发现个好东西──又一清理系统的工具

soloforce

由第三方写的一个脚本，用来清除多余的（不被依赖的、陈旧的、不必需的）包，也可以用来
整理 world 文件，使之更干净。我试了一下，感觉很不错。

[color="Blue"]Edit: this script also now contains an "emerge depclean" that actually works, an "emerge prune" that actually looks at your dependencies, and a "qpkg -q" that isn't horribly broken!

A world file (/var/cache/edb/world) with lots of entries is no good for keeping your system clean and running smooth. Of course you need to go through it now and again to remove apps you don't want, but the job's easier if it contains as few 'extra' packages as possible i.e. packages that are actually deps on other packages.

Download: http://catmur.co.uk/~ed/main/my-bin/dep

dep v. 0.3.00 "Level Of Incompetence"
an inappropriate Portage engine!

Usage: dep [OPTION]... [PACKAGE]...
List dependencies and reverse dependencies of packages, and clean the world
file and the set of installed packages.

Task selection:
-h, -?, --help Display this help
-P, --purge Unmerge unneeded SLOTted packages
-d, --depclean Unmerge all unneeded packages
-l, --list-depends (default) List dependencies of PACKAGE
-L, --list-raw-depends Display the dependency strings for PACKAGE
-r, --list-rev-depends List reverse dependencies of PACKAGE
-w, --pruneworld Remove redundant entries from the world file

Options:
-b, --no-build-time Omit dependencies needed solely to build PACKAGE
-o, --original-depends Calculate dependencies as when PACKAGE was merged
-a, --ask (default) For -[Pdw]: ask to perform action
-f, --force For -[Pdw]: perform action without asking
-p, --pretend For -[Pdw]: show what action would be taken

A package is unneeded if there is no installed package that depends on it.
An entry in the world file is redundant if there is another installed package
that depends on it.
When merging the new world file, the merging program used is sdiff(1).
Your world file is located at /var/lib/portage/world.

And here's some sample output:

1. 
   
2. # dep -w
   
3. !!!REDUNDANT!!! app-admin/gkrellm depended on by:
   
4.         x11-plugins/gkrellflynn-0.6
   
5.         x11-plugins/gkrellmoon-0.6
   
6.         x11-plugins/gkrellmss-2.3
   
7. app-admin/syslog-ng
   
8. !!!REDUNDANT!!! app-editors/gvim depended on by:
   
9.         app-text/vim-latex-1.5_rc1
   
10.         app-vim/info-1.7-r1
    
11. app-editors/nano
    
12. app-emulation/wine
    
13. ...
    
14. x11-themes/mplayer-skins
    
15. x11-themes/nautilus-themes
    
16. 
    
17. 145 packages in worldfile: 137 valid, 8 redundant; 70 packages in system.
    
18. 563 packages installed: 12% in system, 25% in world, 63% deps.

好像没这个功能，不过已经足够强大了。

清理distfiles我以前从官方论坛下的一个[color="Blue"]脚本，很好用，再贴一下

下载后去除txt扩展名，用root直接运行distclean, 输出将被删除的distfiles，但只有加 [color="Red"]--pretend 参数时才真正执行删除动作：

1. 
   
2. ~ # distclean
   
3. Determining available tarballs in /usr/portage/distfiles ...
   
4. Determining stale versions ...
   
5. *Pretend* mode, will only pretend to delete files.
   
6. [color="Blue"]To actually delete the files, reinvoke with the [color="Red"]--nopretend [/color]parameter.[/color]

好家伙，清理了整整1个G的旧文档。
相当不错的脚本。谢谢分享。

pointer

"No stale distfiles have been detected on your system!"

dep不能用, 说有语法错误
