remove a "bad address" error from the standard output on the linux terminal

Question

when attempting to copy a file inside a mounted directory, I got this message printed on my terminal:

cp: writing `file': Bad address

However, the copying operation is successfully executed, but I just want to delete this message (for a presentation purpose). any idea how to remove this warning (or error) ?

Answer 1

You could redirect errors to /dev/null or to a log file, like this :

cp a b 2>/dev/null

or

cp a b 2>errors.log
