folder - set folder or display current folder name (only available within
the message handling system, mh)
folder [+folder] [msg] [options]
Displays information on all the folders in your Mail directory. The
folders are listed alphabetically, with a line of information given for
each folder. This is identical to the display produced by the folders
command. See folders(1).
Lists only the name of the current folder, with no additional
information. This is faster because the folders need not be read.
Displays a header produced by the system, in addition to the
information about the current file. This header is identical to the one
that appears at the top of the listing produced by folder -all or by
folders. The header can be suppressed by using the -noheader option.
Prints a list of the valid options to this command.
Lists the contents of the folder-stack. No +folder argument is allowed
with this option. The contents of the folder-stack are listed
automatically when the -pop or -push option is used. This corresponds
to the dirs operation in the C-shell.
Re-numbers messages in the folder. Messages are re-numbered
sequentially, and any gaps in the numbering are removed. The default
operation is -nopack, which does not change the numbering in the
Discards the top of the folder-stack, after setting the current folder
to that value. No +folder argument is allowed with this option. This
corresponds to the popd operation in the C-shell; see csh(1). The -push
and -pop options are mutually exclusive: the last occurrence of either
one overrides any previous occurrence of the other.
Pushes the current folder onto the folder-stack, and makes the +folder
argument into 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 C-shell; see csh(1). The -push switch
and the -pop switch are mutually exclusive: the last occurrence of
either one overrides any previous occurrence of the other.
Lists each folder recursively. Information on the current folder is
displayed, followed by information on any sub-folders which it
Displays only the total number of messages and folders in your Mail
directory. This option does not print any information about the current
folder. It can be suppressed using the -nototal option.
The defaults for folder are:
+folder defaults to the current folder
msg defaults to none
The folder command lets you set the current folder, or display information
about it. It can also be used to manage the folder stack.
If you use the folder command without a +folder argument, information about
the current folder is displayed on the screen. If you use folder with the
+folder argument, the named folder is set to be the current folder.
Information about the named folder is also displayed on the screen.
If you use folder with the msg argument, it will set the specified message
to be current. Information on the current folder is also displayed. You can
use both the +folder and msg arguments together in one command.
If you specify a +folder that does not exist, you are asked whether you
want to create it. This is a good way to create an empty folder for later
The display is identical whether you set the folder or display the contents
of the current folder. The following example shows the type of display that
is produced. The display lists the current folder, the number of messages
in it, the range of the messages (low-high), and the current message within
the folder. It also flags extra files if they exist.
inbox+ has 16 messages ( 3- 22); cur= 15.
Do not create folder names that are made up of only digits.
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
lsproc: Program to list the contents of a folder
1. The following example shows how folder can be used to change the
current folder to +test, and display information on that folder. The
plus sign (+) next to test indicates that it is now the current
% folder +test
test+ has 2 messages ( 1- 2); cur= 2.
2. The next example shows the display produced by using the -all option
Folder # of messages ( range ); cur msg (other files)
V2.3 has 3 messages ( 1- 3).
adrian has 20 messages ( 1- 20); cur= 2.
brian has 16 messages ( 1- 16).
chris has 12 messages ( 1- 12).
copylog has 242 messages ( 1- 242); cur= 225.
inbox+ has 73 messages ( 1- 127); cur= 127.
int has 4 messages ( 1- 4); cur= 2 (others).
jack has 17 messages ( 1- 17); cur= 17.
TOTAL= 387 messages in 8 folders.
This display is identical to that produced by the folders command. See
folders(1) for an explanation of this display.
3. The next example shows how to use folder to create an empty folder:
% folder +test
Create folder "$HOME/Mail/test"? y
test+ has no messages.
4. You can also use folder to create an empty sub-folder within an
existing folder. The following example shows how you can create a
sub-folder in the folder +test:
% folder +test/testtwo
Create folder "$HOME/Mail/test/testwo"? y
test/testtwo+ has no messages.
