∴ rvm [all|all-gemsets|<ruby>,...|<path>] [--verbose|--summary|--yaml|--json] do <command> ... ∴ rvm in <path> do <some-command> ... ∴ rvm-exec [all|all-gemsets|<ruby>,...|<path>] [--verbose|--summary|--yaml|--json] <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.
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
in- works with path and will additionally
cdto 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
If using the set do operation when scripting, use rvm-exec (usually installed to
~/.rvm/bin/rvm instead will cause RVM to spawn a bash shell, which is undesireable in the context of process monitoring.
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
which ruby in the current directory, loading a
∴ rvm . do which ruby
rake test in the project directory, loading a
∴ rvm in /path/to/project do rake test
