删除包含卡片详细信息的记录。这可以出现在摘要列的任何位置。

要检查的条件是：

电话号码是10位数，因此不能删除。
要删除的连续数字超过10位
需要删除中间空格或连字符或其他特殊字符的连续数字超过10位数。

我尝试了这个逻辑：

首先将数字分组为

sed 's/\([0-9]\) \([0-9]\)/\1\2/g' input_file - 删除数字中的空格
sed 's/\([0-9]\)-\([0-9]\)/\1\2/g' input_file - 删除数字之间的连字符

结果：已达到

SNO|PRODUCT|SUMMARY              | ADDRESS|DATE|     
101|111111|This cutomer is good|Adress1|01/01/2012|

101|111111|This cutomer is credit number 1245235544521214152|Adress1|01/01/2012|

现在我需要删除数字大于9,99,99,99,999的行，以便只删除带有卡号的行。

无法执行大于“摘要”列中的检查。

对此有任何帮助吗？

Answer 1

我建议使用awk而不是sed，因为它可以更容易地将过程分成几个步骤。这是一个产生所需输出的awk脚本：

# set field separator to |
BEGIN { FS = "|" }

{
    # save third field
    summary = $3
    # remove everything not a digit from the start
    sub(/^[^0-9]+/, "", summary)
    # remove hyphens and spaces from what is left
    gsub(/[- ]/, "", summary)
    # print the whole record unless the number is too long
    if (length(summary) <= 10) print;
}

测试出来：

$ cat file
SNO|PRODUCT|SUMMARY              | ADDRESS|DATE|  
101|111111|This cutomer is good|Adress1|01/01/2012|
101|111111|This cutomer contact is 223 456 7777|Adress1|01/01/2012|
101|111111|This cutomer is details 4450 2214 2254 2133|Adress1|01/01/2012|
101|111111|This cutomer is phone number is 223 124 4411|Adress1|01/01/2012|

101|111111|This cutomer is credit number 1245 2355 4452 1214 152|Adress1|01/01/2012|
$ awk -f script.awk file
SNO|PRODUCT|SUMMARY              | ADDRESS|DATE|  
101|111111|This cutomer is good|Adress1|01/01/2012|
101|111111|This cutomer contact is 223 456 7777|Adress1|01/01/2012|
101|111111|This cutomer is phone number is 223 124 4411|Adress1|01/01/2012|

顺便说一下，它是客户，而不是cutomer：）

$ cat tst.awk
BEGIN { FS="|" }
{
    maxLgth = 0
    tail = $0
    while ( match(tail,/[0-9]([0-9]|[^[:alpha:]])+[0-9]/) ) {
        cur = substr(tail,RSTART,RLENGTH)
        gsub(/[^0-9]/,"",cur)
        curLgth = length(cur)
        maxLgth = (curLgth > maxLgth ? curLgth : maxLgth)
        tail = substr(tail,RSTART+RLENGTH)
    }
}
maxLgth > 10

$ awk -f tst.awk file

不清楚你的意思是什么＆＃34;特殊字符＆＃34;所以我假设上面你的意思是非字母字符。

仅删除包含卡片详细信息的行
