## Usage
```
  Usage: eisd <command> [options] <directories...>

  Options:
    -a, --async                             Execute commands async across all folders, output will be a mess
    -e, --allowErrors                       Allow errors (at default we stop when there is one). NOTE: always true when in async mode
    -y, --yarnWorkspaces                    Use yarn workspaces for the directories to run the command in
    -d, --envDirectories [environment_key]  Environment variable that contains the directories, for example a package.json config var would be: npm_config_myVar
    -v, --verbose                           More verbose output
    -h, --help                              output usage information
```

## Examples

`eisd 'yarn install' --ignoreRegex '^warning' --async client server testSetup/mockServer`

## Compatibility
Works on Linux and Mac, should also work on Windows (will test it soon). If not, create an issue and I will fix it. :-)
