I want to know that how the break points and watch points work in the GDB. I know the GDB works on symbol table. But would like to know more details of it. How watch points differ from break points.
View 3 RepliesI'm going to write a script that flashes all AccessPoints in our network, with an expect script. Unfortunately the following code doesn't work.
Code:
spawn cat <file> | ssh root@$ip mtd -r -e linux write - linux
cat: invalid option -- o
Try `cat --help' for more information.
So it doesn't understand the pipe thing anymore. Is there a way to get this command working?
I have some variables that are loaded from mysql - in mysql, the line breaks are not indicated by ' or '<br>' or anything -they are just line breaks. the variable is loaded into javascript and then inserted into a <pre> element. the line breaks are not showing up.
pre1 = pre1.replace(/>/g,">"); - this works well, naturally. but how do i get those line breaks to show up as line breaks in a browser?
I've tried many variations of something like:
I have an array with 15 elements, and I want to break it down into three columns. When the array is split into a the three elements - however on the iteration, it does not conform to that structure.
Code:
#!/usr/bin/perl -w
use strict ;
[code]....
I have a large text file with three columns. I'm trying to write a PERL script that splits the file up based on the value of the 3rd column. So every time the third column reads 0, a new file is created and all the data up until the next 0 is found is written to that new file. This should happen over and over until the initial file has been entirely split up.
ex data:
000
2024
2243
2143
96962871
97972878
000
2034
3034
3352
So with the data above, the file would be split into two files:
data_1.txt would contain
000
2024
2243
2143
96962871
97972878
and data_2.txt would contain
230
2034
3034
3352

View 13 Replies View RelatedI tried to summarize the this as best as possible in the title. I am writing an initial value problem solver in the most general way possible. I start with an arbitrary number of initial values at arbitrary locations (inside a boundary.) The first part of my program creates a mesh/grid (I am not sure which is the correct nuance), with N points total, that contains all the initial values. My goal is to optimize the mesh such that the spacing is as uniform as possible. My solver seems to work half decently (it needs some more obscure debugging that is not relevant here.)
I am starting with one dimension. I intend to generalize the algorithm to an arbitrary number of dimensions once I get it working consistently. I am writing my code in fortran, but feel free to reply with pseudocode or the language of your choice.Allow me to elaborate with an example:Say I am working on a closed interval [1,10]
xmin=1
xmax=10
Say I have 3 initial points: xmin, 5 and xmax
num_ivc=3
known(num_ivc)=[xmin,5,xmax] //my arrays start at 1. Assume "known" starts sorted
I store my mesh/grid points in an array called coord. Say I want 10 points total in my mesh/grid.
N=10
coord(10)
Remember, all this is arbitrary--except the variable names of course. The algorithm should set coord to {1,2,3,4,5,6,7,8,9,10} Now for a less trivial example:
num_ivc=3
known(num_ivc)=[xmin,5.5,xmax
or just
num_ivc=1
known(num_ivc)=[5.5]
Now, would you have 5 evenly spaced points on the interval [1, 5.5] and 5 evenly spaced points on the interval (5.5, 10]? But there is more space between 1 and 5.5 than between 5.5 and 10. So would you have 6 points on [1, 5.5] followed by 4 on (5.5 to 10]. The key is to minimize the difference in spacing.I have been working on this for 2 days straight and I can assure you it is a lot trickier than it sounds. I have written code that
only works if N is large
only works if N is small
only works if it the known points are close together
[code]....
So as you can see, I have coded the gamut of almost-solutions. I cannot figure out a way to get it to perform equally well in all possible scenarios (that is, create the optimum spacing.)
I want to get the last term of an unknown-sized text line, by usig the awk command. Is there any variable which points to the last term of a text line ? (obviously, y can obtain that term if i knew how many terms does the line have... i.e. awk '{print $12}' ; if we are talking about a 12-terms text line) I wonder if there is an option like $?, to get the last term.
View 2 Replies View RelatedI have a database with x number of files (192 at the moment, but will vary from time to time). I am going to copy these files to another location on the same server thorugh shell script. Problem with total size of 192 files is approx 900 GB (again this will vary from time to time).
My shell script should calculate the free space available at present in the server on each of the mount point (can be filled till it reaches 95%). Always 5% free space should be available free for future growth.
After calculating, it should prepare another flat file with following details:
We have a program that catalogs to 40 different mount points. The program is fine as long as thier is free space on at least one of the 40 mount points. My boss wants me to come up with a script that will email us daily to know how much overall free space is left. I know I can do a df but I don't know how to combine the 40 mount points into a single disk used/disk free report.
The 40 mount points are /dev/mapper/areaxx, xx being 01 to 40.
I've a question regarding two camera images. Suppose I've detected 2d window coordinate of 8 markers of an object in a scene in one camera and detected window coordinates of 10 markers of the same object on another camera.
I've detected the marker. It was easy. Now how do i know which window coordinates on two cameras are the coordinates of same marker? I mean there are markers captured on both cameras and some of them are representing the same marker in both cameras. I just like to know which ones are same on both cameras. Is it possible to find that out using opencv?

View 1 Replies View RelatedI have a big csv-file wich is not formatted very well. I clean it up with removing a lot of html etc, but some of the lines breaks where they are not supposed to.What I want to do is to check next line, if it starts with 'PX' I don't want to do anything, but if it does not start with 'PX' I want to merge the two lines. That is removing the newline character on line one and replace it with a space.Can this be done with sed? (or maybe with perl or something, but I'm more familiar with sed)I've been looking und the net to find a solution, but to no result.

I saw an interesting distro on Distrowatch, but the *.iso file needed a DVD rather than a CD. The target computer does not have a DVD player, and doesn't warrant spending any money on it. Is there a way to break the iso into CD lengths so I can install it? Or some other trick to get it going?
View 5 Replies View RelatedIm running ubuntu 10.10 with the default gnome. I have dual 23" LED monitors and I would like to take more advantage of my width by breaking up my screens into multiple custom size zones/grids. Basically so I can maximize a window and it only takes up that custom sized "grid zone". I remember there being a windows app to do this easily, but I havent found anything for gnome. Any recommendations? I dont think compiz grids has much flexibility into the sizes/locations of the "zones".

If it does happen again, is there any way to revert to the open-source ATI driver from the command line?
View 9 Replies View RelatedI have probably ranted so much about not being able to remove Ubuntu, how-ever I believe I have found a break-through, allowing me to once again install Windows XP onto my laptop.I was looking through the Microsoft/Windows website for something relating to XP, and I stumbled upon this bad-boy...Apparently it's an .iso for Windows XP! So I read over it and without hesitation, I downloaded it...I was then referred to something that was actually installed with Ubuntu called'Start-Up Disk Creator', which allows me to make an .iso bootable from a pen-drive...
So, because I recently re-installed Ubuntu (It broke after trying to install a game..) via Pen-Drive, I used the Universal USB Creator on the Ubuntu Website and it is quite similar to this..I will keep posted on my possible break-through on removing Ubuntu
Is there a way to break wubi out of its box? As in, resizing /dev/sdX and moving the current partition data onto there? Or would I have to do a fresh-install, and then copy over the post install data? The reason I'm asking is because, The desktop Wubi is currently running on, has migrated into a router(has some epic umph), and its reached its 30GB limit, and I also have the hard drive space to support it now.
