  alex - extract addresses from	message	headers	(only available	within the
  message handling system, mh)


  alex [+folder] [msgs]	[options]


  -address string
      Accepts an address that you type in, rather than taking an address from
      a	message. If any	-field option is specified, it is ignored.

  -alias filename
      Specifies	the name of the	alias file, in which aliases are placed. You
      must provide a file name or a dash (-) as	an argument with this option.
      There is no default value. If the	value given for	this option is -, or
      the option is not	specified, alex	will print the output to your screen.
      If you do	not give the full pathname of your alias file, alex will look
      for the alias file in your Mail directory, as specified in the Path
      field of your .mh_profile	file. If alex cannot locate the	alias file in
      the directory that you specify, it will ask you whether or not you wish
      to create	one.

      You can set up an	alias file to be used by alex in your .mh_profile;
      see mh_profile(4)	for more information.  Like other mail commands, alex
      uses the Aliasfile entry to find the alias file.


      Prevents any repetition of the same address in the output	of an alex
      command.	You can	use this option	when there are multiple	 occurrences
      of an address in an address group	and you	want just one  occurrence of
      it in your alias.	The default is -nocompress.

  -field name[ /name ... ]

      Specifies	the name of a header field. The	name of	the field is not
      case-sensitive. If you specify this option without providing an argu-
      ment, the	default	values are: -field reply-to/sender/from/to. You	can
      set up your own default values for the -field option in your
      .mh_profile. See mh_profile(4).

      Examples of field	names are From,	cc and To. You must not	type a colon
      after the	name of	a field.  When more field names	follow,	in the form
      /name, the message header	is searched for	each of	the fields in turn
      until one	is found. Only the first header	field found to contain an
      address is used; the rest	are ignored.

      The option -nofield excludes the named field.

      The special name,	all, means all fields, and can be used as a value for
      the -nofield option to override any default order	of header fields,
      otherwise	-field values are appended to any default values.

      Specifies	that any address replacements or appendings will apply to all
      occurrences of that alias	name. Normally,	if an alias name is entered
      in the alias file	more than once,	any actions performed by alex are
      performed	only on	the first occurrence of	that alias name.  The -global
      option ensures that any changes are made to all occurrences of the
      alias. Whenever this option is specified,	a message is broadcast to
      your screen telling you how many entries in the alias file have been

      Prints a list of the valid options for this command.

  -name	name
      Specifies	the alias name for address information extracted.  The alex
      command appends a	colon (:) to the name as required by mh-alias(4). If
      you do not specify this option,alex will print extracted addresses to
      your screen.  If you specify this	option,	you must provide an argument;
      there is no default value.


      Extracts addresses interactively.	Before adding each address of a	list
      of extracted addresses to	an alias group,	the mail system	will ask you
      whether you wish the address to be added.	The query prompt is written
      on the standard error output. The	default	is -noquery.


      Replaces existing	alias with the new list	of addresses. By default, if
      there is an existing alias with the same name as the one you are trying
      to create, alex appends the new address list to the old alias. If	an
      address appears in both address groups, it is still appended, so that
      it appears twice in the new alias. You can specify this explicitly by
      using the	-noreplace option. If you specify the -replace option, the
      new list of addresses replaces the existing group.  The default is

  -width n
      Specifies	the maximum width of your alias	file line. If an alias group
      extends beyond this length, it is	continued on the next line, with a
      backslash	(\) at end of the first	line. Any X.400	addresses which	are
      longer than the maximum line length specified by this option are
      automatically wrapped onto the next line.	This option affects the	for-
      mat of each individual entry when	it is implemented; any subsequent or
      previous entries in the alias file remain	the same. The default is 72


  The address line extraction utility alex extracts electronic mail addresses
  from message headers and prints the addresses	on your	screen or places
  them,	with a	specified alias	name, in an alias file.

  By default, alex searches for	addresses in the current message  in the
  current folder. You can list the messages you	wish alex to search giving a
  msgs argument.  You can also search messages in a different folder by	giv-
  ing a	+folder	argument.

  You define the fields	from which you want addresses by using combinations
  of field names with the -field option. You can also supply an	address	your-
  self as a value to the -address option. Results are printed either to	your
  screen or to a file in mh-alias(4) format.  Where there is an	address	group
  in the alias file with an alias name identical to one	you have specified in
  an alex command, it may be replaced  or the new addresses appended.  A copy
  of the original alias	file is	kept.

  By default, alex searches the	Reply-to:, Sender:, From: and To: header
  fields in that order until an	address	is found. You can set up your own
  default values for alex in your .mh_profile file; see	mh_profile(4).

  When giving options to the alex command, generally the shortest unique
  abbreviation suffices.


  Because the -nofield option can take the value all as	an argument, alex
  will not recognize a header field called All.	 If you	wish to	use such a
  header field,	you should call	it X-all.

  If a command line contains contradictory arguments then the last value
  specified is used. For example, in the following command, alex only uses
  the options -name fred and -noreplace:

       % alex -name sam	-name fred -replace -noreplace


   1.  This example takes the address from the From field of the current mes-
       sage, and places	it in your alias file with the alias name bob:
	    % alex -field from -alias aliases -name bob

   2.  The following example shows what	happens	if you specify an alias	file
       that does not exist. You	are asked whether you want to create the
       file; enter y to	create it:
	    % alex -field from -name bob -alias	aliases
	    Create alias file "HOME/Mail/aliases"? y

   3.  The next	example	takes addresses	from two fields, From and cc, and
       saves them as the alias sales_team:
	    % alex -field from -field cc -alias	aliases	-name sales_team
