I'm trying to define a variable, CHAN, by dividing another variable, FREQ, by a number. FREQ is a value from a file (called header.txt). What I think I'm doing with this bit of code is reading a number from header.txt whose location is specified by the head and tails, assigning it to FREQ and then defining CHAN with bc.
Code:
#!/bin/bash
while read FREQ

Kindly take a look at the code below :
Code:
#include <stdio.h>
struct test
{
int i;
int j;
[Code]....
why i am getting this error. I know the error is occuring because i have assigned values to obj.i and obj.j outside main(). But i want to know why do that result in an error. From my part i have created an object 'obj' of stucture 'test' and assigned values to its variables.
Since I got the liquorix kernel installed on my machine I got an error of setting kernel variable error. net.ipv6.bindv6only at boot time, since it wasnt a big deal I never looked further into it, but now that I had some spare time and I didnt want to see any errors on my machine I found a solution for it, with a little googling all we need to do is read the /usr/share/doc/procps/README.Debian and bingo no more error i hope this help anyone else with the same problem. I did the 3rd suggestion on that file to load the module in /etc/modules cheers.

I am trying to think of a logic where my file contains some data I had to read and do some processing. Issue is that file contains data multiple times. For example:
:::::::::::
var1=value1
var2=value2
[code].....
I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.

I'm having a strange issue with the PATH variable when running the command 'sudo su'. When executing this command the PATH variable changes. No problems there, but it changes to:

Looking at this, there are two weird entries (//sbin and //bin) which should both start '/usr' instead. I'm not sure how I've managed to change this, or how a piece of software I'm using has done it (more likely it was me I expect), but could anyone suggest which file to look in to correct it? If it makes a difference the machine is running CentOS 5.

I have problems with setting my JAVA_HOME variable. I am using Slackware 12.0, bash shell. This is a question for the 'Linux Newbie' forum (not slackware-specific).
I have set JAVA_HOME in my /etc/profile, like this:
But when I login in with my user name and type env on the command line, I get for JAVA_HOME the following:
Also, in my /etc/profile I have put the path to my java in the PATH variable, like this:
And when I type env when I login, then the PATH variable contains correctly the path to the jdk (as I have put it into /etc/profile).
I expect that after I have set everything as I want in /etc/profile, and restart the computer then what I have set will be relevant and when I login and type env, I will get values to the variables equal to those I have set in /etc/profile. Why it does not happen?
I have particularly a problem with a Java application, which I want to run. When I type ant, I get:
error: JAVA_HOME is not defined correctly. We cannot execute /usr/lib/java/bin/java.
how can i set variable by following Quote: >> ./kuku -u a b c d -n ga go gi how can i set variable at tcshell... Quote: user = a b c d num = ga go gi

I have been trying to change my PATH environment variable to no avail. I am using Jessie i386 with MATE. Using my .bashrc file works but not well because with subshells the modifications get repeated. I want the change to occur on login.
I tried modifying ~/.profile ~/.bash_profile /etc/profile and /etc/environment and one or two others but in no case did my change get picked up even after logging out and in again and even after rebooting. I searched the Internet and found each of the above places to make the change but they don't seem to work with Jessie.
Where do I make the necessary change?
I am connected to work via a VPN. I am logging into a Solaris box at work from OpenSuse 11, using ssh -X. I would like to start a GUI on the solaris box. The problem is that I don't know what value to give the DISPLAY variable. Is it the local internal LAN ip address, for my machine? I did try that, and I tested it using, xterm on the solaris machine. It says it can't open the display. I have enabled remote connections on my machine using xhost +.I have to run a performance test on the Solaris box at 7am in the morning... so need to find out how to start the GUI
View 6 Replies View RelatedI've been using Kate for a while without any problems.
However, today I tried to install Kedit.
Then I got this message:
"There was an error setting up inter-process communications for KDE. The message returned by the system was:
Could not read network connection list. /home/mikeb/.DCOPserver_XXX__0
Please check that the "dcopserver" program is running!"
Then I uninstalled Kedit, hoping that the damage would be undone.
However, Kate still shows the same message upon startup.
So I reinstalled Kate, and got the same thing.
What did the Kedit installation mess up, and how I can I fix it so I can use Kate again?

I have created a shell script to customise mv command, now i have achieved to accomplish all the functionality of mv by using alias. But i found difficulty in accomplish the funcionality with options [Like mv -i or mv -f etc.]. I thought about logic which check the first argument whether its starting with a minus [-] or not. if its starting with argument it will set a flag and execute accordingly. But whenever this condition is checked it shell script will throw error of destination operand missing. But the same will work with out option.
Note: I have used an minus[-] expression for decreasing a counter on the script above. The below mentioned is the portion of script. Sry for troubling Im not gud @scripting.

{
argument=`expr $argument - 1`

I am a newbie to Linux. I tried setting environment variable using export JAVA_HOME=/usr/java/jdk1.6 but that was not permanent (i.e is was there for that terminal session). I want to know how can i set environment variable permanently in Fedora 13 just like we do in windows.After google search, some user suggested to edit bashrc and profile file for setting environment variables but above file contains some shell programs.
