# Summary: Print the latest installed or known version with the given prefix
|
|
# Usage: pyenv latest [-k|--known] <prefix>
|
|
#
|
|
# -k/--known Select from all known versions instead of installed
|
|
# -b/--bypass (internal) On a resolution failure, do not print an error message
|
|
# but rather print the argument unchanged
|
|
# -f/--force (internal) Same as -b but also do not return a failure exit code
