And much better will be:

 
[[ -f src_file ]] && cp src_file dest_file 2>/dev/null

So with above code, even if you don't have the source file, the script won't call cp command unnecessary. Also, it gives you flexibility to trap the information about missing file as well if you call in nested if - else statement
