NAME
       mhpath - print full pathnames of nmh messages and folders

SYNOPSIS
       mhpath [+folder] [msgs] [-version] [-help]

DESCRIPTION
       mhpath  expands	and  sorts the message list `msgs' and writes the full
       pathnames of the messages to the standard output separated by newlines.
       If  no  `msgs'  are specified, mhpath outputs the current mail folder's
       pathname instead.  If the only argument is `+', your nmh “Path” is out‐
       put; this can be useful in shell scripts.

       Contrasted  with	 other	nmh commands, a message argument to mhpath may
       often be intended for writing.  Because of this:

       1)  the name “new” has been added to mhpath's list of reserved  message
	   names  (the	others are “first”, “last”, “prev”, “next”, “cur”, and
	   “all”).  The new message is equivalent to  the  message  after  the
	   last	 message  in a folder (and equivalent to 1 in a folder without
	   messages).  The “new” message may not be used as part of a  message
	   range.

       2)  Within a message list, the following designations may refer to mes‐
	   sages that do not exist: a single numeric message name, the	single
	   message  name “cur”, and (obviously) the single message name “new”.
	   All other message designations must refer to at least one  existing
	   message, if the folder contains messages.

       3)  An empty folder is not in itself an error.

       A  message  number less than that of the smallest existing message in a
       folder is treated as if the message already exists.  A  message	number
       greater than that of the highest existing message in a folder causes an
       “out of range” error message to be displayed.

       As part of a range designation that contains messages  that  do	exist,
       message	numbers	 less  than the smallest, or greater than the highest,
       existing message in a folder are ignored.

       Examples: The current folder foo contains messages 3 5 6.  Cur is 4.

	    % mhpath
	    /r/phyl/Mail/foo

	    % mhpath all
	    /r/phyl/Mail/foo/3
	    /r/phyl/Mail/foo/5
	    /r/phyl/Mail/foo/6

	    % mhpath 2001
	    mhpath: message 2001 out of range 1-6

	    % mhpath 1-2001
	    /r/phyl/Mail/foo/3
	    /r/phyl/Mail/foo/5
	    /r/phyl/Mail/foo/6

	    % mhpath new
	    /r/phyl/Mail/foo/7

	    % mhpath last new
	    /r/phyl/Mail/foo/6
	    /r/phyl/Mail/foo/7

	    % mhpath last-new
	    mhpath: bad message list last-new

	    % mhpath cur
	    /r/phyl/Mail/foo/4

	    % mhpath 1-2
	    mhpath: no messages in range 1-2

	    % mhpath first:2
	    /r/phyl/Mail/foo/3
	    /r/phyl/Mail/foo/5

	    % mhpath 1 2
	    /r/phyl/Mail/foo/1
	    /r/phyl/Mail/foo/2

       mhpath is also useful in back-quoted operations:

	    % cd `mhpath +inbox`

	    % echo `mhpath +`
	    /r/phyl/Mail

FILES
       $HOME/.mh_profile	  The user profile

PROFILE COMPONENTS
       Path:		    To determine the user's nmh directory
       Current-Folder:	    To find the default current folder

SEE ALSO
       folder(1)

DEFAULTS
       `+folder' defaults to the current folder
       `msgs' defaults to none

CONTEXT
       None

BUGS
       Like all nmh commands, mhpath  expands  and  sorts  [msgs].   So	 don't
       expect

	    mv `mhpath 501 500`

       to move 501 to 500.  Quite the reverse.	But

	    mv `mhpath 501` `mhpath 500`

       will do the trick.

       Out  of	range message 0 is treated far more severely than large out of
       range message numbers.
