bash - 将多个命令输出到列中

Question

我正在尝试编写一个脚本来运行各种命令并将每个命令的结果输出到一列中，但我无法让输出显示在列中。

#!/bin/bash

# Get GBP Neighbour NAMES
NEIGHBOR=$(vtysh -c 'show ip bgp neighbors' | grep Incoming | awk '{print $7}')

# Get IPs of BGP neighbours
IP=$(vtysh -c 'show ip bgp summary' | awk '{print $1}' | head -n -2 | tail -n +6)

# Get Up/Down time
TIME=$(vtysh -c 'show ip bgp summary' | awk '{print $9}' | head -n -2 | tail -n +6)

# Get State/PfxRcd
STATE=$(vtysh -c 'show ip bgp summary' | awk '{print $10}' | head -n -2 | tail -n +6)

如何让输出按列分隔，例如:

NEIGHBOR | IP | TIME | STATE

Answer 1

使用粘贴命令:

paste -d'|' <(echo "$NEIGHBOR ") <(echo "$IP") <(echo "$TIME") <(echo "$STATE")
