# replacing last command and execute it

For example

```
$ echo "hello world world world"                   
hello world world world
```

If you want to replace `world` with `universe` you can do

```
# If you use ZSH you can press `tab` at the end of the line and it will replace
# the whole line with the actuall command
$ ^world^universe
$ echo "hello universe world world"
```

As you can see, it only replace the first matching word.

If you want it to replace the whole match:

```
# zsh
$ ^world^universe^:G

# bash
$^world^universe^&
```

**Don't use it in production**\
I tend to use `fc` command which allow me to edit the command in my editor first

## 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://til.yulrizka.com/unix/replacing-last-command-and-execute-it.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.
