Question

我正在尝试使用awk来查找使用file1作为匹配条件的file2和$5之间的差异。我认为awk会起作用，但截至目前，它似乎输出了两个文件之间的共同点。我也尝试用相同的结果反转文件。谢谢你:)。

awk with current output

awk 'FNR==NR {a[$5]; next} $5 in a' file1 file2
chr10    102586755   102586862   chr10:102586755-102586862   PAX2-1650|gc=63
chr10    102587289   102587450   chr10:102587289-102587450   PAX2-1651|gc=65

awk 'FNR==NR {a[$5]; next} $5 in a' file2 file1
chr10    102586755   102586862   chr10:102586755-102586862   PAX2-1650|gc=63
chr10    102587289   102587450   chr10:102587289-102587450   PAX2-1651|gc=65

文件1

chr10    102586755   102586862   chr10:102586755-102586862   PAX2-1650|gc=63
chr10    102587289   102587450   chr10:102587289-102587450   PAX2-1651|gc=65
chr10    102732659   102732803   chr10:102732659-102732803   unknown-1652|gc=59.4
chr10    102732875   102733044   chr10:102732875-102733044   unknown-1653|gc=61.3

file2的

chr10    102586755   102586862   chr10:102586755-102586862   PAX2-1650|gc=63
chr10    102587289   102587450   chr10:102587289-102587450   PAX2-1651|gc=65
chr10    102732659   102732803   chr10:102732659-102732803   C10ORF2-1652|gc=59.4
chr10    102732875   102733044   chr10:102732875-102733044   C10ORF2-1653|gc=61.3

所需的输出

chr10    102732659   102732803   chr10:102732659-102732803   C10ORF2-1652|gc=59.4
chr10    102732875   102733044   chr10:102732875-102733044   C10ORF2-1653|gc=61.3

编辑：也许这是awk

awk 'NR==FNR{a[$5];next} !($5 in a)' file1 file2

您似乎只需使用faces[i].x = faces[i].x >= 0 ? faces[i].x : 0; faces[i].y = faces[i].y >= 0 ? faces[i].y : 0; faces[i].width = faces[i].x + faces[i].width > testMat.cols ? testMat.cols - faces[i].x : faces[i].width; faces[i].height = faces[i].y + faces[i].height > testMat.rows ? testMat.rows - faces[i].y : faces[i].height;而不是!($5 in a)作为打印条件：

$5 in a

使用awk使用特定字段查找两个文件中的差异
