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

LuckyBackup has a feature to allow issuing commands before it does the backup. I have been investigating scripts (I have never written one.), but do not understand how to use them to this end.

View 6 Replies View RelatedSometimes when I try to open some chat application i get a strange warning message asking for password. The message is that /usr/libexec/mission-control is trying to gain access of the system, please provide the password. On top of the message box it shows "Unlock Keyring".
This very weird, as I am also unable to do a print-screen when this message box is up.
what this message is all about and what does the executable /usr/libexec/mission-control do?

Why is it when I run gedit, there are always tonnes of error or warning messages? (Even though my gedit ran successfully)
To name a few:
1. GConf error: failed to contact configuration server; some possible causes are that you ned to enable TCP/IP networking for 0 RBit, or you have stale NFS lockes due to a system crash.
2. Failed to get connection to session: Did not receive a reply among others.
Just to mention again my gedit is running fine though. Is there any configuration that I missed out? or I can disable to avoid these nuisance?

View 3 Replies View RelatedI recently did a clean install of Maverick Meerkat and copied a few configuration files from my old system. I can log on normally, and the system works just fine. However, when I lock the workstation with any method, the system will not accept my password. I'm certain that I'm typing it correctly (I tried over 20 times) and that the capslock is not on. When I reboot, I can log in again just fine. In other words, my password only works at initial login, not when unlocking the workstation.

My ubuntu version is 9.10
I was working on adding a call system to my linux kernel.
I tried a lot of threads and .pdf files which explaining how to add a system call. Like :
1- This thread
2- .pdf file
and many ..
I tried working with linux-2.6.18.1 , 2.6.33.1 , 2.6.28.1 and many many.
But , all of them are returning -1 as result ..
I prefer working on 2.6.28 kernel version or above like 2.6.33.1
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..
mplement the read system call in unix...i want the code for read system call...

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.
I am trying to figure out how i would go about finding out where system call is made and error checking is not done. I have code below, if somebody can point me in the right direction where system call is made but error checking is not done.Quote:
#include "shell.h"
#include <stdio.h>
#include <string.h>
