I'm trying to use system to call echo and pass variables to it. That was a success. The problem is the variables inside the while-loop i wrote cannot be manipulated. what I'm doing wrong here? here's the code:
Code:
#include <iostream>
#include <stdlib.h>
#include <string>
#include <sstream>

I have to run "pppd call idea" command from root shell every time to connect to internet from mobile. Now I want a script so that I just run it to connect. Something like :
#!/bin/sh
echo "password" --stdin | su -
pppd call idea
But its showing error that "standard in must be a tty". Why is this. Using CentOS 5.5
I have a router with linux firmware and attached to it a USB modem with which I can do both data and voice.Any other command send through echo method works ok. I was able to send SMS, edit phonebook and many many other stuff, but not make a call.So what is different from sending the call command within Minicom 2.5 and echo it?

In practice I have a script that call a java program that call a linux system command. The script if I run it, from a shell functions well,so it is not a java problem. The problem come out when i put this script in a crontab schedulation. The result in this case is that java do not execute the system command. I think it depends on crontab

When I run ./configure for ettercap, it tells me I need to install GTK, Pango, or ATK. But, I've installed them all with yum, and the -devel versions of them too. For example I did "yum install gtk+" and "yum install gtk+-devel" for GTK, Pango, and ATK.
But even though I installed all these dependencies, I'm still getting this error. I'm thinking the problem is that it's looking for gtk, atk, or pango in the wrong place. A copy of the relevant error section produced by running ./configure is below:

Alternatively you may set the GTK_CFLAGS and GTK_LIBS environment variables to avoid the need to call pkg-config. See the pkg-config man page for

I have to linux boxes (ubuntu 10 and ubuntu 9), both are in the same network - i can do ping between them- so, I need to pass several files between them and i want to do it using the network, i went to nautilus and then smb://192.168.0.1 but i couldn't connect.

Doing these commands for multiple command line file inputs is the goal. So I can just type ./script.sh *.mkv in my terminal.This is what I have so far, but it doesn't work whatsoever.

I have a process that forks, where the childs puts some data of random size and exits while the parent should get the data and does some manipulation.. here I have used a pipe for child to write the data and parent to read the data.. Child simply dumps the data, and the data is of any size even child and parent doesnt know.
I have used select in the parent to see whether there is any data coming on the reading end of the pipe.. if there is a data.. I copy into a buffer.. Im reading the data continusly when the child exits after closing the writing end of pipe. Parent gets blocked on the read part But my question is how parent know the other of pipe is closed when using the select call. In otherwords.. while using select in readfds, how would i know the other end has closed the pipe..

I cannot find the syscall_table.S or entry.S file in the source code , so i didn't made the entry of the syscall in this file, how much necessary the entry of syscall presence in this list and how to get this file?
I am searching for any system call similar to "ls" command we use in shell. My requirement is knowing the files and directories in curent working directory and process them based on there type. Here as of now I spawn another procees with system command like system
("sh ls -l | grep ^d | awk '{print $9}'").
Instead of this I want to use any system command where I can capture this information directly into my local character buffer. My opinion is that system calls will not spawn another process as a result less time it takes, another reason is once I use the system command again I need to capture the information to a local file then again read it into local buffer. I want to avoid the file manipulation here.
I am trying to ptrace a process and when the system call is 'cd' change directory,
the ptrace process is able to trap it by comparing it against "__NR__open" system call. When I try to read the name of the directory from ebx register using peek_data I am getting ".message" and not the directory name.
The same thing works fine when I am tracing a file open system call.
