linux - 重新格式化输出

Question

我正在使用以下命令获取磁盘状态:

/opt/Navisphere/bin/naviseccli -h VNX5500-1-1 getdisk -state

我得到的输出是这样的:

Bus 0 Enclosure 0  Disk 0

State:                   Enabled
Bus 0 Enclosure 0  Disk 2

State:                   Enabled
Bus 0 Enclosure 0  Disk 4

State:                   Enabled
Bus 0 Enclosure 0  Disk 6

State:                   Enabled
Bus 0 Enclosure 0  Disk 8

State:                   Enabled
Bus 0 Enclosure 0  Disk 10

State:                   Enabled
Bus 0 Enclosure 0  Disk 12

State:                   Enabled
Bus 0 Enclosure 0  Disk 14

State:                   Enabled
Bus 0 Enclosure 0  Disk 16

我正在尝试格式化输出以便为每条总线获取一条线。像这样的东西:

Bus 0 Enclosure 0  Disk 0   [State: Enabled]
Bus 0 Enclosure 0  Disk 2   [State: Enabled]
..

使用awk:

awk '/^Bus/ {a=$0}; /^State/ {print a" ["$1, $2"]"}' file.txt 

• /^Bus/{a=$0}:如果行以Bus开头，将行/记录保存为变量a

• /^State/{print a"["$1, $2"]"}:如果行以State开头，保存打印字段带有 a 的所需格式

示例:

% cat file.txt
Bus 0 Enclosure 0  Disk 0

State:                   Enabled
Bus 0 Enclosure 0  Disk 2

State:                   Enabled
Bus 0 Enclosure 0  Disk 4

State:                   Enabled
Bus 0 Enclosure 0  Disk 6

State:                   Enabled
Bus 0 Enclosure 0  Disk 8

State:                   Enabled
Bus 0 Enclosure 0  Disk 10

State:                   Enabled
Bus 0 Enclosure 0  Disk 12

State:                   Enabled
Bus 0 Enclosure 0  Disk 14

State:                   Enabled
Bus 0 Enclosure 0  Disk 16


% awk '/^Bus/ {a=$0}; /^State/ {print a" ["$1, $2"]"}' file.txt 
Bus 0 Enclosure 0  Disk 0 [State: Enabled]
Bus 0 Enclosure 0  Disk 2 [State: Enabled]
Bus 0 Enclosure 0  Disk 4 [State: Enabled]
Bus 0 Enclosure 0  Disk 6 [State: Enabled]
Bus 0 Enclosure 0  Disk 8 [State: Enabled]
Bus 0 Enclosure 0  Disk 10 [State: Enabled]
Bus 0 Enclosure 0  Disk 12 [State: Enabled]
Bus 0 Enclosure 0  Disk 14 [State: Enabled]
