# Hello World
|
|
|
|
Welcome to Hello World on Exercism's Bash Track.
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
|
|
|
## Instructions
|
|
|
|
The classical introductory exercise. Just say "Hello, World!".
|
|
|
|
["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) is
|
|
the traditional first program for beginning programming in a new language
|
|
or environment.
|
|
|
|
The objectives are simple:
|
|
|
|
- Write a function that returns the string "Hello, World!".
|
|
- Run the test suite and make sure that it succeeds.
|
|
- Submit your solution and check it at the website.
|
|
|
|
If everything goes well, you will be ready to fetch your first real exercise.
|
|
|
|
Unlike many other languages here, bash is a bit of a special snowflake.
|
|
If you are on a Mac or other unix-y platform, you almost definitely
|
|
already have bash. In fact, anything you type into the terminal is
|
|
likely going through bash.
|
|
|
|
The downside to this is that there isn't much of a development
|
|
ecosystem around bash like there is for other languages, and there are
|
|
multiple versions of bash that can be frustratingly incompatible. Luckily
|
|
we shouldn't hit those differences for these basic examples, and if you
|
|
can get the tests to pass on your machine, we are doing great.
|
|
|
|
## Installation
|
|
|
|
As mentioned above, if you are on a unix-like OS (Mac OS X, Linux, Solaris,
|
|
etc), you probably already have bash.
|
|
|
|
## Testing
|
|
|
|
As there isn't much of a bash ecosystem, there also isn't really a de
|
|
facto leader in the bash testing area. For these examples we are using
|
|
[bats](https://github.com/bats-core/bats-core). You should be able to
|
|
install it from your favorite package manager, on OS X with homebrew
|
|
this would look something like this:
|
|
|
|
```
|
|
$ brew install bats-core
