如何针对不同的字段使用不同的颜色打印 awk 的结果？

Question

 ads2 cls create | awk -F [\"] '/^>>> cluster established .../ { strt=1 } strt!=1 { next } $1 ~ "name" { cnt++;nam[cnt]=$2 } $1 ~ "state" {stat[cnt]=$2;print -e "Node "nam[cnt]" has state "$2 } END { if (stat[1]=="3" && stat[2]=="3") { print "Cluster established. Starting session manager" } else { print "Failed" } } 

上述命令给出了输出ads2 cls create，awk检查特定的输出变量，并根据该输出返回"Cluster established. Starting session manager"或Failed

但是，我尝试为green第一个输出着色，为第二个输出着色。我在互联网上搜索，没有找到任何与使用print命令打印的彩色文本相关的内容，而是使用echo -e命令。

那么，我怎样才能使用当前的实现来为这两个输出着色！

命令的输出ads2 cls create如下所示

kernel with pid 3336 (port 9011) killed

                address = "http://xx.xx.xx.xx:9011/";
                state = "3";
            }
            node {
                name = "xxx-NB-0144";
                address = "http://xx.xx.0.xx:9011/";
                state = "3";
            }
        }

Answer 1

您可以在 awk printf 命令中使用 ANSI 颜色序列，如下所示：

awk 'BEGIN{printf "\x1b[32m%s\x1b[0m\n", "Succeeded"}'

awk 'BEGIN{printf "\x1b[31m%s\x1b[0m\n", "Failed"}'

前任：

要将其应用于您的情况，请将END块修改为：

  END { 
    if (stat[1]=="3" && stat[2]=="3") { 
      printf "\x1b[32mCluster established. Starting session manager\x1b[0m\n" } 
    else { 
      printf "\x1b[31mFailed\x1b[0m\n" 
    } 
  }
