14 folders is equivalent to folder -all

17 Since the nmh environment is the shell, it is easy to lose track of the
18 current folder from day to day. When folder is given the -print switch
19 (the default), folder will list the current folder, the number of mes‐
20 sages in it, the range of the messages (low-high), and the current mes‐
21 sage within the folder, and will flag extra files if they exist. An
22 example of this summary is:
23
24 inbox+ has 16 messages ( 3- 22); cur= 5.
25
26 If a +folder and/or msg are specified, they will become the current
27 folder and/or message. By comparison, when a +folder argument is
28 given, this corresponds to a “cd” operation in the shell; when no
29 +folder argument is given, this corresponds roughly to a “pwd” opera‐
30 tion in the shell.
31
32 If the specified (or default) folder doesn't exist, the default action
33 is to query the user as to whether the folder should be created; when
34 standard input is not a tty, the answer to the query is assumed to be
35 “yes”.
36
37 Specifying -create will cause folder to create new folders without any
38 query. (This is the easy way to create an empty folder for use later.)
39 Specifying -nocreate will cause folder to exit without creating a non-
40 existant folder.
41
42
43 Multiple Folders
44 Specifying -all will produce a summary line for each top-level folder
45 in the user's nmh directory, sorted alphabetically. (If folder is
46 invoked by a name ending with “s” (e.g. folders), -all is assumed).
47 Specifying -recurse with -all will also produce a line for all sub-
48 folders. These folders are all preceded by the read-only folders,
49 which occur as “atr-cur-” entries in the user's nmh context. For exam‐
50 ple:
51
52 FOLDER # MESSAGES RANGE CUR (OTHERS)
53 /var/work/folder has 35 messages ( 1- 35); cur=23.
54 /usr/bugs/Mail has 82 messages ( 1-108); cur=82.
55 ff has no messages.
56 inbox+ has 16 messages ( 3- 22); cur= 5.
57 mh has 76 messages (15- 76); cur=70.
58 notes has 2 messages ( 1- 2); cur= 1.
59 ucom has 124 messages ( 1-124); cur= 6; (others).
60
61 TOTAL = 339 messages in 7 folders
62
63 The “+” after inbox indicates that it is the current folder. The
64 “(others)” indicates that the folder ucom has files which aren't mes‐
65 sages. These files may either be sub-folders, or files that don't
66 belong under the nmh file naming scheme.
67
68 The header is output if either a -all or a -header switch is specified.
69 It is suppressed by -noheader.
70
71 The folder and message totals are output if either a -all or a -total
72 switch is specified. It is suppressed by -nototal.
73
74 If -fast is given, only the folder name (or names in the case of -all)
75 will be listed. (This is faster because the folders need not be read.)
76
77 If a +folder is given along with the -all switch, folder will, in addi‐
78 tion to setting the current folder, list the top-level subfolders for
79 the current folder (with -norecurse) or list all sub-folders under the
80 current folder recursively (with -recurse). In this case, if a msg is
81 also supplied, it will become the current message of +folder.
82
83 The -recurse switch lists each folder recursively, so use of this
84 option effectively defeats the speed enhancement of the -fast option,
85 since each folder must be searched for subfolders. Nevertheless, the
86 combination of these options is useful.
87
88 Compacting a Folder
89 The -pack switch will compress the message names in the designated
90 folders, removing holes in message numbering. The -verbose switch
91 directs folder to tell the user the general actions that it is taking
92 to compress the folder.
93
94 The Folder Stack
95 The -push switch directs folder to push the current folder onto the
96 folder-stack, and make the +folder argument the current folder. If
97 +folder is not given, the current folder and the top of the
98 folder-stack are exchanged. This corresponds to the “pushd” operation
99 in the shell.
100
101 The -pop switch directs folder to discard the top of the folder-stack,
102 after setting the current folder to that value. No +folder argument is
103 allowed. This corresponds to the “popd” operation in the shell. The
104 -push switch and the -pop switch are mutually exclusive: the last
105 occurrence of either one overrides any previous occurrence of the
106 other. Both of these switches also set -list by default.
107
108 The -list switch directs folder to list the contents of the
109 folder-stack. No +folder argument is allowed. After a successful
110 -push or -pop, the -list action is taken, unless a -nolist switch fol‐
111 lows them on the command line. This corresponds to the “dirs” opera‐
112 tion in the shell. The -push, -pop, and -list switches turn off
113 -print.

151 whether to create a non-existant folder) after -create or -nocreate is
