从输出bash更改特定行的颜色

Question

我有这个输出来自一个驱动器diag命令。

我只想对每个驱动器的3,4,5,7,9和12行在":“标志之后进行修改。这些结果是标准，但我想添加一些颜色，如果它说的是不同的。例如：

Slot Number        : 7   
Drive's position   : DiskGroup 1  
Media Error        : 4  (I want the whole line in red)
Other Error        : 3  (I want the whole line in red)
Predictive Failure : 1  (I want the whole line in red)
Raw Size           : 1.090 TB [0x8bba0cb0 Sectors]
Firmware state     : Failed. (I want the whole line in red)
Inquiry Data       : SEAGATE ST1200MM0099 ST31WFK0SZ2L 
Foreign State      : Unconfigured  (I want the whole line in red)
Media Type         : Hard Disk Device 
Temperature        : 22C (71.60 F) 
S.M.A.R.T alert    : Yes  (I want the whole line in red)

我想对每一个驱动器做那些改变，驱动器的数量是可变的，有时是多的，有时是少的。

我已经试过了，但没有用。

awk -F ':' '$1~/^(Media Error|Other Error|Predictive Failure)$/ && $2 > 0 {print "\033[31m" $0 "\e[0m"; next} 1'

Answer 1

使用任何awk：

$ awk -F '[[:space:]]*:[[:space:]]*' '
    BEGIN {
        tag2val["Media Error"]          = 0
        tag2val["Other Error"]          = 0
        tag2val["Predictive Failure"]   = 0
        tag2val["Firmware state"]       = "Online, Spun Up"
        tag2val["Foreign State"]        = "None"
        tag2val["S.M.A.R.T alert"]      = "No"
    }
    {
        tag = $1
        val = $2
        sub(/^[[:space:]]+/,"",tag)
        sub(/[[:space:]]+$/,"",val)
    }
    (tag in tag2val) && (val != tag2val[tag]) {
        $0 = "\033[31m" $0 "\033[0m"
    }
    { print }
' file

您只需在:周围包含空格，所以$2中的第一件事不是空白，而是从行尾去掉任何尾随空格(如您在输入中的空格)。我还整理了您的结束颜色转义序列，并设置$0，而不是打印在那里，所以你不需要一个next和输出来自两个不同的地方。
