 Posted: Mon Oct 10, 2005 4:51 pm Post subject: Orphan files finder |
 |
|
The following script will find all of the orphan files (i.e. not owned by any installed package) residing in a user specified directory. The script will NOT DELETE any file from your system, it will only produce a list: you can use this list to decide what to manually delete and what to keep. There are reasons for this: for example the /etc/ssh/*key* files look like orphans but it's important to keep them.
Usage example:
# su
# orphan_finder.py /usr > orphans.txt
NB #1: progress messages are printed on stderror, while actual results go on stdoutput.
NB #2: execute the script as root, otherwise it will not be able to read the contents of certain directories.

| I wrote a patch to portage-utils a while ago and posted a reference to it here in the forum. Has not yet been integrated. It allows staying on same partition, mentionning files owned by multiple packages (aka collisions). |
