[Help-bash] Best way to suppress the error message in $(< nonexistent_fi

Hi,

I only find the exec way to suppress the error message of $(<
nonexistent_file). But the syntax doesn't look very nice. Is there a
better way to do so? Thanks.

x=$(< nonexistent_file) 2> /dev/null # This doesn't work.

exec 3>&2 2>&- # This works
x=$(< nonexistent_file)
exec 2>&3 3>&-

Peng
