in which case I need to know where the data is to be found).
1. What packages are installed on my system?
2. What are the dependancies for a particular package?
I wish to build something which will allow me to browse my installed packages (rather than "emerge search"ing each one). Once I have compiled a list of those I wish to remove I want to check which packages depend on them...
Thanks
MP

You can emerge epm to find out what packages you have installed:

Personally, I haven't used epm, I find that gentoolkit tells me everything I need to know.

Looks like someone forgot to set the HOMEPAGE variable in the ebuild on that one.

The best way to do this (as far as I know, other then looking at the ebuild) is to tell emerge to run with an --empty-tree. Example: | Code: |
# emerge -e gentoolkit -p
These are the packages that I would merge, in order.
Calculating dependencies ...done!

That shows all the other packages required to statisfy the dependencies of gentoolkit. Note the -p for --pretend flag, we don't want to actually compile all these
Gentoolkit also includes etc-update which is very handy for updating your config files.
Hope this helps.

All information related to installed packages on your machine is in this folder:
/var/db/pkg
It contains more information than any command may produce. |

That's what I was looking for, thank you. I can now bust out x number of scripts to extract exactly what I want to know.
