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.
