Where do I get the 'update-java-alternatives' command. What package does it come from? My understanding is that you use 'update-alternatives' to initially add a Java instance to your system but once you have multiple instances added you can use the 'update-java-alternatives' command to flip all the symlinks using a single command.

Can anyone provide insight on where I can get this command on ANY Debian system or even a Redhat system?

How do I set Nautilus to use same window on double click when browsing folders? This would be similar to how windows works. Right now, my Nautilus opens a new window of nautilus if i double click a folder. To use the same window I have to remember to nicely click the little arrow icon to expand the folder.

So, is the default behavior changeable?

I've been struggling, trying to get my Mediatomb server to start automatically on Upstart run level 2. I can't figure it out. I guess Upstart is still new to me and I don't understand it. I even read the whole manual and it is vague and never mentions any of the inner workings of how things work.

I can obviously run mediatomb with this command and so getting it to run is not my question:

sudo mediatomb --config /etc/mediatomb/config.xml

or

mediatomb --config ~/.mediatomb/config.xml

I know Upstart supposedly will start services as superuser but what happens when running Upstart commands as a normal user? Do priviledges get escalated? I can't seem to figure it out.

These commands don't work:

service mediatomb start
/etc/init.d/mediatomb start 
sudo initctl start mediatomb (says it started but not really)

To me, this all seems to be some kind of permissions issue but I don't understand enough about Upstart to figure this out. Very frustrating.

me@linux:/etc/init$ start mediatomb
start: Rejected send message, 1 matched rules; type="method_call", sender=":1.58"
(uid=1000 pid=2665 comm="start mediatomb ") interface="com.ubuntu.Upstart0_6.Job"
member="Start" error name="(unset)" requested_reply="0"
destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")

My "df -h" command on my Linux box has some devices with longer names and so the "df -h" output has line breaks (or tabs??) in it, which makes it difficult to parse the output in a script.

Does anyone know how I can suppress the linebreaks so that the latter of the following outputs is what I get:

[root@me ~]# df -kh
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      3.9G  404M  3.3G  11% /
/dev/mapper/VolGroup00-LogVol05
                      3.9G  442M  3.3G  12% /home
/dev/mapper/VolGroup00-LogVol04
                      3.9G  261M  3.5G   7% /var
/dev/mapper/VolGroup00-LogVol03
                      3.9G  137M  3.6G   4% /tmp
/dev/mapper/VolGroup00-LogVol02
                      7.8G  3.6G  3.8G  49% /usr

And the desired format is:

[root@me ~]# df -kh
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00   3.9G  404M  3.3G  11% /
/dev/mapper/VolGroup00-LogVol05   3.9G  442M  3.3G  12% /home
/dev/mapper/VolGroup00-LogVol04   3.9G  261M  3.5G   7% /var
/dev/mapper/VolGroup00-LogVol03   3.9G  137M  3.6G   4% /tmp
/dev/mapper/VolGroup00-LogVol02   7.8G  3.6G  3.8G  49% /usr
