How do I remove the error output when running a command?

Question

For example, the command:

$ grep -lr "sample" .

In addition to printing files that contain the string "sample", it outputs errors that clutter the output.

grep:<...>: No such file or directory
grep: <...>: No such file or directory

You can use the built-in command options (according to the help):

$ grep -lsr "sample" .

And you can redirect the error output to nowhere:

$ grep -lr "sample" . 2>/dev/null
