A little bit of feeling-the first time I almost never read a book.

What I saw at first, what I learned, and how I learned it slowly with the accumulation of time, how I thought about similar knowledge. When I came back, I could find that what I understood became something I understood, think of his reasons and solutions.

It is hard to say that it is a kind of feeling, but this is the way to really turn knowledge into your own.

I have read the shell script Learning Guide again and found that I have read the first chapter, and I have found many places that I have not noticed or are not concerned about before:

Core transfer storage, at that time, in the annotation, it was just a little simpler, but in the past few days, just learning unix signal settings and capturing, involved in saving the core, this time again, to understand the meaning of this paragraph. When a serious signal occurs, if the default processing method is adopted, + core will be processed.

Processing text lines is also a little bit slow, and more feel the power of plain text, read again, I have a real feeling about the combination of the custom tool and unix mentioned in this section.

Regular Expression, very useful!

If you have time to read the books you have read, you may find the gap between yourself and the time!
