I'm having a slight dilemma on reading data from a text file and outputting it into a table then displaying it. Basically I'm writing a shell script that takes information from text files then outputs the data into a table with 4 headings.he extracting of the data is fine, but creating a table i'm having problems with. I think it is possible to do it using the awk function, but so far i'm having a lot of difficulties.
View 14 Replies View RelatedWe know that, in a network, data transfer time is dependent on capacity of the receiving node. I have two Linux systems A (sender) and B (receiver) connected. I want to simulate congetion in a network, that means I want to increse the time taken to transfer some data. I believe, I can do this if I can reduce the capacity of the receiver node B. That perhaps possible by decreasing the receiving buffer size of B. How can I change the receiving buffer size of this linux system B?

View 1 Replies View RelatedI have here a Fujitsu-Siemens laptop with Windows Vista on it. The graphical chip of this laptop is damaged in such a way that during boot I can see texts but once the GUI starts it is over. No more picture. This happens with Vista, but also when I boot a live-cd from Ubuntu.The owner of this laptop, not me, wants to buy a new one but would like all data to be saved.I have downloaded the server version of Ubuntu 10.04 (so I stay in text mode) and with the CD I can boot into restore mode. There it is possible to mount the internal hard-disk, after which I can see the data.
But... how do I get it from the disc? How do I setup the network, which I believe is running already, to make the laptop a part of my home network? Now from other computers I can't see this laptop, and I have no idea how to see my computers from this laptop.Or is it possible to burn a CD/DVD in Restore mode. If so how do I do that?
I've created quite a predicament with my desktop installation and would prefer to be able to salvage it instead of having to reformat/re-install Ubuntu.
Quite a lot happened and here's my best recollection:
- My Ubuntu installation stopped working and I could not get the desktop to load.
- I backup up my entire home directory by creating a zip file along with other small zip files. I used Alt + Del + F1 to get the CLI to do this.
- I then did different things trying to get the desktop to load.
- I did a apt-get upgrade, to try and get it to work; this was not sucessful.
- Working through several dependency issues I finally got sudo apt-get ubuntu-desktop upgrade to work, but it did not finish completely. I started to get out of memory errors. I am assuming this was because too much hard drive space was taken up by the zip files I had created
-I could not boot and do anything properly after that. Every attempt to modify the filesystem (to free up space) results in an error "Read Only File System". The root file system was not being mounted and I would see root@none on the CL
- Looking on the boot loader I now have Ubuntu 9.10 2.6.24-generic installed
- I burnt a new installation of Ubuntu 10.4 LTS
- Using Live CD I tried to see if I could free up some space and get the system back to more stable state,
However this was NOT sucessful. I tried to mount my drive by sudo mount -t ext3 <dev> <dir> but I keep getting the following error: error while loading shared libraries: /lib/libsepol.so.1: cannot read file data: Input/output error
how can i open the sosreport after generating it from the systemi need to know how to view the data inside it

I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:

View 3 Replies View RelatedI have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.
How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.
How make, that disc be able to read and write data for all users? I have Ubuntu 9.

I've been using Ubuntu 10.10 for just under a week. Recently, a partition called 'Data' has disappeared, and all my music and documents along with it. The folder is not to be seen in Places or on my desktop. My only way of finding it is to go to terminal. But when I try to open it there I get an error saying I don't have permission to read it. In Puppy Linux and SliTaz I can easily find the partition and read it. What should I do to bring it back in Ubuntu?

I don't have much money to spend on this, but I want to run Debian Linux (I have lots of Linux Admin experience and am right at home with a terminal) or something like that on a small chip which needs to be able to:
Connect to the control computer via ethernet. Get digital or analog data from a GPS module, pressure sensor, etc. Control a few thrusters. Do various other hardware IO functions. Possibly control a robotic arm (this is a long shot, I know). And costs less than about 100 dollars. I have no experience with embedded systems hardware so I really don't know what to buy or where to start, aside from the fact that I heard that this would be a good place for something ARM-related. I am a software developer with time to burn as far as writing the programs to support this goes.

View 2 Replies View Relatedhow to read MS .xlsx file on debian. I have OO running on the box but it can't read .xlsx format.
View 5 Replies View RelatedRemember back in the days of MS-DOS, a file could have 4 different attributes: archive, read-only, hidden, system. As you know, MS-DOS didn't have any user rights or privileges. Files had no owner. If you were at the command line, you could do whatever you wanted, you could change or delete any files you wanted to... so long as they weren't read-only. Under MS-DOS, if you had a read-only file and tried to delete it, you would get an error saying "Cannot delete read-only file". There was a simple remedy to this, just turn off the read-onlyness:
Code:
attrib -r hello.txt
The point I'm trying to make here is that even though you had full permissions over the file, you still had to turn off its read-onlyness before you could make a change. Well I'm trying to do something similar in Linux. Under Linux, the root user has full permissions over every file. But I need to make a particular file read-only so that not even the root user can alter it. I have a few programs on my computer that need to be run as root because they do some low-level networking (raw sockets and the like), and these programs alter my "/etc/resolv.conf" file. Well I need to find a way of making my "/etc/resolv.conf" file READ-ONLY, even for the root user. It doesn't seem as though the Linux filesystem provides a means of doing this, reason being that the root user will always be able to alter any file it wants to. I was thinking though... there's some way I could turn my "/etc/resolv.conf" file into a virtual file of some sort, like maybe I could use some sort of mount program to mount the file as read-only... ?
