查找文件中的重复行并计算每行重复多少次？ [英] Find duplicate lines in a file and count how many time each line was duplicated?

问题描述

假设我有类似以下文件的文件：

Suppose I have a file similar to the following:

123 
123 
234 
234 
123 
345

我想要多少次'123'被复制，'234'被复制多少次等等。
所以理想情况下，输出将是：

I would like to find how many times '123' was duplicated, how many times '234' was duplicated, etc. So ideally, the output would be like:

123  3 
234  2 
345  1

推荐答案

假设每行有一个数字：

sort <file> | uniq -c

您可以使用更详细的 - count flag与GNU版本，例如，在Linux上：

You can use the more verbose --count flag too with the GNU version, e.g., on Linux:

sort <file> | uniq --count
