AWK在命令中包含空格

Question

我有字符串：“./ Delivery Note.doc 1”，其中：

$1 = ./Delivery
$2 = Note.doc
$3 = 1

我需要执行sum命令连接$ 1和$ 2但保留空格（./Delivery Note.doc）。我试试这个，但它修剪了空白：

| '{ command="sum -r "$1 $2" 

结果：./ DeliveryNote.doc

Answer 1

$ echo  "./Delivery Note.doc 1" | awk '{ command="sum -r "$1" "$2; print command}'
sum -r ./Delivery Note.doc

Answer 2

执行sum命令

echo  "./Delivery Note.doc 1" | awk '{ command="sum -r \""$1" "$2"\""; print command}' | bash
