Question

假设我有3个变量，每个变量都有一个多行输出，如下所示：

IPs="10.0.0.1
10.0.0.2
10.0.0.3
10.0.0.4"

MACs="08:16:E9:3D:12:D5
C6:70:A5:25:FF:58
42:96:ED:C8:D5:80
05:89:C6:37:68:9B"

Vendors="Apple
Intel
Sagemcom
HP"

我希望将它们放在一起，就像这样：

10.0.0.1 08:16:E9:3D:12:D5 Apple
10.0.0.2 C6:70:A5:25:FF:58 Intel
10.0.0.3 42:96:ED:C8:D5:80 Sagemcom
10.0.0.4 05:89:C6:37:68:9B HP

我该怎么做？

Answer 1

使用粘贴和bash：

paste -d " " <(echo "$IPs") <(echo "$MACs") <(echo "$Vendors")

10.0.0.1 08:16:E9:3D:12:D5 Apple
10.0.0.2 C6:70:A5:25:FF:58 Intel
10.0.0.3 42:96:ED:C8:D5:80 Sagemcom
10.0.0.4 05:89:C6:37:68:9B HP

Answer 2

我们在macOS（BSD）上也是：

rs 3 <<<"$IPs $MACs $Vendors" | rs -C' ' -T

10.0.0.1 08:16:E9:3D:12:D5 Apple 
10.0.0.2 C6:70:A5:25:FF:58 Intel 
10.0.0.3 42:96:ED:C8:D5:80 Sagemcom 
10.0.0.4 05:89:C6:37:68:9B HP

将两个（或多个）多行变量放在彼此旁边bash
