Say I have a test output generated by cat some_file | grep some_text, and the output is like the following:

some text: 123123
some text: 123123
some text: 123123
some text: 123123
some text: 345345
some text: 123123
some text: 345345
some text: 345345

I want to have a summary of each line's frequency from this text like:

some text: 345345 => 3
some text: 123123 => 5

How to do that in bash?

Does "some text" change? ie, do you want to aggregate on the final column? – William Pursell Dec 29 '21 at 17:05

You probably just want `... | sort | uniq -c` – William Pursell Dec 29 '21 at 17:06
