rmf
RMF(1) [nmh-1.5] RMF(1)NAME
rmf - remove an nmh folder
SYNOPSIS
rmf [+folder] [-interactive | -nointeractive] [-version] [-help]
DESCRIPTION
Rmf removes all of the messages (files) within the specified (or default) folder, and then removes the folder (directory) itself.
If there are any files within the folder which are not a part of nmh, they will not be removed, and an error will be produced. If the
folder is given explicitly or the -nointeractive option is given, then the folder will be removed without confirmation. Otherwise, the
user will be asked for confirmation. If rmf can't find the current folder, for some reason, the folder to be removed defaults to `+inbox'
(unless overridden by user's profile entry "Inbox") with confirmation.
If the folder being removed is a subfolder, the parent folder will become the new current folder, and rmf will produce a message telling
the user this has happened. This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list
and returning to the current folder from which the list was extracted.
If rmf s used on a read-only folder, it will delete all the (private) sequences (i.e., "atr-seq-folder" entries) for this folder from your
context without affecting the folder itself.
Rmf irreversibly deletes messages that don't have other links, so use it with caution.
FILES
$HOME/.mh_profile The user profile
PROFILE COMPONENTS
Path: To determine the user's nmh directory
Current-Folder: To find the default current folder
Inbox: To find the default inbox
SEE ALSO rmm(1)DEFAULTS
`+folder' defaults to the current folder, usually with confirmation
`-interactive' if +folder' not given, `-nointeractive' otherwise
CONTEXT
Rmf will set the current folder to the parent folder if a subfolder is removed; or if the current folder is removed, it will make "inbox"
current. Otherwise, it doesn't change the current folder or message.
BUGS
Although intuitively one would suspect that rmf works recursively, it does not. Hence if you have a sub-folder within a folder, in order
to rmf the parent, you must first rmf each of the children.
