All scripts in libexec/ (excluding pyenv) are called through pyenv, therefore the shebang lines are not necessary. On some systems this provides a measurable increase in performance of the shell prompt. Related to pyenv/pyenv-virtualenv#259

# Summary: Run an executable with the selected Python version
|
|
#
|
|
# Usage: pyenv exec <command> [arg1 arg2...]
|
|
#
|
|
# Runs an executable by first preparing PATH so that the selected Python
|
|
# version's `bin' directory is at the front.
|
|
#
|
|
# For example, if the currently selected Python version is 2.7.6:
|
|
# pyenv exec pip install -rrequirements.txt
|
|
#
|
|
# is equivalent to:
|
|
# PATH="$PYENV_ROOT/versions/2.7.6/bin:$PATH" pip install -rrequirements.txt
|
|
|
|
