## Input redirection
### Instructions
In this exercise you will make a script `input-redirection.sh` .
This script will read from an here document (`heredoc`).
Usually this technique is used to programmatically generate scripts or configuration files receiving some multiline input.
The script will create a file `show-info.sh` that will run the command `cat` with `-e` as argument.
The input to `cat` will be passed using `heredoc` . Running `show-info.sh` will output some useful information about three common environment variables.
> The environment variables are `PWD`, `PATH` and `USERNAME`.
### Usage
- First generate the script programmatically:
```console
$ ./input-redirection.sh
$
```
- Then run the generated script:
```console
$ bash ./show-info.sh
The current directory is: current/path/example$
The default paths are: /first_path:/second_path:/third_path$
The current user is: your_name$
$
```
### Hints
You will need to mix more than one redirection tool:
- `>` will be useful to create `show-info.sh` .
- `<<` is the `heredoc` redirection.
- To start playing with `heredoc` you can try `wc -l <<EOF` , type some random things, then write `EOF` on a new line and press `Enter` .
- Don't forget you can use `echo` to write into `show-info.sh` .
