[英]awk for string comparison with multiple delimiters
I have a file with multiple delimiters, I m looking to compare the value after the first /
when read from right left with another file.我有一个带有多个分隔符的文件,我希望将第一个/
之后的值与另一个文件进行比较。
code :-代码 :-
awk -F'[/|]' NR==FNR{a[$3]; next} ($1 in a )' file1 file2 > output
cat file1猫文件1
AAB/BBC/customer|fed|12931|

$ awk -F\| ' # just use one FS
NR==FNR {
a[$1]
next
}
{
n=split($1,t,/\//) # ... and use split to the 1st field
if(t[n] in a) # and compare the last split part
print
}' file2 file1
Output:输出:
AAB/BBC/customer|fed|12931|

If you use this [/|]
you will have 2 delimiters and you will not know what the value after the last pipe was.如果你使用这个[/|]
你将有 2 个分隔符,你将不知道最后一个管道之后的值是什么。
Reading your question, you want to compare the first value after the last slash without pipe chars.阅读您的问题,您想比较没有管道字符的最后一个斜杠之后的第一个值。
If there has to be a /
present in the string, you can set that as the field separator and check if there are at least 2 fields using NF > 1
如果字符串中必须有/
,您可以将其设置为字段分隔符并使用NF > 1
检查是否至少有 2 个字段
Then take the last field using $NF
, split on |
然后使用$NF
获取最后一个字段,拆分|
and check if the first part is present in one of the values of file2 which are stored in array a并检查第一部分是否存在于存储在数组a中的file2的一个值中
$cat file1

Example code示例代码
awk -F/ '
NR==FNR {a[$1];next}
NF > 1 {
split($NF, t, "|")
if(t[1] in a) print
}
' file2 file1
Output输出
