This article mainly introduces linux how to view the file content of a specific line of data, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Idea: through the combination of head and tail instructions, head instruction to see how many lines before, tail instruction to see how many lines behind, for example: a log log has many lines, we get his 40th line of data, the idea is to first use head to get the first 40 lines, and then tail to get the last line, so we get the data of line 40.

Directive:

Head-n 40 2017_08_28.log | tail-n 1

Specific performance comparison:

Get the first 40 lines

You can see that the data on the last line is "right-click rename"

Get 40th row of data

We can see that the data we got is consistent with the previous data, and we have achieved the desired goal.
