Awk有条件的，如果有的话

我有一个文件，它不想弄乱序列，所以我正试图计算出我的awk条件语句

如果$3有TBstring，请删除它并将其乘以1024，如果它有GB，请删除它删除字符串GB而不执行任何操作

试一试：

awk '{s=($3=="TB")?"-":$3=$3*1024; print}';awk '{s=($3=="GB")?"-":'s/GB//g'; print}' file

---

请您尝试以下，书面和测试显示的样品

awk '
$3~/[tT][bB]$/{
  temp=substr($3,1,length($3)-2)
  $3=temp*1024
}
$3~/[gG][bB]/{
  $3=substr($3,1,length($3)-2)
}
1
' Input_file |column -t

说明：增加对以上内容的详细说明

awk '                                   ##Starting awk program from here.
$3~/[tT][bB]$/{                         ##Checking condition if 3rd field is equal to tT OR bB then do following.
  temp=substr($3,1,length($3)-2)        ##Creating variable temp  which has sub-string from 3rd field.
  $3=temp*1024                          ##Re-creating 3rd field which has value of temp variable and multiplying it with 1024 here.
}
$3~/[gG][bB]/{                          ##Checking condition if 3rd field is having gG OR bB then do following.
  $3=substr($3,1,length($3)-2)          ##Re-creating 3rd field which has value of 3rd field apart from last 2 char of it.
}
1                                       ##Printing current line here.
' Input_file | column -t                 ##Putting output of awk program to column command to beautify it.

上述命令有效。awk从字符串的起始部分自动将字符串转换为数字。这里它忽略GB和TB部分

如果您关心小数点后有2位精度，即使它们只是零，您也无法使用

awk '$3 ~ /TB$/ { $3 *= 1024 }; $3 ~ /GB$/ { $3 += 0 };  {$3 = sprintf("%.2f", $3) } 1'

---

由于这是固定宽度的数据，使用GNU awk，您可以写入：

呆呆的 开始{FIELDWIDTHS=241911*；OFS=} {$3=sprintf%-11.2f，$3*$3~/TB/？1000:1} 1. "档案" 产出：

awk'$3~/TB$/{$3=$3*1024}$3~/GB$/{$3=$3+0}；{$3=sprintf%.2f，$3}1'这会破坏文件的序列。保留TB的行只会被转换。我理解这里的“序列”是指行的顺序。此命令中保留了行的顺序。在第二个命令中，只需要对行进行不必要的修改，这些修改可能会被忽略。答案的第二部分只有在小数点后的尾随零丢失是个问题时才有用。快速问题。如果我想在这里包含浮点值，我应该编辑哪一个？@gafm，你可以使用$3=sprintf%.04f，temp*1024，它将有浮点到4个点，如果这里有任何问题，请让我知道。太好了，@RavinderSingh13，这是否也会保留例如$1有一个带空格的数据？@gafm，空格部分已经处理好了，通过使用列，它美化了输出中的空间。一如既往地感谢您的帮助。请你也看看这个好吗
