-I, --libdir libdir

Include libdir in the search path for required modules.

-r, --require module

Require module before executing rakefile.

Rakefile location

-f, --rakefile filename

Use filename as the rakefile to search for.

-N, --no-search, --nosearch

Do not search parent directories for the Rakefile.

-G, --no-system, --nosystem

-R, --rakelib rakelibdir, --rakelibdir rakelibdir

Auto-import any .rake files in rakelibdir (default is ‘rakelib’)

-g, --system

Use system-wide (global) rakefiles (usually ~/.rake/*.rake).



Enable full backtrace. out can be stderr (default) or stdout.

-t, --trace=out

Turn on invoke/execute tracing, enable full backtrace. out can be stderr (default) or stdout.

-n, --dry-run

Do a dry run without executing actions.

-D, --describe [pattern]

Describe the tasks (matching optional pattern), then exit.

-W, --where [pattern]

Describe the tasks (matching optional pattern), then exit.

-P, --prereqs

Display the tasks and dependencies, then exit.

-e, --execute code

Execute some Ruby code and exit.

-p, --execute-print code

Execute some Ruby code, print the result, then exit.

-E, --execute-continue code

Execute some Ruby code, then continue with normal task processing.


-v, --verbose

Log message to standard output.

-q, --quiet

Do not log messages to standard output.

-s, --silent

Like --quiet, but also suppresses the ‘in directory’ announcement.

-X, --no-deprecation-warnings

Disable the deprecation warnings.
