create a Cron file and script. I've tried reading through my Linux book but I am just lost here. I need to create a Cron file that will perform a Level 0 backup once per month, a Level 2 dump one day per week, and a Level 5 dump every day that neither a level 0 nor a level 2 dump is performed.
I want to create a shell script that I can run as a cron job to do automated backups. how to proceed. I have the source code and have pulled out the backup source files. Here is the link for the source code. The download is at the bottom of this page. The backup files can be found in the src folder listed as backup.cpp and backup.h [URL]
If someone can do this, I believe it will make a nice addition to the Basket application for all.
Also I am not running Kubuntu I am running Karmic 9.10 64 bit
error message when I ran my program that I couldn't open my local file. I have two files first one is called client, second one is called server I am using named pipes to sent a message from client to the other file called server in client I used mknod() to create the two named pipes,one for read,one for write and created new thread in client using fork() spawned a child process that executed the server file both named pipes are opened the client file got the message from the user and sent it through the named pipes to the server file when the server receives the message , it needs to verfify it is correct in the server file, a local file descriptor is created to read and send this verifing message when it is not correct but I am getting an OPEN() error when I tried to open this shared local array buff and attach it to a file descriptor where the message is kept why do I get this error in server file
int main() { /*both named pipes are open*/ rfd=open(IFIO1,0); wfd=open(IFIO2,1);
I am a windows user and am trying to display a jpg image file on linux every x hours.In Windows, if I were to perform the same task, I would just give out the path to schtasks.exe and it would open the image in the default viewer,is the case same with linux as well? Do I just execute:
crontab now + 1 hour abc.jpg ? The linux is OpenSuse or Debian I guess.
what is the use of placing any file in /etc/cron.d folder , is there any use of it ? will crond daemon run the files automatically which are placed in /etc/cron.d daemon ?
I am trying to have the files from /user/directory copy every hour to /backup/user/directory. It would seem that cron or crontab is what I need to use. Looking at previous posts and other documentation only shows how much I don't know. When I type crontab -e I get a blank file I can type into, seemingly using vi as the editor. I have no problem with that but when I type cron -l, I get my text after a message about "Do Not Edit this File". What I am reading just makes no sense, I am not understanding even the most fundamental aspects of cron or crontab. Where I can get the most basic of basic instructions to try to understand this function?
My cron job is executing the below mysqldump command but it produces an empty sql file. However, when I run from the command line, it works as expected.

I saw an article use the following cat command to create a new text file:$ cat > first.sh << ENDAnd then after press the 'return' buttion, a '>' sign appeared expecting you to input the content. If I type 'END' then the 'return' button, then a new text file is created with what I just typed...I'd like to know what's the differnece in just type:$ cat > first.shwithout the '<<' sign?What '<<' really means? I cannot find it's meaning anywere... seems it's not in the redirection section.

jump into a Linux class in college with only 3 weeks left in the course. I thought I would be able to catch on, and go figure, it didn't exactly happen that way. I was given an assignment to do, and I am so far lost it isn't even funny. I need to create a directory structure, set up file security, create a step by step instruction manual on how to copy/delete said files, and create a guide to common Linux commands. How would I create these files in root and share them with the other users? and where can I find a list of common commands and their functions?
I am trying to use ln to create a hard link to file a and whenever I do it, it creates a copy of the file instead. After having edited file a, when opening the link, it shows the old information and opening file a shows the new information. The command I am using is
Code:
ln /home/user/file
within the new directory i am trying to link from. I am using centos 5.4.
I want to put: xmodmap -e "pointer =3 2 1" somewhere in the startup. It seems creating an .xsession is the solution. But after I create a .xsession file in my home folder, the next time I run startx the screen just turns black. (And only for a short while can I switch to another virtual terminal, before that too becomes impossible). After deleting the file it runs OK again. I'm not using any login/desktop manager. I use IceWM on Debian Squeeze. Is there some script/import that has to be present in the .xsession file, or is something else going on? Also I'd like to know what I should do when I get a black screen. Turning off the PC is such a crude method
I just installed XMMS and I want to create a shortcut on the desktop to run it. I found a how-to video for creating shortcuts so I have the gist of it (I was able to create one for Firefox) but I don't know where to find the executable file for XMMS to do the same. I just don't know enough about Linux's file structure to know where to look.

I can do:mkdir messages and then: touch messages/hello.txt Is there a command that will do both - create the directory if it doesn't exist, and then the empty file? Something like: touch -p messages/hello.txt
I am trying to create an empty file based on the remaining hard disk space. The problem is that when I create a file that is 1 GB large, the df command shows the remaining space to be only 12 kb smaller than it was before the file was created.
