What is the difference between "exec 5 > myfile" and "exec 2 > myfile"?

Hi,

I know here is not forum for shell script. But I hope there is someone could answer my question.

exec 5 > myfile redirects file descriptor 5 to myfile so any subsequent writes to fd 5 go to myfile.

exec 2 > myfile is the equivalent for file descriptor 2 which is normally stderr.
