# Summary: Run an executable with the selected Ruby version

# Usage: rbenv exec <command> [arg1 arg2...]

# Runs an executable by first preparing PATH so that the selected Ruby
|
||||
# version's `bin' directory is at the front.
|
||||
# Runs an executable contained by the currently selected Ruby's bin
|
||||
# directory. Rough equivalent of:
|
||||
#
|
||||
# For example, if the currently selected Ruby version is 1.9.3-p327:
|
||||
# rbenv exec bundle install
|
||||
#
|
||||
# is equivalent to:
|
||||
# PATH="$RBENV_ROOT/versions/1.9.3-p327/bin:$PATH" bundle install
|
||||
# exec "$(rbenv prefix)/bin/$command" args...
