Viewing A Specific Commit_12

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 log
• git log --oneline
• git log --stat
• git 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
• -p or --patch - this the default, but if --stat is used, the patch won't display, so pass -p to 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，

我们需要知道提交中存储的内容，以及在提交之后如何查看它，
