Question

我正在尝试使用awk将file1与file2匹配，并在单独的文件中打印匹配的行。 File1是〜4MB，我得到以下错误，我似乎无法解决它。谢谢你:)。

awk 'NR==FNR{c[$0]; next} ($0 in c)' RS="," file1.txt RS="\n" file2.txt > match.txt

awk：超出程序限制：最大字段数= 32767 FILENAME =“sort.2.txt”FNR = 1 NR = 1

File1中

chr1:3063265-3063458 AVP:exon.3 8.55959
chr1:947806-947967 RSPO4:exon.3 246.54
chr2:12758246-12758422 CTD-2192J16.22:exon.2;MAN2B1:exon.1;MAN2B1:exon.20;MAN2B1:exon.22 221.483
chr2:57975642-57975745 KIF5A:exon.1;KIF5A:exon.23;KIF5A:exon.26 222.932

文件2

AVP
KIF5A

所需的输出

chr1:3063265-3063458 AVP:exon.3 8.55959
chr2:57975642-57975745 KIF5A:exon.1;KIF5A:exon.23;KIF5A:exon.26 222.932

Answer 1

你可以尝试，

awk '
    FNR==NR{d[$0]; next;}          #Store each key to find, from file2
    {                              #for each line in file1
        for(k in d){               #for each key in d (file2)
            pat="(^|;)"k":";       #pattern to search (regular expression)
            if($2 ~ pat){
                print;             #print if match with RE
                break;
            }
        }
    }' file2 file1

你明白了，

chr1:3063265-3063458 AVP:exon.3 8.55959
chr2:57975642-57975745 KIF5A:exon.1;KIF5A:exon.23;KIF5A:exon.26 222.932

awk将file1与file2匹配并输出匹配项
