# bin-version-check [](https://travis-ci.org/sindresorhus/bin-version-check)
> Check whether a binary version satisfies a [semver range](https://github.com/isaacs/node-semver#ranges)
Useful when you have a thing that only works with specific versions of a binary.
## Install
```sh
$ npm install --save bin-version-check
```
## Usage
```sh
$ curl --version
curl 7.30.0 (x86_64-apple-darwin13.0)
```
```js
var binVersionCheck = require('bin-version-check');
binVersionCheck('curl', '>=8', function (err) {
if (err) {
throw err;
//=> InvalidBinVersion: curl 7.30.0 does not satisfy the version requirement of >=8
}
});
```
## CLI
```sh
$ npm install --global bin-version-check
```
```
$ bin-version-check --help
Usage
bin-version-check <binary> <semver-range>
Example
$ curl --version
curl 7.30.0 (x86_64-apple-darwin13.0)
$ bin-version-check curl '>=8'
curl 7.30.0 does not satisfy the version requirement of >=8
Exits with code 0 if the semver range is satisfied and 1 if not
```
