How does git view modification history

Sometimes when comparing the code, I see some changes, but I don't know the author and reason of the change, and I don't know the corresponding BUG number, that is to say, there is no way to find out the specific reason for these changes.

[note]: a file can be changed for a limited number of times, and each submission of code modification will be described by commit. We can start here.

Switch to the directory

First change to the directory where the file you want to view is located:

Cd packages/apps/Mms/src/com/android/mms/ui/

2. Git log-pretty

Then use the following command to list the history of all changes to the file. Note that here we focus on a specific file, not the git library. If it is a library, there are a lot of changes.

Git log-- pretty=oneline file name

III. Git show

As shown above, what is printed is the history of all the changes to the file MessageItem.java. The long string of numbers at the front of each line is the hash value formed by each submission, and then you can use git show to display the specific changes.
