When I run it I get the portagefiles(15M) and allfiles(8M) in /tmp. But reading the files I find numerous files that I would assume are needed system files, and if not, many that I'm sure I do not want to delete:
I was under the assumption that files listed in these two files were okay to delete, but looking at the output I assume that this assumption is incorrect.
Any thoughts? |
Ah, no, it's the actual output to the console that is the listing of files cruft suggests for you to delete. The files in /tmp are just temporary lists of the files owned by portage and guessed by cruft, and the files on your system in Portage-controlled areas respectively.

Personally I prefer to just put the output into a file, check the file and then use that, but rm -ir `cruft` (or the equivalent built into the script) should be ok (actually, letting people choose whether to have the output displayed on the screen, in a file, or "rm -ir"ing would but a nice thing to put in)

Oh, good thing I didn't do something like "cat /tmp/portagefiles | xargs rm".

Hey, great script. Works great.
I've added the directories and files I don't want to be displayed but one directory, I think, should be added to the default list:
/var/run
All the .pid files in that directory are being shown as files to delete. |

But then it would be my fault. I've seen other people get bitten by this kind of thing.
However, the output is now tee'd to /tmp/cruft-cruftfiles. That might help.

Not all of them.
| Code: | # Explicitly referenced pidfiles
sed ':a;/\\$/N;s/\\\n//;ta;s/^.*start-stop-daemon.*\(\<-p\|--pidfile\>\|\<-m\|--make-pidfile\>\)\s*\(\/\S\+\).*$/\2/;tb;s/^.*pidfile=\(\/\S\+\).*$/\1/;tb;d;:b;s/\s\+/\n/g' /var/lib/init.d/started/*
# Guess some pidfiles
for service in /var/lib/init.d/started/*; do
echo /var/run/${service##*/}.pid
done
for service in /var/lib/init.d/started/net.ppp*; do
echo /var/run/${service##*/net.}.pid
done
|
Any extra that belong to running services, please tell me about. Thanks.

The script gave me 4400 files to delete ( ), the only ones that might be false are the following from aMSN:
| Code: | /usr/lib/amsn/plugins/traydock/Makefile
/usr/lib/amsn/plugins/traydock/Makefile.in
/usr/lib/amsn/plugins/traydock/README
/usr/lib/amsn/plugins/traydock/config.h
/usr/lib/amsn/plugins/traydock/config.h.in
/usr/lib/amsn/plugins/traydock/config.log
/usr/lib/amsn/plugins/traydock/config.status
/usr/lib/amsn/plugins/traydock/configure
/usr/lib/amsn/plugins/traydock/tray.c
/usr/lib/amsn/plugins/traydock/tray.o
/usr/lib/amsn/plugins/traydock/traydock |
I have aMSN installed but just removed Gnome and switched to a -gnome USE flag. These traydock files could be Gnome related but I didn't want to delete them just in case.
Thanks a lot.

very nice, thanks.
there are a couple things listed that shouldnt be, though:
1. it lists the whole contents of /usr/share/xmms/Skins (i have xmms installed, though)
2. apparenty it doesnt like the icons i put in /usr/share/pixmaps. maybe this is due to a fault of mine, tho. is there a better place to put those?
3. is it supposed to list this?
| Code: | /etc/gentoo
/etc/gentoo/gentoogtkrc
/etc/gentoo/gentoorc
|
4. it lists /usr/bin/TeamSpeak although i have ts installed. i dont exactly remember if that binary was installed normally, i might have had to put it there manually or something.
5. /usr/bin/kill <- i really think i need this...
6. it lists a whole load of perl5 and python2.2 stuff. i dont really feel comfortable deleting that. how do i find out what version of perl and python im using?

It works great, but I have a feature suggestion: --exclude=/dir
That way the user doesn't have to open the script to add special mountpoints and so forth. (Yes, I know... not following the LSB, but I like having my stash partitions under /stash instead of /mnt/stash  |

Installed with x11-themes/xmms-themes or by hand?

/usr/pixmaps/local | Quote: |

| Code: | /etc/gentoo
/etc/gentoo/gentoogtkrc
/etc/gentoo/gentoorc

I don't have that, use my cruft-blame.py to work out what put it there | Quote: |
4. it lists /usr/bin/TeamSpeak although i have ts installed. i dont exactly remember if that binary was installed normally, i might have had to put it there manually or something. |
I don't think TeamSpeak is in Portage; if not it should be installed to /usr/local/bin or /opt. | Quote: |
5. /usr/bin/kill <- i really think i need this... |
But you have /bin/kill, don't you? | Quote: |
6. it lists a whole load of perl5 and python2.2 stuff. i dont really feel comfortable deleting that. how do i find out what version of perl and python im using? |
perl -V, python -V.

