 The following options in this section are only recognized on the

-[[opt-defaults-torrc]] **--defaults-torrc** __FILE__::
+[[opt-defaults-torrc]] **`--defaults-torrc`** __FILE__::
     Specify a file in which to find default values for Tor options.  The
     contents of this file are overridden by those in the regular
     configuration file, and by those on the command line. (Default:
-    @CONFDIR@/torrc-defaults.)

-[[opt-ignore-missing-torrc]] **--ignore-missing-torrc**::
+[[opt-ignore-missing-torrc]] **`--ignore-missing-torrc`**::
     Specify that Tor should treat a missing torrc file as though it
     were empty. Ordinarily, Tor does this for missing default torrc files,
     but not for those specified on the command line.
 
-[[opt-hash-password]] **--hash-password** __PASSWORD__::
+[[opt-hash-password]] **`--hash-password`** __PASSWORD__::
     Generate a hashed password for control port access.

     Generate your keys and output your nickname and fingerprint.

+[[opt-serviceinstall]] **`--service install`** [**`--options`** __command-line options__]::

     command-line options. Current instructions can be found at

-[[opt-quiet]] **--quiet**|**--hush**::
+[[opt-quiet]] **`--quiet`**|**`--hush`**::
     Override the default console logging behavior.  By default, Tor
     starts out logging messages at level "notice" and higher to the
     console.  It stops doing so after it parses its configuration, if
     the configuration tells it to log anywhere else.  These options
-    override the default console logging behavior.  Use the **--hush**

+[[opt-keygen]] **`--keygen`** [**`--newpass`**]::

     for a relay, or only a fresh temporary signing key and
     certificate, if you already have a master key.  Optionally, you
     can encrypt the master identity key with a passphrase.  When Tor
     asks you for a passphrase and you don't want to encrypt the master
     key, just don't enter any passphrase when asked. +
  +
-    Use the **--newpass** option with --keygen only when you need to
-    add, change, or remove a passphrase on an existing ed25519 master
-    identity key. You will be prompted for the old passphase (if any),
-    and the new passphrase (if any).

-When generating a master key, you may want to use **--DataDirectory**

     File descriptor to read the passphrase from.  Note that unlike with the
     tor-gencert program, the entire file contents are read and used as
     the passphrase, including any trailing newlines.
     If the file descriptor is not specified, the passphrase is read
     from the terminal by default.
