dmesg isn't a standard output receival location or anything of that sort.
It just prints out what's in the kernel message buffer, so it contains
messages from the kernel or modules inserted.
standard output and error are both sent to your screen by default unless
you redirect it elsewhere. To redirect standard output:
command > stdout-file
to redirect error:
command 2> stderr-file
to have both stdout and stderr redirected to the same file you can copy
stderr to stdout like this:
command > stdout-file 2>&1
now stderr will be written to the stdout-file file
