Usage rvm [Flags] [Options] Action [Implementation[,Implementation[,...]] Flags --head - with update, updates rvm to git head version. --rubygems - with update, updates rubygems for selected ruby --default - with ruby select, sets a default ruby for new shells. --debug - Toggle debug mode on for very verbose output. --trace - Toggle trace mode on to see EVERYTHING rvm is doing. --force - Force install, removes old install & source before install. --summary - Used with rubydo to print out a summary of the commands run. --jit - Used with rubinius install to build with JIT --latest - with gemset --dump skips version strings for latest gem. --gems - with uninstall/remove removes gems with the interpreter. --docs - with install, attempt to generate ri after installation. --reconfigure - Force ./configure on install even if Makefile already exists. Options -v|--version - Emit rvm version loaded for current shell -l|--level - patch level to use with rvm use / install --prefix - path for all rvm files (~/.rvm/), with trailing slash! --bin - path for binaries to be placed (~/.rvm/bin/) --source - src directory to use (~/.rvm/src/) --archives - directory for downladed files (~/.rvm/archives/) -S - Specify a script file to attempt to load and run (rubydo) -e - Execute code from the command line. -G|--gems - root gem path to use --patch - With MRI Rubies you may specify one or more full paths to patches for multiple, specify comma separated: --patch /.../.../a.patch,/.../.../.../b.patch -C|--configure - custom configure options. If you need to pass several configure options then append them comma separated: -C --...,--...,--... --nice - process niceness (for slow computers, default 0) --ree-options - Options passed directly to ree's './installer' on the command line. Action * usage - show this usage information version - show the rvm version installed in rvm_path use - setup current shell to use a specific ruby version reload - reload rvm source itself (useful after changing rvm source) implode - (seppuku) removes the rvm installation completely. This means everything in $rvm_path (~/.rvm). This does not touch your profiles, which is why there is an if around the sourcing scripts/rvm. update - upgrades rvm to the latest version. (If you experience bugs try this first with --head) reset - remove current and stored default & system settings. (If you experience odd behavior try this second) info - show the *current* environment information for current ruby debug - show info plus additional information for common issues install - install one or many ruby versions See also: http://rvm.beginrescueend.com/rubies/installing/ uninstall - uninstall one or many ruby versions, leaves their sources remove - uninstall one or many ruby versions and remove their sources wrapper - generates a set of wrapper executables for a given ruby with the specified ruby and gemset combination. Used under the hood for passenger support and the like. ruby - runs a named ruby file against specified and/or all rubies gem - runs a gem command using selected ruby's 'gem' rake - runs a rake task against specified and/or all rubies tests - runs 'rake test' across selected ruby versions specs - runs 'rake spec' across selected ruby versions monitor - Monitor cwd for testing, run `rake {spec,test}` on changes. gemset - gemsets: http://rvm.beginrescueend.com/gemsets/ gemdir - display the path to the current gem directory (GEM_HOME). srcdir - display the path to rvm source directory (may be yanked) fetch - Performs an archive / src fetch only of the selected ruby. list - show currently installed rubies, interactive output. http://rvm.beginrescueend.com/rubies/list/ package - Install a dependency package {readline,iconv,zlib,openssl} http://rvm.beginrescueend.com/packages/ notes - Display notes, with operating system specifics. Implementation * ruby - MRI/YARV Ruby (The Gold Standard) {1.8.6,1.8.7,1.9.1,1.9.2...} jruby - JRuby, Ruby interpreter on the Java Virtual Machine. rbx - Rubinius ree - Ruby Enterprise Edition, MRI Ruby with several custom patches for performance, stability, and memory. macruby - MacRuby, insanely fast, can make real apps (Mac OS X Only). maglev - GemStone Ruby, awesome persistent ruby object store. ironruby - IronRuby, NOT supported yet. Looking for volunteers to help. mput - shyouhei(mput)'s github repository, popular in Japan :) system - use the system ruby (eg. pre-rvm state) default - use rvm set default ruby and system if it hasn't been set. http://rvm.beginrescueend.com/rubies/default/ Resources: http://rvm.beginrescueend.com/ https://www.pivotaltracker.com/projects/26822
