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
folder. 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 contains. 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
-nofast
-noheader
-nototal
-nopack
-norecurse
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 use.
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
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. % folder +test
test+ has 2 messages ( 1- 2);
cur= 2. The next example shows the display produced by
using the -all option to folder:
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. The next example shows how to use
folder to create an empty folder: % folder +test
Create folder "$HOME/Mail/test"? y
test+ has no messages. You can also use
folder to create an empty sub-folder within an
existing folder. The following example shows how
you can create a sub-folder in the folder +test: %
folder +test/testtwo Create folder
"$HOME/Mail/test/testwo"? y
test/testtwo+ has no messages.
