有没有办法根据字段过滤文件中只出现一次的行?
Is there a way to filter a file for lines that only occur once, based on a field?
我有一个 "diff like" 文件,其中字段由制表符分隔。有没有办法只使用标准的 gnu 工具只获取出现一次的行,如果它们的第二个字段相等,则两条线相等?
本质上,我只想过滤此文件的新行和删除行,而不是编辑行。
文件首先按第二列(名称)排序,然后按第一列排序(先减后加)。

经过一些 awk 的争论,我想到了这个。
它计算第二个字段的所有出现次数,然后打印那些等于 1 的次数。
awk -F $'\t' '{count[]++} count[] == 1'
