Too Much Scrolling
The last few quizzes in the previous section had you scrolling and scrolling through the patch output just to get to the right commit so you could see its info. Wouldn't it be super handy if you could just display a specific commit's details without worrying about all of the others in the repo?
There are actually two ways to do this!
- providing the SHA of the commit you want to see to
git log - use a new command
git show
They're both pretty simple, but let's look at the git log way and then we'll look at git show.
You already know how to "log" information with:
git loggit log --onelinegit log --statgit log -p
But did you know, you can supply the SHA of a commit as the final argument for all of these commands? For example:
$ git log -p fdf5493
By supplying a SHA, the git log -p command will start at that commit! No need to scroll through everything! Keep in mind that it will also show all of the commits that were made prior to the supplied SHA.
New Command: git show
The other command that shows a specific commit is git show:
$ git show
Running it like the example above will only display the most recent commit. Typically, a SHA is provided as a final argument:
$ git show fdf5493
What does git show do?
The git show command will show only one commit. So don't get alarmed when you can't find any other commits - it only shows one. The output of the git show command is exactly the same as the git log -pcommand. So by default, git show displays:
- the commit
- the author
- the date
- the commit message
- the patch information
However, git show can be combined with most of the other flags we've looked at:
--stat- to show the how many files were changed and the number of lines that were added/removed-por--patch- this the default, but if--statis used, the patch won't display, so pass-pto add it again-w- to ignore changes to whitespace
How many rulesets are added to the CSS by commit 8d3ea36?
Both .read-more and .read-more::after were added.
There's a commit with the message "Convert social links from text to images". How many files were changed by this commit?
Try using git log --oneline to find the SHA of the commit in question. Then pass the SHA to either git log --stat or git show --stat.
请记住，在你刚开始使用Git时，能够显示仓库的历史记录可能会特别有用，
