folders is equivalent to folder -all
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,
|

/var/work/folder |

( 1− 35); |
cur=23. | |

( 1−108); |
cur=82. | |
|

|
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’). In this case, if a ’msg’ is also supplied, it will become the current message of ’+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 CShell.
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 CShell. 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 CShell. The ’−push’, ’−pop’, and ’−list’ switches turn off ’−print’. ^$HOME/.mh_profile~^The user profile ^Path:~^To determine the user’s nmh directory ^Current−Folder:~^To find the default current folder ^Folder−Protect:~^To set mode when creating a new folder ^Folder−Stack:~^To determine the folder stack refile(1), mhpath(1) ’+folder’ defaults to the current folder ’msg’ defaults to none ’−nofast’ ’−noheader’ ’−nototal’ ’−nopack’ ’−norecurse’ ’−noverbose’ ’−print’ is the default if no ’−list’, ’−push’, or ’−pop’ is specified ’−list’ is the default if ’−push’, or ’−pop’ is specified If ’+folder’ and/or ’msg’ are given, they will become the current folder and/or message. 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.
