General :: Adding A Comma To The End Of Every Nth Line In Vi (or Sed)?
Oct 12, 2009I have a fairly long list of data that I am trying to put into a math program (maple) but before I can do that I need to edit the format of the data such that at the end of every 25th line I add a comma. I would prefer a solution that uses vi, but if that's impossible sed would be fine also (or awk).

Programming :: Adding Line From File1 Into A Line Of Another File Based On Maching IDs

Here is an example

So as you can see the ones that do not match are still present, and the ones that do match just have the extra information from file2.txt added to them.

Sep 3, 2010Couple of days I go I setup VLC using Kubuntu's graphic software manager, and installed the 3 plug-ins, one of which was related to pulse. After doing this sound stopped working in flash videos. I had read, not sure where, that Kubuntu didn't use pulse (which slipped my mind when setting up VLC).
So I make the mistake of removing everything which had pulse in it's name (again, via the graphic software manager). A message popped-up saying that some packages needed to be removed/edited (a LONG list, a big clue that I was doing something stupid I guess). I let it run it's course and after that it won't boot properly.
If I boot it normally it hangs at the Kubuntu screen with the five dots filling endlessly. If I press F1 it's stuck at "checking battery status."
Recovery mode boots, but the recovery option does nothing.
So I was wondering if I could boot into recovery mode and go into the terminal and add a live USB as a repository for apt, and try to salvage the install?
Or should I admit defeat and reinstall?

Nov 5, 2009- Off a vanilla F11 livecd install, I stuck a 3 at the end of my grub line to boot into runlevel 3. I have been doing this for as long as I can remember (since Fedora 3). However now it seems to break and gives me a GRUB error. I press e to edit, and delete the 3. BUt it still throws and error?!?!?!?! Has this facility (ie sticking a number at the end of the grub line) been changed and why is my grub line now broken even though I've gone back and deleted the 3?
- If I install Fedora 12 beta now, will yum take me all the way into production when it goes live (assuming no killer bugs encountered), I'm guessing thats a yes?

General :: Appending To The Current Line In A File Instead Of Creating A New Line?
Apr 1, 2011I am combining data from a couple different input files and creating an output file in a specific format. I notice that if I use the >> operator, information gets appended to a new line in my output file. This is useful, but if I'd like to append onto the CURRENT line, is there an easy way to do this? I've been googling around and see lots of complicated answers, nothing that suggests to me an easy way to do this. For example, if my output file looks like this:
b1a:] cat test
hello my name is
b1a:]
and I'd simply like to append "Bob", how can I do it? If I use
b1a:] echo Bob >> test
b1a:] cat test
b1a:] hello my name is
Bob
b1a:]
So what I would prefer is some command that would create the result:
hello my name is Bob
