rbpm (ruby path mangler) https://github.com/omp/rbpm Manage multiple Ruby installations with no black magic. NOTES rbpm only manages rubies located in the ~/.rubies directory. This behaviour can be changed by setting the RUBIES_PATH environment variable to some other location. rbpm does not display information about rubies it does not manage, such as any system-wide install. rbpm performs a substring match when selecting a ruby, using the highest matching directory when there are multiple matches. DEPENDENCIES bash (>= 4.0) coreutils (sort) findutils (xargs) INSTALLING Save the script to a safe location, then add the following function to your ~/.bashrc or equivalent file: rbpm() { source <(/path/to/rbpm.sh "${@}"); } INSTALLING RUBIES The path to the executable should look something like this: ~/.rubies/ruby-2.1.2/bin/ruby To install Ruby to this directory: $ wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.bz2 $ tar -xf ruby-2.1.2.tar.bz2 $ cd ruby-2.1.2 $ ./configure --prefix="${HOME}"/.rubies/ruby-2.1.2 $ make $ make install USAGE A sequence of commands showing rbpm in use: $ rbpm ls ruby-1.8.7-p374 ruby-1.9.3-p547 ruby-2.1.2 $ rbpm set 2.1 Adding /home/omp/.rubies/ruby-2.1.2/bin to PATH. $ rbpm ls ruby-1.8.7-p374 ruby-1.9.3-p547 * ruby-2.1.2 $ ruby -v ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux] $ rbpm set 1.9 Removing /home/omp/.rubies/ruby-2.1.2/bin from PATH.
