# lessecho.1

`lessecho` — expand metacharacters

## 名称

`lessecho`

## 概要

`lessecho [-a] [-ox] [-cx] [-pn] [-dn] [-mx] [-nn] [-ex] file ...`

`lessecho --version`

## 描述

`lessecho` 是一个简单的程序，它将自身的参数回显到标准输出。但输出中的任何元字符前都会加上一个"转义"字符，默认为反斜杠。`lessecho` 由 `less` 内部调用，不打算供用户直接使用。

## 选项

下面是选项的摘要。

`-ex`

指定 `x`（而非反斜杠）作为元字符的转义字符。如果 `x` 为 `-`，则不使用转义字符，包含元字符的参数改用引号包围。

`-ox`

指定 `x`（而非双引号）作为开引号字符，在使用 `-e-` 选项时使用。

`-cx`

指定 `x` 作为闭引号字符。

`-pn`

以整数形式指定 `n` 作为开引号字符。

`-dn`

以整数形式指定 `n` 作为闭引号字符。

`-mx`

指定 `x` 为一个元字符。默认情况下，没有任何字符被视为元字符。

`-nn`

以整数形式指定 `n` 为一个元字符。

`-fn`

以整数形式指定 `n` 作为元字符的转义字符。

`-a`

指定对所有参数加引号。默认仅对包含元字符的参数加引号。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man1/lessecho.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
