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.
FOLDER # MESSAGES RANGE CUR (OTHERS) /var/work/folder has 35 messages ( 1- 35); cur=23. /usr/bugs/Mail has 82 messages ( 1-108); cur=82. ff has no messages. 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 -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 shell. 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 shell. The -push, -pop, and -list switches turn off -print.
