提交前查看更改 - Shell-Bash

在使用Shell-Bash进行开发时，为了避免将错误或不想提交的更改推送到代码库，建议在提交前进行更改的检查。

以下是一些常用的Shell-Bash命令和工具，可以帮助程序员提交前查看更改：

Git status

运行 git status 命令将显示未提交的更改。程序员可以在提交前查看所做的更改，确保所有更改都正确，并且没有不必要的更改。

```bash
$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   file1.txt
        modified:   file2.txt

no changes added to commit (use "git add" and/or "git commit -a")

## Git diff

```git diff``` 命令将显示未提交的更改之间的差异。

```markdown
```bash
$ git diff
diff --git a/file1.txt b/file1.txt
index 7b7b5c2..f630ce4 100644
--- a/file1.txt
+++ b/file1.txt

-Hi there!
+Hello there!

## Git add -p

```git add -p``` 命令允许程序员查看并选择要包含在提交中的更改。

```markdown
```bash
$ git add -p file1.txt
diff --git a/file1.txt b/file1.txt
index 7b7b5c2..f630ce4 100644

+++ b/file1.txt

## Git commit --verbose

```git commit --verbose``` 命令将显示提交的更改及其差异。当程序员提交时，可以查看更改，确保没有错误或不必要的更改。

```markdown
```bash
$ git commit --verbose
diff --git a/file1.txt b/file1.txt
index 7b7b5c2..f630ce4 100644

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.

总体而言，在提交之前仔细检查更改可以帮助程序员避免造成问题和错误。通过使用上述命令和工具，程序员可以轻松地查看他们所做的更改，确保他们在提交前进行了正确的修改和测试。