Actually, cruft now tees its output into /tmp/cruft-cruftfiles.
To rm each line, use "cat file | xargs rm".

oh, and the xmms skins i have are manually installed, not emerged. i prefer putting them in the shared theme directory instead of the user's one.

The skins you use... would it be possible to switch to using the ebuild or does it lack some skins you need? I'm weighing up adding /usr/share/xmms/Skins to the exclusion list but I would need to be persuaded that this is the best solution.

there is no "the ebuild", as the xmms-skins ebuild sucks pretty hard. the skins on my systems are all from www.winamp.com, customize.org or deviantart (ah, i love winamp compatibility). i'm pretty sure that is the way most people do this (although some people probably put ~/.xmms/Skins/). however i can't really think of anyting in /usr/share/xmms/Skins/ that would neet to be removed.

Here's the files is identifies wrongly:
/var/run/cron.pid (vixie-cron)
/var/run/klogd.pid (sysklogd)
/var/run/syslogd.pid (sysklogd)
/etc/gentoo-release (Gentoo release file?)
/usr/lib/python2.3/lib-dynload/bz2.so (hmm.. Don't want to delete this I don't think)
This is from a clean install. Just finished the install, restarted, ran cruft script.
Edit:
/var/log/news/news* (startup complains about not being able to find them)

Hello!
Another great script of yours, thanks for that!
FYI here are the changes I've done to get zero false positives (as a diff against version 0.0.10):
| Code: | 285a286
> /initrd
288d288
< /opt
289a290
> /usr/opt
347a349,352
> $(has_version dev-java/blackdown-jdk \
> || has_version dev-java/sun-j2sdk \
> || has_version dev-java/sun-jdk \
> || has_version dev-java/ibm-jdk && echo "/etc/.java")
373a379,380
> /etc/ntp.conf
> /etc/ntp.conf.sv
444a452
> $(has_version media-libs/gle && echo "/usr/X11R6/include/GL/gle.h")
445a454
> $(has_version media-video/ati-drivers && echo "/usr/X11R6/include/GL/glxATI.h" )
470a480
> /var/run/cron.pid
532a543,547
> has_version dev-util/eclipse-sdk \
> && PRUNE="${PRUNE}
> /usr/lib/eclipse/Uninstaller
> /usr/lib/eclipse/features
> /usr/lib/eclipse/plugins"
549,550c564
< /etc/bootsplash/default
< /etc/bootsplash/gentoo/images/.directory
---
> /etc/bootsplash |
/initrd is added at boot time since I installed bootsplash and hence activated the initial ramdisk. I don't know much about these thingy. Does anyone know, if I can inhibit this or at least convince it to show up in a more appropriate place like e.g. /media/initrd?
I removed /opt from the prune list, 'cause everything I have there (Acrobat, JDKs, OpenOffice) is administrated by portage and I wanted to have that checked for cruft, too.
But on the other hand, I added /usr/opt, which is the "real" place of these. (/opt is just a symlink, because I chose a relatively small root partition and a large /usr and, hence, the /opt things should also go on that partition.)
Do you know a more elegant and/or FHS-conform way to do that?
BTW, does cruft follow symlinks? Or is the /opt hierarchy not checked in the setup sketched above?
/etc/.java is generated everytime I start a Java application as root, and if it's not there and I start it as ordinary user, the application complains. So I guess, it has to be there.
I don't know, where /etc/ntp.conf and /etc/ntp.conf.sv come from (I do not have ntp installed, but they are regenerated, if I delete 'em), but I would guess, that it has something to do with samba, 'cause the IP restrictions are somehow similar.
Does anybody know?
/usr/X11R6/include/GL/gle.h and /usr/X11R6/include/GL/glxATI.h have to be pruned, because the ebuilds install into /usr/include/GL, which is a symlink to /usr/X11R6/include/GL. I guess the glut entry, that was already there has the same reason.
/var/run/cron.pid was not guessed by the script, I don't know, why.
The Eclipse entry is there, because I'm using a UML plugin, which is not in Portage and I didn't want the files (a _lot_) to show up in the cruft output.
Finally, I modified the bootsplash entry, because my handmade bootsplash configuration and a downloaded one were showing up as cruft, and I thought it would be best to ignore the whole directory to allow even more different configurations, as long as bootsplash is installed.
Perhaps, you want to include one or the other, or otherwise point me to why these solutions are not good.
Regards, sean |

OK... um, /var/log/news/news* - do you know what package that belongs to?
