根据bash中的条件进行格式化 [英] Formatting based on condition in bash

问题描述

这是我的代码:

  grep -E -o "\b[a-zA-Z0-9.-]+@[a-zA-Z0-9.-]+\.[a-zA-Z0-9.-]+\b|first_name.{0,40}|[(]?[2-9]{1}[0-9]{2}[)-. ]?[2-9]{1}[0-9]{2}[-. ]?[0-9]{4}" file.txt | awk -v ORS= '
  NR>1 && !/,/ {print "\n"}
  {print}
  END {if (NR) print "\n"}' | sed -e :a -e '$!N;s/\n[0-9]{3}/,/;ta' -e 'P;D' | sed '$!N;s/\n\s*[0-9]//;P;D'

我很近.上面的代码有效，但是正在从电话号码中删除第一位数字.

I'm pretty close. The above code works, but is removing the first digit from phone number.

我正在寻找一种bash解决方案来执行以下操作:

I'm looking for a bash solution to do the following:

如果两行不以数字开头，则合并两行.如果该行以数字开头，则将前两行+该行与一行中3个字段的数字合并.

Combine two lines if the lines do not start with a number. If the line starts with a number, combine the previous two lines + the line with the number for 3 fields in one line.

这是一个例子吗?

    [e-mail]
    Jim Bob
    [e-mail]
    Jane Bob
    [e-mail]
    Joe Bob
    555 555 5555
    [e-mail]
    Jeff Bob
    ....

    Results:
    [e-mail] Jim Bob
    [e-mail] Jane Bob
    [e-mail] Joe Bob 555 555 5555
    [e-mail] Jeff Bob

谢谢！

推荐答案

使用awk

awk '/@/{if(s)print s;s=""}{s=(s?s OFS:"")$0}END{if(s)print s}' infile

输入:

Input:

$ cat infile
jim.bob3@emaawk '/@/{if(s)print s;s=""}{s=(s?s OFS:"")$0}END{if(s)print s}' infileil.com
Jim Bob
[e-mail]
Jane Bob
[e-mail]
Joe Bob
555 555 5555
[e-mail]
Jeff Bob

输出:

Output:

$ awk '/@/{if(s)print s;s=""}{s=(s?s OFS:"")$0}END{if(s)print s}' infile
[e-mail] Jim Bob
[e-mail] Jane Bob
[e-mail] Joe Bob 555 555 5555
[e-mail] Jeff Bob

说明:

Explanation:

 awk '/@/{                    # ir row/line/record contains @
           if(s)print s;      # if variable s was set before print it.
           s=""               # nullify or reset variable s
      }
      {
           s=(s?s OFS:"")$0   # concatenate variable s with its previous content if it was set before, with   
                              # OFS o/p field separator and 
                              # current row/line/record ($0), 
                              # otherwise s will be just current record

      }
      END{                    # end block
           if(s)print s       # if s was set before print it
      }
     ' infile
