Question

我需要比较file1，fileS中的字段5和字段，文件中的字段并在没有匹配时打印出来：

file A
ZEROC_ZAR,MKT,M,ZAR,3YEAR,7.59
ZEROC_AED,MKT,M,ZAR,4YEAR,7.84
ZEROC_ZAR,MKT,M,ZAR,5YEAR,8.03
ZEROC_AED,MKT,M,ZAR,7YEAR,8.33


file B
TKS,010690226,02977,AED,ZEROC_AED,3YEAR
TKS,010690231,02977,AED,ZEROC_AED,4YEAR
TKS,010690233,02977,AED,ZEROC_AED,5YEAR
TKS,010690235,02977,AED,ZEROC_AED,7YEAR
TKS,010690236,02977,AED,ZEROC_AED,10YEAR

Answer 1

此oneliner打印fileB的不匹配行：

$ cut -d, -f1,5 fileA | xargs -n1 -I{} grep {} fileB | cat - fileB | sort | uniq -u
TKS,010690226,02977,AED,ZEROC_AED,3YEAR
TKS,010690233,02977,AED,ZEROC_AED,5YEAR
TKS,010690236,02977,AED,ZEROC_AED,10YEAR

说明：

首先合并fileA的字段1和5：

$ cut -d, -f1,5 fileA
ZEROC_ZAR,3YEAR
ZEROC_AED,4YEAR
ZEROC_ZAR,5YEAR
ZEROC_AED,7YEAR

使用这些字符串来grep fileB中的匹配行：

$ cut -d, -f1,5 fileA | xargs -n1 -I{} grep {} fileB
TKS,010690231,02977,AED,ZEROC_AED,4YEAR
TKS,010690235,02977,AED,ZEROC_AED,7YEAR

然后使用cat - fileB | sort将这两行与fileB的内容合并：

$ cut -d, -f1,5 fileA | xargs -n1 -I{} grep {} fileB | cat - fileB | sort
TKS,010690226,02977,AED,ZEROC_AED,3YEAR
TKS,010690231,02977,AED,ZEROC_AED,4YEAR
TKS,010690231,02977,AED,ZEROC_AED,4YEAR
TKS,010690233,02977,AED,ZEROC_AED,5YEAR
TKS,010690235,02977,AED,ZEROC_AED,7YEAR
TKS,010690235,02977,AED,ZEROC_AED,7YEAR
TKS,010690236,02977,AED,ZEROC_AED,10YEAR

最后，使用uniq -u删除重复的行：

$ cut -d, -f1,5 fileA | xargs -n1 -I{} grep {} fileB | cat - fileB | sort | uniq -u
TKS,010690226,02977,AED,ZEROC_AED,3YEAR
TKS,010690233,02977,AED,ZEROC_AED,5YEAR
TKS,010690236,02977,AED,ZEROC_AED,10YEAR

比较两个文件中的两个差异字段
