General :: Parse A File And Print Each Line That Ends With Matching Pattern (if The Next Line Is Blank)

Aug 2, 2010

I've written a script to parse a file and print each line that ends with matching pattern, if the next line is blank. The pattern lines are the result of md5sum $i|sed 's/path///g' so that only md5 and filename appear. Here's what I'm using.

Quote:
for fline in `sed -n '/.*.ext$/p' file1`
do
if [ "`sed -n -e '/'"$fline"'/ {n; p;}' file1`" == "" ]
then
echo ""$fline" has no info" >>file2
fi
done

OpenSUSE Install :: Yast Hangs At 99% Downloaded - Aria2c Can't Parse Progress Line [11.3] / Fix It?

Sep 6, 2010

I've just upgraded to 11.3, as a result, the suse-supplied video driver runs very slowly (screen-saver updates about 2 fps, to give you an idea) On 11.2, I had installed nvidia's native driver and things were just fine, so I tried to install the latest nvidia driver again, but I'm getting a hard hang with Yast -- at 99% downloaded, yast stops responding ("abort" doesn't respond, but an external "kill" signal works)

Finally getting the bright idea of checking the y2log file, I see the following code...

these three lines are repeated every second

I'm sure there are some fingers to be pointed [nvidia's ftp server is borked; aria2c is clueless, etc] but that does not help me - what do I need to do to convince this "aria2c" program that the file has, in fact, completely downloaded so that the installation process can continue?

General :: Ubuntu 10.10 And Command Line Scripts - Error - Android: Command Not Found

Mar 26, 2011

I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...

I just installed the JDK, SDK, Eclipse successfully (or I assume):

* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).

** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,

My system:

Intel i7
Ubuntu 10.10 Maverick Meerkat
android-sdk-linux-x86
eclipse 3.6.2

At that time I was connected to the system via putty and wrote the command init 5 and the x server started again normally. I tried init 3 again and had the same thing.
