owner 1058 group 103 ?
 

After downloading the win32 codecs from mplayer I moved the tar.bz2 to /tmp and uncompressed with tar -jxf (as root).

Before running the tar command /tmp/all-20050412.tar.bz2
-rw-r--r-- jeff users
The uncompressed directory /tmp/all-20050412/
drwxr-xr-x 1058 103

What causes this and what does it mean? My plan was to uncompress in /tmp and move the codecs to /usr/lib/win32
I'm working in Slackware if that makes any difference.

It just means that the person who created the archive had a user id of 1058 and a group id of 103 on their system. You can change this to a user/group (e.g. user muddy and group blues) that exists on your system with the following:

Thanks gilead. With all the people downloading these codecs from mplayer I would of thought this question would come up more often.

Murphy's law being what it is - other people will have that problem after you and read your post instead of you being able to read theirs ;)
