## auto-exec-bin

### Instructions

Create a file `auto-exec-bin.sh`, which will make a binary with the name `01exec` in `~/myBins` executable from any working directory.

You can use any binary from your choice to test your script.

> You can pick any binary for the tests!

Expected Output:

```console
$ ls -l ~/myBins # the binary
01exec
$ 01exec
error: command not found: 01exec
$ ./auto-exec-bin.sh
$ 01exec
Hello 01 Scripting Pool
$ cd /{random-path} && 01exec
Hello 01 Scripting Pool
$
```

### Hints

`PATH` environment variable is a variable where the shell search for the binaries for the execution.

When you put a command the shell will search for binary in `PATH` folders

fix(auto-exec-bin): fix test bug - replace bash command with source to update current bash PATH and not a sub-bash one - replace binary with simple bash script - image has no access to internet - update subject accordingly 2 years ago			`You can use any binary from your choice to test your script.`
