I am very new to Linux and am taking a class on Introduction to Linux, but I am not familiar with Command Script. Can anyone direct me to a place where I can find more info (for a two year old) on command script programming? I want to be able to understand what it all means.

To prove I'm not going mad I screen captured a short video of the display changing while all I was doing was pressing F5.
The system is set to a European timezone i.e. both date and hwclock commands show 'CET'. There was an update to the Debian tzdata package which I installed at the beginning of February 2010. I'm not aware of there being a problem before that but I could be wrong about that.
I am trying to find a linux cmd line utility that will read info from an iso file. The problem I have is that the file is always corrupt so I cannot mount it because I only have around 100k of it but all I need is to extract the headers of what the iso contains. how I can achieve this I have searched the internet with no look at all.

View 2 Replies View RelatedI've been searching high and low for a solution to my problem, and have not had much luck as to yet!The situation is: I have two files containing bits of info that both need to be included in a single command, such as a for loop, but as separate elements. What I need to do is basically this:Code:ssh <servers in list a> ls -la | grep <items in list b>Does anyone have any thoughts on how I might do this? Is it possible to do using bash scripting alone?
View 3 Replies View RelatedI cannot install Kubuntu 8.04LTS. When I run the Live CD and click to install it gets me the box that should show me my hard drives and possible partitions but the box is empty. I get the same when booting to the Live CD and clicking on install. I have had this CD since Kubuntu 8.04 was released. So not knowing what might be wrong I figure I will ask here for what to type in a command line to install it. I know it is an old version but it is the last one with KDE 3.5.

View 5 Replies View Relatedhow to work properly on the windows forms application in c++.
the thing is that i was able to produce in the windows forms application a web browser and I added a save button. So know I am able to navigate predeclared webpages such as [URL]and then I entered google's search box such as "spread of H1N1". and I surf a page such as [URL] I later save the page as text file on my computer.
I wanted to know how to organize the words in the text file ? i mean how can i just get the number of infected people in USA , number of infected in CANADA (if they exist) from all the text file and change it to a file with precise data.that is to eliminate the unneeded information such as the the characteristics and the useless ideas? and what if i also wanted to know the characteristics of the virus in a country+the number of infected?.

View 1 Replies View RelatedI'm doing this manually, as I'm at work, and if I spent 2 days trying to figure out a script to do this they'd maybe take it as me not working and instead messing around. However what I want to do is pull the:
Contact name, Company Name, Address, City, County, Postcode and email from the whois info for a list of about 400 domains we own.
I think I need some kind of combination of dig, sed and awk to pull the info, then filter out the parts I need, however I've never done anything like this before so I need some advice on where to start.
I'm not looking for a full bolown solution, I already have the list of domains so I think it will be something like:
Code:
for x in {list of domains}{
dig x;
somehow grab name, company name, address,
write to file in csv
}
Am I looking at this in the right way, can someone get me started? Is it sed/awk I need or is there another too.
so i cannot install anything because update-info-dir file is missing from /var/lib/dpkg/info/ ..

View 9 Replies View RelatedI can't remember what it's called, but this feature of VC++ basically catalogs all the functions of a project, lets you right click on a function and go directly to it's declaration or definition, do not pass go, do not collect 200 dollars. it also gives you an info bubble of the variable types as you're typing a function's name.
this is a very convenient feature, and I'd like to use it with KDevelop, or really any full C++ IDE for linux. does such a thing exist?
I am developing an application whose executable is generated inside a certain folder hierarchy (say: /DevPath/MyProject/bin). My source code is located in a different branch of this hierarchy (say: /DevPath/MyProject/src). When my app crashes, its core files are stored in /DevPath/MyProject. I'm developing the app on a pc, but running it on a separate platform in which i can only execute it. Folder hierarchy is the same as above on both computers. Usually, when a new executable version is ready, we update both the executable and the source code on the target platform, transferring all the new /DevPath/MyProject folder on it. But sometimes it can really be a bother, so we update only the executable.
1)In the case we only update the executable, keeping an old source code version, and the app generates a core file, can i trust the backtrace produced by gdb in this case? I.e., does gdb need the latest source code files or it just needs the debugging information?
2) (More radical question ) Do i really need to keep the source code on the target platform for core dump analysis or i just need the executable?
I'm a linux newbie and scripting novice and I'm trying to pull auditing info and dump it into a file. I made some login changes so it would get audited but I don't want to have to sift through the log to see who the user was and what was done. This is what I have below here and I can't seem to get it to extract the info want using the event id. The "ausearch -a $10" from the script should get it from the 10th column but it's not working.If I can get this to work I would like to add additional aureport options.

I retooled my other script (thanks to those who helped) to work for resizing images for a netbook with 1024x600. Thanks to the ImageMagick website for help with the syntax. Here's what worked for me:
Code:
#!/bin/bash
for SRCFILE in /home/robert/Pictures/*/*/*/*/*/*/*
do
RELPATH=`echo $SRCFILE | sed -e 's//home/robert/Pictures//'`
DESTDIR="/home/robert/tmp/portable/${RELPATH%/*}"

I figure anyone with a netbook is going to put a lower size/quality on their netbook and then keep the originals (music and pictures) on a different machine or an external hard drive.

View 9 Replies View Related(bare with me as I am sort of new with scripting) I am trying to figure out how to run a script that does a basic chkconfig and to get only those services that are running, but changing the color of "on" to red in my output file. Here is what I am working with so far:
Quote:
#/bin/bash
RED=$(tput setaf 1)
BLK=$(tput setaf 0)
[code]....
*I had to substitute a "-" and <colon_symbol> for ":" in front of the on's, because the forum thought they were smiley faces (i.e. n) how to make the "on" to be red while the rest of everything remains in black text. I have been trying to read up on sed and awk, but it is still pretty much a mystery to me right now. There will be other things in the output file that I wouldn't want a rogue "on" to be in red, so just the instances of "on" in that one chkconfig return.
am running Centos 5.4 and would like to write a small perl script to collect some info from mysql.
so I went
yum install perl-DBI
yum install perl-DBD-mysql
then
nano perl.pl

#!/bin/perl
use Mysql;

Why can't perl find Mysql.pm? I guess because it doesn't exist as I ran find / -name Mysql.pm, and also could not find it.
shouldn't that file have been created and thus exist after I install perl-DBD-mysql?
Code: cmd='date | wc'
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
