# 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.
|
|
#
|
|
# 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
|
|
