hi,i am using ubuntu and generally use VI editor to write shell scripts. i am required to write a shell script to copy the text of one file(a text file) into another file.While the script executes, the shell shall ask the user to input the source filename and destination filename (both these files have been initially created by using "cat" command in the terminal).

Hi group,
I am very beginner in shell scripting and self learning.
I am trying to create and executable script to run awk from user defined variables.

Hi all,

I have a server running Ubuntu 10, it mostly has PHP websites with MySQL databases.
I need to write a backup script
to backup the database
to zip up all the php files.
Is it better security to do write my backup script in PHP or shell? Or does it not matter?
I like PHP more, because that lets me have the database password in only one place, a PHP file.
