"Linux/ubuntu Learning 11" Git view a file's modification history

Sometimes when compared to the code, see some changes, but not clear the author and reason for the change, do not know the corresponding bug number, that is, there is no way to find out the specific reasons for these changes ~

"Note": A file changes are limited, and each time the code changes submitted will have a commit description, we can start from here;

One, switch to the directory

First switch to the directory where you want to view the files:

CD packages/apps/mms/src/com/android/mms/ui/

Second, git log--pretty

Then use the following command to list all the changes to the file history, note that the focus here on a specific file, not the Git library, if it is a library, the changes can be more ~

git log--pretty=oneline file name

Such as:

Third, git show

As shown above, the print is all the changes to the file Messageitem.java history, the first long list of each line is the hash value of each commit, and then use git show to display a specific change of the changes ~

356f6def9d3fb7f3b9032ff5aa4b9110d4cca87e

The results are as follows:

[Email protected]:/android_src/packages/apps/mms/src/com/android/mms/ui# git show 356f6def9d3fb7f3b9032ff5aa4b9110d4cca87e
