DESCRIPTION


Since the nmh environment is the shell, it is easy to lose track of the current folder
from day to day. When folder is given the -print switch (the default), folder will list
the current folder, the number of messages in it, the range of the messages (low-high),
and the current message within the folder, and will flag extra files if they exist. An
example of this summary is:

inbox+ has 16 messages ( 3- 22); cur= 5.

If a +folder and/or msg are specified, they will become the current folder and/or message.
By comparison, when a +folder argument is given, this corresponds to a “cd” operation in
the shell; when no +folder argument is given, this corresponds roughly to a “pwd”
operation in the shell.

If the specified (or default) folder doesn't exist, the default action is to query the
user as to whether the folder should be created; when standard input is not a tty, the
answer to the query is assumed to be “yes”.

Specifying -create will cause folder to create new folders without any query. (This is
the easy way to create an empty folder for use later.) Specifying -nocreate will cause
folder to exit without creating a non-existant folder. Specifying -all will produce a
summary line for each top-level folder in the user's nmh directory, sorted alphabetically.
(If folder is invoked by a name ending with “s” (e.g. folders), -all is assumed).
Specifying -recurse with -all will also produce a line for all sub-folders. These folders
are all preceded by the read-only folders, which occur as “atr-cur-” entries in the user's
nmh context. For example:

FOLDER # MESSAGES RANGE CUR (OTHERS)
/var/work/folder has 35 messages ( 1- 35); cur=23.
/usr/bugs/Mail has 82 messages ( 1-108); cur=82.
ff has no messages.
inbox+ has 16 messages ( 3- 22); cur= 5.
mh has 76 messages (15- 76); cur=70.
notes has 2 messages ( 1- 2); cur= 1.
ucom has 124 messages ( 1-124); cur= 6; (others).
TOTAL = 339 messages in 7 folders

The “+” after inbox indicates that it is the current folder. The “(others)” indicates
that the folder ucom has files which aren't messages. These files may either be
sub-folders, or files that don't belong under the nmh file naming scheme.

The header is output if either a -all or a -header switch is specified. It is suppressed
by -noheader.

The folder and message totals are output if either a -all or a -total switch is specified.
It is suppressed by -nototal.

If -fast is given, only the folder name (or names in the case of -all) will be listed.
(This is faster because the folders need not be read.)

If a +folder is given along with the -all switch, folder will, in addition to setting the
current folder, list the top-level subfolders for the current folder (with -norecurse) or
list all sub-folders under the current folder recursively (with -recurse).

If msg is supplied, together with +folder or without -all, it will become the current
message of +folder (if it had been supplied) or the current folder.

The -recurse switch lists each folder recursively, so use of this option effectively
defeats the speed enhancement of the -fast option, since each folder must be searched for
subfolders. Nevertheless, the combination of these options is useful.

Compacting a Folder
The -pack switch will compress the message names in the designated folders, removing holes
in message numbering. The -verbose switch directs folder to tell the user the general
actions that it is taking to compress the folder.

The Folder Stack
The -push switch directs folder to push the current folder onto the folder-stack, and make
the +folder argument the current folder. If +folder is not given, the current folder and
the top of the folder-stack are exchanged. This corresponds to the “pushd” operation in
the shell.

The -pop switch directs folder to discard the top of the folder-stack, after setting the
current folder to that value. No +folder argument is allowed. This corresponds to the
“popd” operation in the shell. The -push switch and the -pop switch are mutually
exclusive: the last occurrence of either one overrides any previous occurrence of the
other. Both of these switches also set -list by default.

The -list switch directs folder to list the contents of the folder-stack. No +folder
argument is allowed. After a successful -push or -pop, the -list action is taken, unless
a -nolist switch follows them on the command line. This corresponds to the “dirs”
operation in the shell. The -push, -pop, and -list switches turn off -print.
