标签： linux bash macos

所以我试图使用＆＃34; uinq＆＃34;来打印一个独特的输出。在bash中实用，但它似乎对我没用。

这是我的文件，其中包含以下内容： -

正如你可能已经注意到的除了第8个字段，每个＆＃34; kext＆＃34;有一个冗余条目。我尝试使用cat myfile | uniq -f8，但这不起作用。

任何帮助将不胜感激。

uniq要求对其输入进行排序。实现这一点，如下所示：

sed -E -e 's/OSKext 0x[^[:space:]]+ /OSKext ELIDED /g' | sort | uniq

...在stdin输入时产生：

awk救援！

不求助于排序（双关语）

$ awk '{k=$8; $8=""} !a[$0]++{$8=k; print}' file | wc -l

17

以输入文件的相同顺序打印唯一条目模数第8个字段。

如果你不想保留这个领域，那就更简单...... 

$ awk '{$8="REMOVED"} !a[$0]++' file
