Q: Why root's default shell is configured differently with other normal user account's default shell?
As I know, root's default shell is configured csh and normal user's default shell is sh in FreeBSD. And in Ubuntu, root is dash, normal user is bash. (refer: What's the Ubuntu's default shell?) Why are they configured differently?
I am trying to restore a VM but I get this error message:
I think this happened because, while the VM was live, I removed one snapshot.
How do I fix this, short of restoring older snapshots?
NOTE: I use version 4.0.4.
Just today I decide to place a bounty on an old question, and notice that the count doesn't get incremented.
Is this some form of caching, i.e by design? Or is it a bug?
Can anybody explain(hopefully with a picture), how is the linux graphics stack organised? I hear all the time about X/GTK/GNOME/KDE etc., but I really don't have any idea what they actually do and how they interact with each other and other portions of the stack. How do Unity and Wayland fit in?
First of all, there is really no Linux graphics stack. Linux has no graphical display capabilities.
However, Linux applications can use graphical displays and there are a number of different systems for doing that. The most common ones are all built on top of X windows.
X is a network protocol ...
Hi,
I understand that by default, newly created filesystems will be created with 5% of the space allocated for root. I also know you can change the defined space with:
tune2fs -m 1 /dev/sdXY
What I'm curious about though, is what the actual purpose for this reserved space is. Does it serve an...
Following on from this question about stripping newlines out of text, I want to turn this into a zsh alias as follows:
alias striplines=' awk " /^$/ {print \"\n\"; } /./ {printf( \" %s \",$0);}"'
I've tried escaping the quotes inside the awk script, but I'm getting this error:

Last night, before abandoning my computer for the evening, I started a bunch of compiler jobs so they'd be ready in the morning, using make -f alpha.mak &>alpha.out &. When I came back and hit return, I saw the following output:

I am looking for a solution in which I can add watermark to the given video at given frame.
Is there any utility/tool to do so ?
Circa 1974, you'd sit at a convenient desk and write your program out long hand on paper. You'd test it by walking through it in your head using test data. When you were satisfied that your program was correct, you'd go to the punch card room and transcribe your program onto punch cards, one 80 c...
I wonder what's the origin of root account? Where did it come from and why it's called root anyway?

hi,
because the wireless network adapter does not support bridging, it is really difficult to get the guest vm connect to the open internet and having an ip in the same network as the host. i am using ubuntu 10.10, and the kvm version does not support vde, so it becomes even more difficult...

In response to a comment of mine to this question on SF the OP asserts that the
for i in {1..$NUM}
expands correctly in bash. I have access to bash 4.0.33 (Ubuntu), 3.2.25 (Centos) and 3.00.16(1) (solaris 10). None of these will expand the {1..$NUM}.
Does anyone know which versions of bash ...
Why is the default virtual terminal in ubuntu tty7? is there any sort of precedent for this, or was that just the number that first came to mind?
I use a greasemonkey script to get the desired effect:
It's really simplistic but seems to work fine. source code, direct install link
I'm having real problems having upgraded Ubuntu from 10.04 to 10.10. My main problem is I cannot get a network connection either wired or wireless. When I right click the Network manager applet the Enable Networking check box is greyed out and unchecked.
Any ideas how to resolve this?
Thanks
You can use the tool package-cleanup which is part of yum-utils. Besides finding packages which are not available from the current yum repositories, finding packages with broken dependencies, pruning old kernels and finding duplicate packages it can also find packages on which no other packages d...
I got a Vodafone K3760 at some point in Debian/Lenny's lifetime, for use with a Lenovo S10e. I installed (from the Vodafone BetaVine site) usb-modeswitch 0.97 and vodafone-mobile-connect (VMC) 2.10.01-1 (or maybe it was actually vodafone-mobile-connect_svn20090615) and it all worked pretty well....

I have a USB card reader, an Olympus MAUSB-10. It provides direct flash access to SmartMedia or xD cards, using the Linux alauda driver. This is different from a typical card reader which just exposes it as a standard USB mass storage device.
