Programming :: Using File1 As List Of Objects To Search For In File2?
Aug 30, 2010
The goal is to auto-update a webpage that contains links to network devices. These devices are all set to DHCP, and their hostnames are not guaranteed to stay the same, so static IPs or accessing via hostname is NOT an option.
Process: Run a script every hour or so to query devices on the local network to generate a list of responding devices by MAC address and what their current IP is (results.lst). Using a "static" MAC address list file "printers.db" as the database search "results.lst" to find specific MAC addresses. When a match is found, grab the IP from "results.lst" and update "index.html" with the new IP address. No comparison needs to be done between "results.lst" IP and "index.html" IP as I just want to overwrite whatever is there.
Here is what I have so far (using dummy data): PRINTERS.DBProduct Mac Address Printer1 00:00:00:00:00:11 Printer2 00:00:00:00:11:11 Printer3 00:00:00:11:11:11 Printer4 00:00:11:11:11:11 Printer5 00:11:11:11:11:11 Printer6 11:11:11:11:11:11 TEST.SH
Code:
#!/bin/sh

I'm working on some code where I have two files. I know I can use cat file1 >> file2 to append file1 to the end of file2. What I was wondering is how I could append the first line of file 1 to the end of the first line of file2, then the second line, and so forth.
So if file1 was :
cat
dog
mouse
file2:
orange
red
blue
I want file2 to be:
orange cat
red dog
blue mouse
Also I need it to remove any duplicates from the same horizontal line.

I'm learning Bash and can't find how to say "if file1 exists and file2 exits then...".I thought this may work:
Code:
file1="/root/file1"
file2="/root/file2"

how I can merge the data from file1(data per line) to the end of line of file2. So what I mean is, I want to add every line from file1 to the end of the corresponding line of file2.

I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.

I have it so that an Env object contains all the variables in the current scope, and the parent scope. You can also save them to variables like objects, and my idea is to use the "." operator to get values from them.
First, how do I assign to them? I currently have it that only a variable name can be assigned to, but you should be able to assign to an "obj.value" expression, too. How do I keep track of what variable to set and still be able to say it in an expression and have it evaluate to the variable?
Second, these object don't really have a "type", they're just containers that contain any values you want under any name you want. How can I, for example, define a primitive "boolean" object and have things like if statements recognize it?

I have a question about shared objects and when mapping and linking is established in the following code...Well more of a verification.
getsetx.c - shared object source code Code: unsigned long x = 0;
unsigned long getx(void)
{
return x;
}
[Code].....
Now its my understanding when I execute ./testit, getsetx.so will get mapped into its address space at start up and testit will link any functions as they are needed..

I have two classes, for argument's sake A and B. A implements the core functionality, B is an encapsulated data structure. If you imagine this situation
[code]...
From within B's member functions, I would like to access the public function() in class A. This is not an inheritance issue, they are two discrete classes with radically different functionality. Class A makes an object of B.

I am trying to make a hash of objects in perl (long story.) I have a package containing the main hash and all the subroutines necessary to work with it. My "new" subroutine used to add an object to the hash goes like this:
Code:
$tmpdir="/tmp";
$subdir="/AutoScript";

I have created an object where I pass a string and a long value to it <in Java>, currently I am adding the values to my Object so I can then add it to a list like so:
Code:
List myList;
ImageObject io;
for(i = 0; i < 10; i++)
[code]....
This is what the object currently looks like:
Code:
public final class ImageObject<name, time>
{
public String name = "";
public long time = 0;

Using: Open SUSE 11.0 64 bit, KDE 3.5.9 (release 49) and KDevelop 3.5.1. Problem: A singleton was created in subproject A, and so an object file is created in subproject A. In subproject B, I want to use that object file. We have not been able to find a way to link that object file created in subproject A with subproject B. Also, the subprojects are in different directories. We created a symbolic link to the ".h" and ".cpp" files in directory A. And the project compiles and links just fine after adding the symbolic link to the header and cpp files in subproject B. My concern is, that two objects of that singleton will be created. The whole idea of making a singleton is so that there is only one instance at a time.

does the assignment operator copy all the members also for structures containing STL objects strings,vectors,vectors of vectors...)? I did try it on my platform,and it works that way (copying all the fields),but i was wondering if it is a standard behavior or not.

I wish to add information to one of my files based on matching IDs,
Here is an example
(the id is the 3 colunm)
(the ID is the 2 colunm)
And the output i wish to be
OUTPUT:
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.
I thought about using join but that only seems to join the ones that match displays thoes only. i would like all the information in the output file.

I have realized that in not installing suggested packages I've missed out on a ton of doc files, which would really come in handy while I'm away from internet access.
Is there a way take a list of currently installed packages and find out which of them have doc packages available? Possibly install them in a single step? I have been playing around with aptitude and apt-rdepends, but I'm not quite sure how to go about this. Somehow take a list of installed packages, run it through an apt-cache search, and end up with a list of -doc packages to install? My bash-fu isn't the greatest, and I suppose this could be a bad idea to begin with.

A search engine for software only would be nice. Member Craigevil maintains a huge list of repos here:
[URL]
Might it be possible to search them all at once? Perhaps by adding them all, OR MOST of them, to /etc/apt/sources.list?

I feel there's a bit of a misunderstanding going on between C++ and me...My problem is that I have a deque of pointers to a class, and create objects then add them to the deque in a for loop. However, the destructor is called on the object as soon as the loop quits.
Code:
This prints:
Code:
Now, if I change the deque from deque<Test*> to deque<Test> then it works fine - I get:
Code:
However, I can't do this with my actual code, because I am creating a deque of pointers to an abstract class, so it won't let me instantiate the class. (This is all so that I can take advantage of polymorphism, and call functions on a set of similar objects without worrying what type of object I'm dealing with).
So, I suppose my question is: what is the correct way to create that deque of pointers to the abstract class? I don't seem to be barking up the right tree currently.

I want to create a "Shared Memory" in linux, then create multiple "Shared Objects" that can access to a Table for example; And one of them can write something into the Table and the other can access and read it, so that these operations can be handled by programmer! I'm using Ubuntu 9.04 and I've set it's runlevel at 3 (I have commandline environment now!) I've searched the Internet so much, but couldn't find a good sample code for this! I have no experience about it and need your help to introduce me a sample code about it and advise me how to compile and use it with "GCC"?!

How can i use grep (or any other command) to check for lines that begin with N number.
E.g. I want to print out commands (from history), but only from the command number 50 until #200.
This one doesn't work:
Code:
history | grep "^[50-200]"
Should print out something like:
Code:
50 cd ~/Desktop

Code:
Title=
echo -n "Title: "
[code]...
hey guys, im doing a simple search program and i came up with a problem. What i am trying to achieve is, if the search is false(means the book does exist) , the program will then ask the user to input the information again(title and author) and do a search again until there is no such book and then display a message saying he can input a new book in.i tried using a until loop, but it does not seem to work. some guidance on how the statement should be and where should it be placed?
