awk 将树中的三个模式转置为多行

Question

你好有没有人可以建议如何转置树视图中具有 3 种模式的多行

listb: harold newu/edu
  tag: 05.8s
    step: sha256asd6f4, size: 1024
    step: sha256asd6f5, size: 1024
  tag: 06.8s
    step: sha256asd6f8, size: 1024

listb: break version
  tag: 05.8s
    step: sha256asd6c5, size: 720

listb: version/test
  not exist

我需要对齐到以下输出

listb: harold newu/edu tag: 05.8s step: sha256asd6f4, size: 1024
listb: harold newu/edu tag: 05.8s step: sha256asd6f5, size: 1024
listb: harold newu/edu tag: 06.8s step: sha256asd6f8, size: 1024
listb: break version  tag: 05.8s step: sha256asd6c5, size: 720
listb: version/test not exist

我尝试了这个部分解决方案，但它缺少第三个匹配模式“步骤” awk 根据模式转置行并在之后移动（复制）剩余的列

Answer 1

感谢您编辑您的问题以展示您已经尝试过的内容（这使得提供潜在解决方案变得更加容易）；这是一种“更简单”的方法，基于每个“块”中是否存在“步骤”和“不存在”，并且只有两个缩进级别：

awk 'BEGIN{OFS=" "} /^[[:alpha:]]/ {a = $0} /^  / && !/^   / {gsub(/^ {1,}/, "", $0); b = $0} /^    / {gsub(/^ {1,}/, "", $0); c = $0} /step/ {print a, b, c} /not exist/ {print a, b}' file
listb: harold newu/edu tag: 05.8s step: sha256asd6f4, size: 1024
listb: harold newu/edu tag: 05.8s step: sha256asd6f5, size: 1024
listb: harold newu/edu tag: 06.8s step: sha256asd6f8, size: 1024
listb: break version tag: 05.8s step: sha256asd6c5, size: 720
listb: version/test not exist

---

更好的格式：

awk '
BEGIN {
    OFS = " "
}

/^[[:alpha:]]/ {
    a = $0
}

/^  / && ! /^   / {
    gsub(/^ {1,}/, "", $0)
    b = $0
}

/^    / {
    gsub(/^ {1,}/, "", $0)
    c = $0
}

/step/ {
    print a, b, c
}

/not exist/ {
    print a, b
}' file
listb: harold newu/edu tag: 05.8s step: sha256asd6f4, size: 1024
listb: harold newu/edu tag: 05.8s step: sha256asd6f5, size: 1024
listb: harold newu/edu tag: 06.8s step: sha256asd6f8, size: 1024
listb: break version tag: 05.8s step: sha256asd6c5, size: 720
listb: version/test not exist

$ cat tst.awk
match($0,/[^[:space:]].*/) {
    if ( RSTART > prevRstart )      { indent++ }
    else if ( RSTART < prevRstart ) { indent-- }

    val[indent] = substr($0,RSTART,RLENGTH)
    prevRstart  = RSTART

    if ( indent == 3 )      { print val[1], val[2], val[3] }
    else if ( /not exist/ ) { print val[1], val[2] }
    next
}
{ indent = prevRstart = 0 }

$ awk -f tst.awk file
listb: harold newu/edu tag: 05.8s step: sha256asd6f4, size: 1024
listb: harold newu/edu tag: 05.8s step: sha256asd6f5, size: 1024
listb: harold newu/edu tag: 06.8s step: sha256asd6f8, size: 1024
listb: break version tag: 05.8s step: sha256asd6c5, size: 720
listb: version/test not exist

Answer 3

awk '
   {gsub(/^ */,"")}
   /^listb/{list=$0; next}
   /^tag/{tag=$0; next}
   /^step/{print list,tag,$0}
   /^not exist/{print list,$0}
' file
