Question

我有.csv文件，哪些字段用逗号分隔，行由\ n分隔。在某些行中，我有兆字节符号。我想用零替换它以（或多或少）正确的大小（以字节为单位）。

我拥有的是

，2.6 M，

我想要

下，2600000，

Answer 1

由于样本数据中的最后一行缺少一列，这很复杂。

awk 'BEGIN {FS=OFS=","} {$(NF-1)=$(NF-1)*1000000} 1' file

如果有时你有＆＃34; M＆＃34;有时＆＃34; K＆＃34;，我们可以容纳：

awk '
    BEGIN {
      FS=OFS=","
      mult[""]=1
      mult["K"]=1000
      mult["M"]=1000000
      mult["G"]=1000000000
    } 
    {
      split($(NF-1), a, " ")
      $(NF-1) = a[1] * mult[a[2]]
      print
    }
'

Answer 2

sed 's/\([0-9]*\)\.\([0-9]*\) M/\1\200000/' file

Answer 3

sed 's/ \([KMG]\)/000000000\1/
     s/\.\([0-9]\{3\}[0-9]*K/\1/
     s/\.\([0-9]\{6\}[0-9]*M/\1/
     s/\.\([0-9]\{9\}[0-9]*G/\1/
    ' YourFile

基于您的样本，其中只有1个字母的数字，我们应该更改1000个单位的倍数

可以使用sed 's/\.\([^,]*\) M/\1000000/' YourFile进行简化，如果只有M出现在您的样本中（1位数字仅在使用M的值后点）

sed / awk：用字节替换兆字节（插入零）
