Which command may be used to change to the root and start a new shell?

That would be the chroot command. Usually when this is used one mounts the pseudo filesystems (/dev /sys /proc) and then explicitly invoke the shell they want to use in the new root environment, like so:

# chroot /mnt/debian /bin/bash

There are other options, refer to the chroot man page. What this command does is tells the current session that / should now be at /mnt/debian and to invoke /bin/bash as soon as the root is set up.

Changing root is primarily used in two ways. One is to effectively set up a rescue environment for Linux from live media so you can use the tools of the target system and not the host system to do your work (Pretty much essential for adjusting kernel stuff/installing bootloaders correctly, the other is actually fakeroot: It's how most Linux package management systems actually work, by creating a fake root tree so that packages have a tree that exactly duplicates the location the files would be in when installed. This way the package manager simply has to extract the file to / to install the files precicely where they need to go. (Most package management has a little more complexity than this, but this is how package managers work in terms of the actual file management.)

What happens when you give the following command mv to do done if the file named done already exist?

the cp command would copy "do" over "done"

if this isn't the behavior you want, you can do "cp -n" to not overwrite if "done" exists, or "cp -i" to prompt you whether you want to overwrite or not.

What command cancels print jobs on a printer?

How many different kill signals can a kill command signal send to a certain process?

How do you install a network printer?

FIRST WAY: This is the cheapest and the easiest way to connect a printer to multiple computers. Simply plug the printer in one of the computers and set it up as shared printer over the network.

Why does 'Error 1068 The Dependency Service or Group Failed To Start' appear when starting the remote access auto connection manager or print spooler in Windows XP?

Best answer is that the registry is corrupted you can do the steps on this page if you can get it to work. Another way is to just download a default services reg file. It will definitely fix your problem, however you may have to reload some programs or reactivate some needed services. It will also speed up your computer processing. You can go to www.blackviper.com and check out the downloads section for your Windows build or go to Windows Support website and check their downloads section for a similar file. This will save you time and headache of trying to get the program (or whole system in my case) to work with no result.

Make sure Network DDE and Network DDE DSDM are started in Services. You can get to services by going to Start, Run and typing Services.MSC
