mailx
recipient’s home directory, we use the name mbox to represent the personal
mailbox and mailbox for a system mailbox.
The simplest way to read incoming messages is to type the command mailx (with
no addresses on the command line). This starts an interactive session in which
mailx lets you read your mail and perform other operations. For example, you can
display new messages, delete old ones, reply to messages, or forward them to
someone else, and so on. When you are performing operations in this way, you are
in command mode. When you are typing in the text of a message, you are in input
mode.
A message consists of a sequence of header lines, followed by the body of the
message. The header lines tell who sent the message, the time and date that the
message was sent, the subject of the message, and so on. mailx automatically
creates header lines. Some of the common header lines are:
Cc: name name ...
Stands for “carbon copies”. This indicates that copies of this message are
to be sent to the specified recipients. The names of these recipients appear
in the header lines of everyone receiving the message.
Bcc: name name ...
Stands for “blind carbon copies”. This is similar to Cc:, but the names of
people receiving carbon copies do not appear in the header lines of the
message. Recipients do not know that these people received a copy of the
message.
Subject: text
Gives the subject of the message.
To: name name ...
Gives the names of people who were sent the message directly.
All messages are in one of the following states:
deleted
You used a delete, dp, or dt command to delete the message. When mailx
quits, messages in this state are deleted.
new The message is in the system mailbox and you have not yet read it or
otherwise changed its state. When mailx quits, messages in this state are
kept in your system mailbox.
preserved
You used a preserve command on the message. When mailx quits,
messages in this state are kept in their current locations.
read You used one of the following commands on the message:
~F copy Print type
~f mbox print undelete
~M next top
~m pipe Type
or you used delete , dp, or dt on the preceding message and the autoprint
variable was set. When mailx quits and you are in your system mailbox,
read messages are kept in your personal mailbox—unless the hold
variable is set, in which case, read messages are kept in your system
mailbox. If you are in your personal or a secondary mailbox when mailx
quits, read messages are kept in their current location.
saved You used a save or write command on the message. If the current mailbox
