## Usage $ rvm [all|all-gemsets|<ruby>,...|<path>] [--verbose|--summary|--yaml|--json] do <command> ... $ rvm in <path> do <some-command> ... Executes arbitrary commands against given a set of rvm environments. Without additional flags it will exec the command directly without printing out extra rvm information. ## Selectors: - `all` - execute command in the default gemset of all rubies - `all-gemsets` - execute command in the all gemset for all rubies - `<ruby>,...` - list of rubies to use, allows short versions or gemsets - `<path>` - use ruby from the given path/project ## Modifiers: - `in` - works with path and will additionally `cd` to the given directory - `--verbose` - display one line details about ruby/gemset - `--summary` - hide output and display summary of failures/success list only - `--yaml` - hide output and display yaml summary of failures/success list only - `--json` - hide output and display json summary of failures/success list only - `--summary` - print out a summary of the commands run - `-S` - specify the script file to load and run ## Examples: To execute `ruby -v` against all installed rubies and aliases, you would run: $ rvm all do ruby -v If you want to execute it against a specific ruby (without extra logging / data printed by rvm as is done with normal set operations), you can instead do: $ rvm ree do ruby -v Since it is a set operation, normal ruby specifiers will work. As an example, to run `gem list` against **1.9.2** and **1.8.7** and prefix with ruby name, you would run: $ rvm 1.9.2,1.8.7 --verbose do gem list Or, to execute `gem env` against all gemsets: $ rvm all-gemsets do gem env To execute `which ruby` in the current directory, loading a `.rvmrc`: $ rvm . do which ruby To execute `rake test` in the project directory, loading a `.rvmrc`: $ rvm in /path/to/project do rake test For more information, refer to the rvm set operations.
