folders |
is equivalent to folder −all |
Since the mmh 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 mmh 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 mmh 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 mh file naming scheme.
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.
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 −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.

There is no way to restore the default behavior (to ask the user whether to create a non-existant folder) after −create or −nocreate is given.
