@ colucix--

great, thanks, I never even thought of that.

For comparison sake, here's what I get on my system:

Code:
bash-3.1# type cp
cp is /bin/cp
bash-3.1

ok tried that-
cp is aliased to 'cp -i'
what does that mean?

my script is running good now, im getting the output from what comes up in my screen using
Code:
yes| cp -LRuvpf /dir/filename /mnt/usbdrive/filename >/usbdrive/error.log 2>&1
what does "2&1" actually mean?

what i want to do is have a file after my script runs to show me the succesful completion and errors from each command. using the above command creates a file with all output from the command being executed

thanks for all the help

Without the -i option, and without the --reply option, but WITH the -f option, it should not be asking you *anything* -- it should just DO it..

i have tryt that and it does work you can use that simple way

what does that mean?
It means that: in your bash_profile or /etc/profile config file (or possible even by a symlink somewhere) an ALIAS is configured. An ALIAS is a way of creating a command, in a sense. Have a look at your shell's MAN PAGE to read about aliases.

what does "2&1" actually mean?
There are two 'channels' of output of text, from a program; stdout, and stderr. stdout is the "standard output" where normal output shows up. stderr is "standard error" where errors are generated.
stdout is signified by &1, and stderr is signified by &2. By saying 2>&1, we are telling the shell to redirect stderr into stdout.

Again, your shell's MAN PAGE explains shell redirection.

Not sure I follow the last part there, but try using `cat` and pipe it into `less` to view the log file after the copying is done:

shell# cat logfile | less
