11 \fIMhpath\fR expands and sorts the message list `msgs' and writes
12 the full pathnames of the messages to the standard output
13 separated by newlines.
14 If no `msgs' are specified,
15 \fImhpath\fR outputs the folder pathname instead.
16 If the only argument is `+', your MH \fIPath\fR is output;
17 this can be useful is shell scripts.

19 Contrasted with other MH commands, a message argument to \fImhpath\fR
20 may often be intended for \fIwriting\fR.
21 Because of this:
22 .sp
23 1) the name \*(lqnew\*(rq has been added to \fImhpath\fR's list of
24 reserved message names
25 (the others are \*(lqfirst\*(rq, \*(lqlast\*(rq, \*(lqprev\*(rq,
26 \*(lqnext\*(rq, \*(lqcur\*(rq, and \*(lqall\*(rq).
27 The new message is equivalent to the message after the
28 last message in a folder
29 (and equivalent to 1 in a folder without messages).
30 The \*(lqnew\*(rq message may not be used as part of a message range.
31 .sp
32 2) Within a message list,
33 the following designations may refer to messages that do not exist:
34 a single numeric message name,
35 the single message name \*(lqcur\*(rq,
36 and (obviously) the single message name \*(lqnew\*(rq.
37 All other message designations must refer to at least one existing message.
38 .sp
39 3) An empty folder is not in itself an error.
40
41 Message numbers greater than the highest existing message in a folder as
42 part of a range designation are replaced with the next free message number.
43
44 Examples: The current folder foo contains messages 3 5 6.
45 Cur is 4.

91 \fIMHpath\fR is also useful in back\-quoted operations:
92
93 .nf
94 .in +.5i
95 % cd `mhpath +inbox`
96
97 % echo `mhpath +`
98 /r/phyl/Mail

116 Like all MH commands, \fImhpath\fR expands and sorts \%[msgs].
117 So don't expect
118
119 .ti +.5i
120 mv `mhpath 501 500`
121
122 to move 501 to 500.
123 Quite the reverse. But
124
125 .ti +.5i
126 mv `mhpath 501` `mhpath 500`
127
128 will do the trick.
129
130 Out of range message 0 is treated far more severely than large out of
131 range message numbers.
