Shell Programming and Scripting

Hi,

I have two problems in which i have stuck up.

a) To move the files and copy back.
b) To create user dynamically.

Question 1:

I have to move the files to some other directory and copy it when all the process is done.

I have the code like this:

Code:

$file = "/home/data/file1.txt";
$file1 = "/home/data/disk/";

system("mv $file $file1");

The problem here is i am able to move the files but again coping back is not happening. The entire directory is getting replaced.

How can i move the files from one directory to another and again copy it back to same directory?

Question 2:

I have to create a dummy user name dynamically how can i create dummy username dynamically. At present i am a root user.
How can i create dummy user name dynamically?

After creating dynamically i need to copy to this user created login and create the directory and move this file1.txt.

How can i do this in perl?

Regards

Why do you want to mv files from one dir to another and then again copy them back ? You could instead just copy them in the first place. Perhaps explaining what you're trying to do will help us help you better ?

Code:

$file = "/home/data/file1.txt";
$file1 = "/home/data/disk/";

$file is pointed to file, but $file1 is point to a folder.

Code:

$file = "/home/data/file1.txt";
$file1 = "/home/data/disk/file1.txt";
system("mv $file $file1");
system("mv $file1 $file");
