## 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 or you can use our binary: [01exec](https://assets.01-edu.org/devops-branch/01exec) |
||||||
|
> If our binary is not working in your environment, 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 |
