git自动压缩提交的脚本

可以将当前未提交的代码自动执行

git add
git commit
git squash

Git 命令安装指南

1. 创建脚本目录

如果目录不存在，创建它：

mkdir -p ~/.local/bin

2. 创建脚本文件

vim ~/.local/bin/git-squash

将完整的脚本代码复制到此文件中。

3. 设置脚本权限

chmod +x ~/.local/bin/git-squash

4. 配置 PATH

编辑 shell 配置文件（根据你使用的 shell 选择）：

# 对于 bash
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc# 或对于 zsh
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc

重新加载配置：

source ~/.bashrc  # 或 source ~/.zshrc

5. 创建 Git 别名

git config --global alias.allen-squash '!git-squash'

6. 验证安装

检查脚本是否可执行：

ls -l ~/.local/bin/git-squash

检查脚本是否在 PATH 中：

which git-squash

检查 git 别名是否设置成功：

git config --get-regexp alias.*squash

7. 使用方法

可以通过以下两种方式使用：

# 直接使用脚本
git-squash# 或使用 git 别名
git allen-squash

8. 常见问题排查

命令未找到

检查 PATH：

echo $PATH | grep -o ~/.local/bin

检查脚本权限：

ls -l ~/.local/bin/git-squash

检查 git 别名：

git config --list | grep allen-squash

管理别名

# 删除别名
git config --global --unset alias.allen-squash# 修改别名
git config --global alias.allen-squash '!git-squash'

编辑脚本

vim ~/.local/bin/git-squash

9. 备份建议

建议进行以下备份：

# 备份脚本
cp ~/.local/bin/git-squash ~/.local/bin/git-squash.backup# 备份 git 配置
cp ~/.gitconfig ~/.gitconfig.backup

10. 更新脚本

如需更新脚本：

# 编辑脚本
vim ~/.local/bin/git-squash# 确保权限正确
chmod +x ~/.local/bin/git-squash

注意事项

确保 ~/.local/bin 目录存在并在 PATH 中
确保脚本具有可执行权限
重启终端或重新加载配置文件后更改才会生效
建议在使用前先进行配置备份
如果遇到权限问题，检查用户权限和文件权限

故障排除

如果命令不能正常工作，请按以下步骤检查：

确认脚本位置：
- 检查 ~/.local/bin/git-squash 是否存在
- 确认文件权限是否正确
检查 PATH 设置：
- 确认 ~/.local/bin 在 PATH 中
- 检查 shell 配置文件是否正确加载
验证 git 别名：
- 检查别名是否正确设置
- 确认 git 配置文件是否正确
