# 检查并移除文本

> 在编辑文件前先检查精确的文本匹配。

用 Arka 在编辑文件前检查精确的文本匹配：

```bash theme={null}
arka text inspect README.md "old phrase"
arka text remove README.md "old phrase" --yes
arka text remove README.md "old phrase" --all --yes
```

移除操作默认会创建 `.bak` 备份。如不加 `--yes`，Arka 只会预览匹配数量而不做任何修改。当文件与文本清晰引用时，「inspect the text `old phrase` in README.md」这类自然语言请求也会被路由。
