Проверка на численное значение вида [0-9]* не очень хороша тем, что
3foo подходит под эту проверку, но при этом не является числом.

В /usr/bin/hsh-sh-functions есть специальная функция, используемая
для проверки численного значения ключа:

opt_check_number()
{
	[ -z "$(printf %s "$2" |tr -d '[0-9]')" ] &&
		[ "$2" -gt 0 ] 2>/dev/null ||
		Fatal "$1: $2: invalid number."
	printf %s "$2"
}

По аналогии get_veid можно переписать так:

get_veid()
{
	local name="$1"; shift
	[ -n "$name" ] || return 1
	if [ -z "$(printf %s "$name" |tr -d '[0-9]')" ] &&
	   [ "$name" -gt 0 ] 2>/dev/null; then
		echo "$name"
	else
		vzlist -aH -oveid,name |
			awk "-vname=$name" '$2==name{print $1;exit}'
	fi
}
