I've Got A Black Line In My Firefox Address Bar

Hi all,
I have a large csv file which linux sees large amounts of it as one line. I've been trying to break it up with sed, from..
(name,address,etc),(name,address,etc),(name,address,etc) into

(name,address,etc)
(name,address,etc)
(name,address,etc)

each on their own line.. can this be done with sed? And if not what other commands can I use to do it..

Thanks
pulsar..

I hav code for black hole attack in aodv manet and while trying to run it on ns2 Im getting the fallowing error message

Hi folks,

after googling for a couple of days, I get the feeling, this is a common problem. But the usual fix doesn't seem to work for me.

I am trying to install Linux on a separate partition of my Acer Aspire V5-573G. I used the Lili USB Creator to make a bootable USB drive with Ubuntu 12.04 on it.

when I reach the installation menu, it doesn't matter what I choose (start live, install..), my notebook will always freeze on a black screen.

I figured out how to add 'nomodeset' to the grub line. This does bring me one step further (the Ubuntu start screen) but then I get this message:

Code:

ubuntu@ubuntu:^^$ [   20.267422] mei 0000:00:16.0: init hw failure. 
[   20.267558] mei 0000:00:16.0: initialization failed.

After pressing enter I get a command line. From here I don't know what to do.

I've tried other distros (Lubuntu, Linux Mint), but then even 'nomodeset' didn't make a difference. I have also tried to add 'acpi=off' to the grub line after 'nomodeset', but again only black, even with Ubuntu.

Any suggestion or help will be greatly appreciated!

I know that '>' and '>>' will redirect output to a file

However, how does one keep this output on the same line as the previous line?

'echo -n' will stop a trailing new line but for terminal redirection?

Hello everyone,


Although it seems easy, I've been stuck with this problem for a moment now and I can't figure out a way to get it done.

My problem is the following:

I have a file where each line is a sequence of IP addresses, example :

Line 1: 10.0.01 10.0.0.2
Line 2 : 10.0.0.5 10.0.0.1 10.0.0.2
...

What I'd like to do, is to remove lines that are completely matched in other lines. In the previous example, "Line 1" would be deleted as it is contained in "Line 2".

So far, I've worked with python and set() objects to get the job done but I've got more than 100K lines and sets lookups are becoming time consuming as the program goes :/

Thanks for you help

hi,

I am newbie in Linux shell scripting.Can anybody help me to check the presence of file identified by variable in Shell scripting?

For example: I am reading the content of a file using while command as below:
"while read -r line
do
code block
done < file_name"

Now in this case every line in file gets stored in the variable 'line' one by one.Problem here is every line in the file is nothing but the file_path of another file say xyz.txt and I am checking presence of this xyz.txt file using below command:
if [-f $line]
as 'line' is the variable which stores file path of xyz.txt but it is not working. It is unable to check the presence of this xyz.txt file as i am addressing it with the variable 'line'.

Please help me.Thanks in advance.

I am looping through a file and then want to run some commands. Below is my code.

cat $PATHNAME | while read line;
do
PATH=$line
ls -t $PATH/javacore* >$NDIR
diff -w $ODIR $NDIR > $CHGS
done
This is the error I get.
./java_snap_monitor.sh: line 13: ls: command not found
./java_snap_monitor.sh: line 14: diff: command not found

I have a log file with a header (which I can skip with awk), and a footer, which I need to find a way to remove. The goal is to extract the middle lines from a file. Specifically, there is a header (1 line) and a footer (1 line).
The only way I can figure out how to do this is if I already know how many lines are in the file to begin with. For example, if the file looks like this: line 1 (header)
line 2 (interesting line)
line 3 (interesting line)
line 4 (footer)
I just want to extract the middle "interesting lines" without the header/footer lines.
I can't use grep to remove the header/footer, because I don't know what those lines will contain, only that they exist and are exactly 1 line each. In general, I don't know how many lines are in the file.

Hi,

I have been trying to get information on how to process the output of a tcl file (aodv and leach protocol using mannasim) which I got on my command line Iinterface. Actually, I don't even know the keywords to search as I am new to this and other minor attempts haven't yielded positive results., I know there is usually a trace file but I can't see any. All I see is on my command line.

I also observe that it took the space on the entire screen and I can't copy the output from the start ( I could only copy from node 19 out of 30 nodes) because of the huge number of output lines.

The last thing I havent been able to figure ou is whether temperature is equivalent to energy Iin mannasim as mannasim has only temperature and carbon dioxide?


Thanks

I have two files which has exact same number of lines.
I want first line of first file should be filename of new file and content of this new file should be first line of second file.
Then second line of first file should be filename of again new file and content of this new file should be second line of second file.
then third line of first file should be filename of again new file and content of this new file should be third line of second file.
and so on...
I am trying to do it using for loop but I am not able to create two for loops.
This is what I have done
Code:

IFS=$'\n'
var=$(sed 's/\"http\(.*\)\/\(.*\).wav\"\,\".*/\2/g' 1797.csv) # filenames of all files
var2=$(sed 's/\"http\(.*\)\/\(.*\).wav\"\,\"\(.*\)\"$/\3/g' 1797.csv) # contents of all files
for j in $var;
do
#Here I do not know how to use $var2
done

Please help.
