the above coding works, but

$output=exec("cp file1 file2");
echo "<pre>$output</pre>";

does not works. can any one help me out of this problem

When I was executing the "cp" command it doesn't return anything. But it returned the name of the last file when i executed the "ls" command

try it on the command line ..

`cp file1 file2` doesn't return anything - so your script probably is working as it correctly returns nothing.

if you want to see output try

`cp -v file1 file2`
