Linux 如何使 awk 输出更具可读性

发布于05月15日

有了这个代码，我得到了值最高和最低的学生.

但我找不到如何将其转换为更具可读性的输出.

代码

awk -F ';' 'NR==1 { min = max = $2; mina = maxa = $1 " " $2; next }
$2==max { maxa = maxa ", " $1 " " $2 }
$2==min { mina = mina ", " $1 " " $2 }
$2>max { max = $2; maxa = $1 " " $2 }
$2<min { min = $2; mina = $1 " " $2 }
END { print "Max:", maxa
  print "Min:", mina }' 备注.txt备注.txt

`备注.txt备注.txt`

pepe;5
marcos;7
marta;70
luis;70
ana;5
pedro;9
paco;70
pepa;7
rosa;5
manu;8

电流输出

Max: marta 70, luis 70, paco 70
Min: pepe 5, ana 5, rosa 5

期望输出

Max: 70 [marta,luis,paco]
Min:  5 [pepe,ana,rosa]

我怎样才能达到这样的yields 呢？

推荐答案

所需的更改真的很小.在寻求帮助之前，你可能会试着自己解决问题.

awk -F ';' 'NR==1 { min = max = $2; mina = maxa = $1; next }
  { val = "," $1 }
  $2==max { maxa = maxa val }
  $2==min { mina = mina val }
  $2>max { max = $2; maxa = $1 }
  $2<min { min = $2; mina = $1 }
  END { printf "Max: %2i [%s]\n", max, maxa
    printf "Min: %2i [%s]\n", min, mina }' notas.txt

格式说明符%2i预计最大值为两位数；如果它可以上升到三位数，则可能在两个位置都使用%3i.
