Portage one liners
(Hey baby, wanna touch my gentool?)
Here are a few of my favorite one-line commands to make portage do cool and useful things. I've tried to include commands that are usefull and not overly obvious as the man pages for the tools in gentoolkit are very good.
The basic requirements for this How-To are a gentoo system with a recent version of app-portage/gentoolkit installed.
To find out where xchat installed it's executable:
| Code: | | qpkg -nc -l xchat | grep bin/.* |
To find vcron's man pages:
| Code: | | qpkg -nc -l vcron | grep man[0-9]/.* | sed "s/.*man[0-9]\///g" | sed "s/.gz/)/g" | sed "s/\./(/g" |
This is a bit ugly but 99% of the time it will spit out a list of man pages installed (like crontab(1), crontab(5), cron(8))
To verify the integrity of /bin/ps
| Code: | | qpkg -f -c -v /bin/ps |
To verify all installed packages in the meta-category 'system':
| Code: | | for I in `emerge -eDp system | awk '{print $4}'`; do qpkg -c $I; done |
This will take forever as it checks mtimes and md5s for every file of every package in 'system'
To upgrade every package on your system to the latest version:
| Code: | | emerge -Uu --oneshot `qpkg -I -nc` |
This will catch things that even emerge -UuD world will miss without adding them to the world file.
To print info on USE flags that will affect php:
| Code: | | for I in `emerge -vp --nodeps php | grep ebuild | sed "s/\[ebuild.*[0-9] //g" | sed "s/[-,+]//g"`; do euse -i $I; done |
To rebuild your entire system using the USE flags that the individual packages were compiled with:
| Code: | for I in `emerge -eDp world | grep ebuild | awk '{print $4}' | sed "s/\-[0-9].*//g"`
do
USE="`etcat -u $I | grep "\+ [0-9,a-z]" | awk '{print $3}'` `etcat -u $I | grep "\- [0-9,a-z]" | awk '{print $2 $3}'`" emerge --nodeps --oneshot -pv $I || echo -e "$I did not compile" >> ~/emerge_emptytree.log
done |
For every package in emerge -eDp world, the script will use etcat to determine what it was installed with and emerge that package (not touching your world file) using those USE flags. It's set for -p right now so you can do a dry run. If you're sure you like the decisions it makes, remove the "-pv" from "emerge --nodeps --oneshot -pv $I" on the end of line 3 (which should all be on one line)
I think those are the ones I find most usefull. If anyone else uses the gentools in interesting ways, please post. |

i use the patch to show dl times in emerge -vp, so i think that a script as such is better with that:
| Code: | $ cat euseflags
#!/bin/sh
for I in `emerge -vp --nodeps $1 | grep ebuild | sed "s/\[ebuild.*[0-9] //g"|sed "s/[-,+]//g"|sed "s/kB//g"|sed "s/[0-9][0-9]*//g" `;
do euse -i $I;
done
|
dont no how well my sed commands are, but i think itll work w/ or w/o the download time patch. |

Is there a way to recompile the exact version of every installed package? "emerge -ep world" wants to downgrade the packages that I installed with ACCEPT_KEYWORDS="~x86".
Also, where does qpkg get its package information? When I run
| Code: | | emerge -Uu --oneshot `qpkg -I -nc` |
I get:
| Code: | root@mslug# emerge -Uu --oneshot `qpkg -I -nc`
Calculating dependencies \
emerge: there are no masked or unmasked ebuilds to satisfy "app-admin/fam-oss".
!!! Error calculating dependencies. Please correct. |
I cant find any trace of that package anywhre in portage or on my system. |

hey exactly... i getthe same app-admin/fam-oss error, even when i try to do a emerge -pUD world !
Its insane, earlier i used to get virtual/cdrdao error ! and i had to manually fix the ebuild for cdrtools, and cdrdao for emerge to work properly again !
Can someone point us in the right direction this time ?
Bye,
Jassi |

i had the same problem with fam-oss.
qpkg gets its information from /var/db/pkg
the problem occurs because fam-oss was renamed to fam. in some cases a simple re-emerge of the package (in this case fam without the -oss) does work, if it doesn't then you have to get the old ebuild from portage cvs and try to uninstall cleanly.
i also noticed that masked installed programs may become a problem if there is no unmasked version of it. so my sysupdate-script looks the following:
| Code: | | emerge -UD $@ `qpkg -I -nc | egrep -v "(bootsplash|gentoo-test|pfeifer|kahakai)"` |
it just greps out the masked packages.
hope i could help.
btw, what speeks against writing the output of qpkg -I -nc to the world-file? |

Thank you very much for that grep trick! I've been having that problem with "emerge -DU world" for a while and have not been able to find a workaround untill now.
As for adding the output to the world file, I don't think it would break anything. It just makes the update line act more like a regular "emerge -DU world" which wouldn't add anything to the world file. |

That would make depclean (more) totally useless. If you simply put every installed package into your world file, nothing would ever show up for depclean. |

Just replace the part in quotes with the masked packages on your system. |

Why not just do "etcat -u php" ? It's much shorter to type out and the output is much cleaner...

Yes that is a little easier. Did etcat always include deps or have I had a little too much holiday cheer  |

Hey, I want to recompile my system with the same USEs, but etcat does not work anymore. How would you do it with gentoolkit 0.2.0?
