+# Command Line Options
+
+<!--type=misc-->
+
+Node.js comes with a wide variety of CLI options. These options expose built-in
+debugging, multiple ways to execute scripts, and other helpful runtime options.
+
+To view this documentation as a manual page in your terminal, run `man node`.
+
+
+## Synopsis
+
+`node [options] [v8 options] [script.js | -e "script"] [arguments]`
+
+`node debug [script.js | -e "script" | <host>:<port>] …`
+
+`node --v8-options`
+
+Execute without arguments to start the [REPL][].
+
+_For more info about `node debug`, please see the [debugger][] documentation._
+
+
+## Options
+
+### `-v`, `--version`
+
+Print node's version.
+
+
+### `-h`, `--help`
+
+Print node command line options.
+The output of this option is less detailed than this document.
+
+
+### `-e`, `--eval "script"`
+
+Evaluate the following argument as JavaScript.
+
+
+### `-p`, `--print "script"`
+
+Identical to `-e` but prints the result.
+
+
+### `-c`, `--check`
+
+Syntax check the script without executing.
+
+
+### `-i`, `--interactive`
+
+Opens the REPL even if stdin does not appear to be a terminal.
+
+
+### `-r`, `--require module`
+
+Preload the specified module at startup.
+
+Follows `require()`'s module resolution
+rules. `module` may be either a path to a file, or a node module name.
+
+
+### `--no-deprecation`
+
+Silence deprecation warnings.
+
+
+### `--trace-deprecation`
+
+Print stack traces for deprecations.
+
+
+### `--throw-deprecation`
+
+Throw errors for deprecations.
+
+
+### `--trace-sync-io`
+
+Prints a stack trace whenever synchronous I/O is detected after the first turn
+of the event loop.
+
+
+### `--zero-fill-buffers`
+
+Automatically zero-fills all newly allocated [Buffer][] and [SlowBuffer][]
+instances.
+
+
+### `--track-heap-objects`
+
+Track heap object allocations for heap snapshots.
+
+
+### `--prof-process`
+
+Process v8 profiler output generated using the v8 option `--prof`.
+
+
+### `--v8-options`
+
+Print v8 command line options.
+
+
+### `--tls-cipher-list=list`
+
+Specify an alternative default TLS cipher list. (Requires Node.js to be built
+with crypto support. (Default))
+
+
+### `--enable-fips`
+
+Enable FIPS-compliant crypto at startup. (Requires Node.js to be built with
+`./configure --openssl-fips`)
+
+
+### `--force-fips`
+
+Force FIPS-compliant crypto on startup. (Cannot be disabled from script code.)
+(Same requirements as `--enable-fips`)
+
+
+### `--icu-data-dir=file`
+
+Specify ICU data load path. (overrides `NODE_ICU_DATA`)
+
+
+## Environment Variables
+
+### `NODE_DEBUG=module[,…]`
+
+`','`-separated list of core modules that should print debug information.
+
+
+### `NODE_PATH=path[:…]`
+
+`':'`-separated list of directories prefixed to the module search path.
+
+_Note: on Windows, this is a `';'`-separated list instead._
+
+
+### `NODE_DISABLE_COLORS=1`
+
+When set to `1` colors will not be used in the REPL.
+
+
+### `NODE_ICU_DATA=file`
+
+Data path for ICU (Intl object) data. Will extend linked-in data when compiled
+with small-icu support.
+
+
+### `NODE_REPL_HISTORY=file`
+
+Path to the file used to store the persistent REPL history. The default path is
+`~/.node_repl_history`, which is overridden by this variable. Setting the value
+to an empty string (`""` or `" "`) disables persistent REPL history.
