[英]join files and create index
I want to join two files and index them in a new column as show below : 我想加入两个文件并在新列中为它们建立索引,如下所示:
file A 文件A
apple 1 2 3 4 5 6
banana 3 2 4 4 5 6
orange 2 3 4 5 6 7
pear 2 4 5 6 3 5
file B 文件B
apple 1 3 4 5 6 7
grapes 4 5 6 4 3 6
melon 3 4 5 2 5 1
orange 2 4 5 6 7 8
I want to compare the two files based on first two columns, and output the common rows from file A and then add unique rows from both file A and file B and index them as shown below 我想比较基于前两列的两个文件,并输出文件A的公共行,然后添加文件A和文件B的唯一行并为其编制索引,如下所示
output: 输出:
apple 1 2 3 4 5 6 both
orange 2 3 4 5 6 7 both
banana 3 2 4 4 5 6 fileA
pear 2 4 5 6 3 5 fileA
grapes 4 5 6 4 3 6 fileB
melon 3 4 5 2 5 1 fileB
comm
compares two files and reports which lines occur in one, the other or both: comm
比较两个文件,并报告哪些行出现在一个,另一个或两个行中:
comm -2 <(cut -f1 -d' ' fileA | sort)
<(cut -f1 -d' ' fileB | sort) \
| sed $'/\t/{s/$/ both/;s/\t//};/ /!s/$/ fileA/' \
| join -o1.1,2.2,2.3,2.4,2.5,2.6,2.7,1.2 - fileA \
| sort -k8
cut -f1 -d' ' fileA \
| grep -vFf- fileB \
| sed 's/$/ fileB/'
As you can see, the pipeline is pretty complicated. 如您所见,管道非常复杂。 If you plan to make changes to the code, consider moving to a more powerful language like Perl.
如果您打算更改代码,请考虑使用功能更强大的语言,例如Perl。
