where from is the name of the person the message is from, and
subject is the subject of the message, if present. If the message is
from you, the from portion will read ``To user'', where `user' is the
user the message was sent to. This happens when you receive a copy of a
letter you sent.
If a folder is specified, the program reads that folder
rather than the default mailbox. If the argument is a
username then frm looks in that user's mailbox, provided you
have permission to read it.
A folder can be specified with the same notation as
when invoking the Elm mailer (e.g., =folder).
Frm invoked as nfrm is identical to invoking ``frm -s new''.
OPTIONS
The frm program has the following options:
-h
Print a brief help message summarizing the options.
-M
Magic mode - treat all folders as if they were the spool folder
(lock, update Status: headers, etc.).
-n
Number the messages using the same numbering scheme that, for
example, readmsg will understand.
-Q
Very quiet mode. Only error messages are produced. This option is useful
in shell scripts, where only the success or failure of the program is
important, and output is not desired.
-q
Quiet mode. Output only a one-line summary for each mailbox or folder
specified.
-S
Summarize the number of messages by message status in each mailbox or
folder. If you want just a summary line, use this in conjunction with the
-q option.
-s status
Only display headers from messages with the given status. `status' is one
of "new", "unread", "old" (same as "unread"), or "read". The -s
option can be specified multiple times to print header information from,
for example, only new and unread messages. It is sufficient to specify
only the first letter of the status.
-t
Tidy mode. If the from field is long enough to displace the
subject field from its natural start column, move the subject
down onto the next line.
-v
Verbose mode. Print a descriptive header before listing the contents of
each mailbox or folder.
EXIT STATUS
Frm
returns a zero status ("true") if messages matching `status' are present.
Frm
returns 1 if no messages matching `status' are present, but there are some
messages, returns 2 if there are no messages at all, or returns 3 if an
error occurred. If multiple mailboxes or folders are specified, the exit
status only applies to the last one examined. This can be used in scripts
to determine what kind of mail a user has.
EXAMPLES
Some example uses:
$ frm
will display header information from all the messages in your mailbox, or
``You have no mail.'' if there are no messages in your incoming mailbox.
$ frm -s new
will display header information from all new messages in your mailbox, or
``You have no new mail.'' Note the slightly different diagnostic.
$ frm -s new -s unread guest
assuming you have the proper file permissions to read guest's mail, will
print out header information from all new and unread messages in guest's
incoming mailbox. If there are no messages, frm will print ``guest
has no mail.''
$ frm -q -S
will print only a one line summary of how many read, unread, and read
messages are in your incoming mailbox. For example, ``You have 2 new
messages, 3 unread messages, 23 read messages.''
