How to avoid error-message during the execution of a bash script?

Question

I need to write a bash-script which will find all files with name string.h on the computer and copy them to some folder. My code is here:

#!/bin/bash

sudo find / -type f -name "string.h" -exec cp {} $HOME/MyDocuments \;

But during the execution of the script, I get error-messages on my console terminal "permission denied". How I can avoid getting this message? Console terminal must be clear.

Suppress the error messages from stderr(2) to the NULL stream designated by /dev/null

sudo find / -type f -name "string.h" -exec cp "{}" $HOME/MyDocuments \; 2 > /dev/null

where the 2 in the above line stands for file descriptor.

I would personally recommend you to investigate the actual cause of the issue rather than suppressing it. Do the above only if you are absolutely sure that the errors are trivial.
