You need to quickly show commit changes in Git for a fast workflow. We use git diffand git showand various options to help you show the exact commit changes you need.

We use gitrevisionsthe option switch to find shortcuts for common use cases for Git to show the changes in a commit.

git diff <commit_ref>^!Using Show Committed Changes in Git

This is a neat and tidy way to quickly show the changes in a specific commit. It uses a gitrevisions <rev>^!shortcut that packs all the find functionality into one short line of code.

git diff <commit_ref>^!

<commit_ref>^!The short name refers to the commit <commit_ref>, but not all of its ancestors.

Essentially, this means that it only shows the commit <commit_ref>. git diffThe command then only shows the changes made by this commit.

Use in Git git diff <commit_ref>~ <commit_ref>to show the changes of Commit

gitrevisionsA range <commit_ref>~..<commit_ref>represents commits that we can <commit_ref>reach from, but not from their ancestors.

Therefore, it only represents <commit_ref>and not its ancestors.

In git diff, it is git diff <commit_ref>~ <commit_ref>the same as , and shows <commit_ref>the changes between and its immediate parent.

git diff <commit_ref>~ <commit_ref>

Therefore, this shows only <commit_ref>the changes made in the commit.

In Git, git diff <commit_ref>^ <commit_ref>use

<commit-ref>^Refers to the first parent of a commit.

git diff <commit_ref>^ <commit_ref>

It shows <commit_ref>the changes between and its first parent. This <commit_ref>is the same as if only the changes were made in commit .

Use file scope options in Git to show commit changes only in specific files/file types

We can pass file scope options to all the above methods to show changes only in specific files or file types.

git diff <commit_ref>^! <file|file type>

Quick Alternative – Use git showthe command and options to show committed changes in Git

We can use the command with a clever option git showto only show the diffs made by a commit.

We'll use it as a shortcut here.

git show --color --pretty=format:%b <commot_ref>

If we pass these options, git showonly commit changes will be shown.

Pro tip: This also works for or 工作树in . fails because has no ancestor.根提交第一次提交git diffRoot CommitRoot Commit

We see that fails git diffdue to Root Commit, but git showworks.

Use git showan alias with as a quick shortcut to show committed changes in Git

We saw above that we need to pass a number of options git showto show only the differences in commits.

We can create a shortcut ~/.gitconfigfor this long command by setting a in the ./configure_command file .alias

nano ~/.gitconfig

[aliases]
od = show --color --pretty=format:%b

We add an alias odor Only Difference. Then we can use it as a shortcut.

git od <commit_ref>

We can write quick shortcuts to show the most recent commit changes by using clever use of and gitrevisionslike .^~

In Git, use git diff HEAD^ HEADthe command to display the most recent commit changes.

HEADRefers to the latest commit.

git diff HEAD^ HEAD

It shows HEADthe difference between the or most recent commit and its parent.

This means it only shows its changes (latest commit).

Show changes across commits in Git

You can use ~ gitrevisionsthe suffix to jump back to HEADthe nth ancestor of and show the changes in that commit.

git diff HEAD~2 HEAD~1

It will show HEADthe difference between the second ancestor and the first ancestor of the or most recent commit.

So it will show the changes in either the first ancestor commit or the second most recent commit.
