问题描述
我搜索了论坛,但没有找到问题的答案. 我有一个看起来像这样的文件:
I searched the forum but did not found the answer to my question. I have a file that look like this :
chr left_pos right_pos 1 2596 3084 1 3084 5869 1 18500 21000 3 21000 21536 3 22872 23179我已经在第1列然后第2列对文件进行了排序: 如果第一列中的字段相同,我想在下一行中将字段3中的数字与字段2中的数字进行比较.如果是,则在行尾添加等于的标签.如果不等于,则不等于.
I already sorted ou the file on column one then column 2: I would like to compare the number in field 3 to the number in field 2 in the following line if the field in column one are identical. If yes add the label equal at the end of the line. If not add not equal.
输出应如下所示
chr left_pos right_pos 1 2596 3084 not_equal 1 3084 5869 equal 1 18500 21000 not_equal 3 21000 21536 not_equal 3 22872 23179 not_equal感谢您的帮助
推荐答案这应该对您有用:
awk 'NR==1 { print; next } { print $0, ($1 == a && $2 == b) ? "equal" : "not_equal"; a = $1; b = $3 }' file | column -t结果:
chr left_pos right_pos 1 2596 3084 not_equal 1 3084 5869 equal 1 18500 21000 not_equal 3 21000 21536 not_equal 3 22872 23179 not_equal更多推荐
