folder(1) General Commands Manual folder(1) NAME
folder - set folder or display current folder name (only available within the message handling system, mh) SYNOPSIS
folder [+folder] [msg] [options] 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 com- mand. 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 argu- ment is allowed with this option. This corresponds to the popd operation in the C-shell; see csh(1). The -push and -pop options are mutu- ally 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 num- ber of messages and folders in your Mail directory. This option does not print any information about the current folder. It can be sup- pressed using the -nototal option. The defaults for folder are: +folder defaults to the current folder msg defaults to none -nofast -noheader -nototal -nopack -norecurse DESCRIPTION
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 dis- played. 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. RESTRICTIONS
Do not create folder names that are made up of only digits. PROFILE COMPONENTS
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 EXAMPLES
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. See refile(1) for more details of sub-folders. FILES
