orphans

yankees26 · 2006-12-06 21:11:04

I made a slight change that only prints out the package name so that way, the results can easily be passed to pacman. For example, now you can do:

pacman -Rn `orphans`

Here it is at pastebin.archlinux

You mean there ain't no builtin way to do this? That's important!

What is "this"?
BTW, Pacman 3 does print only real orphans when using -Qe.

kamagurka · 2006-12-17 16:06:17

"This" is killing all packages that were installed at dependencies for packages that don't exist anymore.
And if pacman does that, why not just add an option to remove those packages in one fell swoop?

Erm, maybe it is my browser, but backslashes seems to be missing from the script... I think this might be connected to the forum conversion?

I entered the code again. Looks like it's fixed now.

pt-orphans doesn't handle "Provides:"
Example: amarok-base requires amarok-engine; package amarok-engine doesn't exist itself, but e.g. amarok-engine-xine "Provides:" amarok-engine (just check pacman -Qi amarok-engine-xine)
pt-orphans in this situation includes amarok-engine-xine as an orphan. I don't know perl enough to fix it...
Not much trouble, but I wouldn't recommend doing 'pacman -R `pt-orphans`'.

Yes, you have a point. I've made a new version that has this logic:
if pkg was installed as dependency and not required by any other pkg:
1. provides nothing => orphan
2. provides "someting" => test if any pkg depends on "something" => if not => orphan

And I translated it from perl to shell.
Please try it:

Same fonction as yaourt -Qt:
Look at the code, it's a litte bit easier:

PACMANROOT="/var/lib/pacman"
for pkg in `ls "$PACMANROOT/local/"`; do
    if echo $(cat "$PACMANROOT/local/$pkg/desc" 2>/dev/null) | grep -q "%REASON% 1"; then reason=1; else reason=0; fi
    if echo $(cat "$PACMANROOT/local/$pkg/depends" 2>/dev/null) | grep -q "%REQUIREDBY% %CONFLICTS%"; then requiredby=0; else requiredby=1; fi
    if [ $reason -eq 1 -a $requiredby -eq 0 ]; then
        version=$(echo $(cat "$PACMANROOT/local/$pkg/desc" 2>/dev/null) | awk '{print $4}')
        orphans[${#orphans[@]}]=${pkg%-${version}}
        echo -e "${COL_YELLOW}${pkg%-${version}} ${COL_NORMAL}seems to be safely removable"
    fi
done

note: yaourt shows automatically new orphans after "yaourt -Rcs" command

Speek · 2007-02-07 12:55:28

I don't understand your code.
grep "%REASON% 1" desc
grep "%REQUIREDBY% %CONFLICTS%" depends
will never match a line in those files.
But I will try yaourt later. I'm in a hurry now.

Speek · 2007-02-07 15:05:07

Well, I don't understand how it works, but it does work The echo and cat thing probably removes the newlines (\n).
But your code doesn't include the issue with "Provides" that bender02 pointed out.

bender02 · 2007-02-20 01:58:58

Sorry for the delay - forum's notification doesn't work the way I expected. So I tried, the new orphans.sh works well, but yaourt (great utility, though) doesn't handle the issue I mentioned above (in my example it would remove amarok-engine-xine).

@Speek - thanks for the script!

japetto · 2007-03-23 00:04:08

Thanks Speek, script works great.

semeion · 2011-05-15 19:06:56

This script still working with the new pacman?

I can´t put this script working here...

hauzer · 2011-05-15 19:12:18

pacman -Qdt does the same. And you're bumping a four years old thread.

ngoonee · 2011-05-16 03:52:01

Closed. @semeion, its good that you search for threads, but if its 4 years old its pretty certain everything has already changed.
