Описание (Description)
The mailx utility provides a message sending and receiving
facility. It has two major modes, selected by the options used:
Send Mode and Receive Mode.
On systems that do not support the User Portability Utilities
option, an application using mailx shall have the ability to send
messages in an unspecified manner (Send Mode). Unless the first
character of one or more lines is <tilde> ('~'), all characters
in the input message shall appear in the delivered message, but
additional characters may be inserted in the message before it is
retrieved.
On systems supporting the User Portability Utilities option,
mail-receiving capabilities and other interactive features,
Receive Mode, described below, also shall be enabled.
Send Mode
Send Mode can be used by applications or users to send messages
from the text in standard input.
Receive Mode
Receive Mode is more oriented towards interactive users. Mail can
be read and sent in this interactive mode.
When reading mail, mailx provides commands to facilitate saving,
deleting, and responding to messages. When sending mail, mailx
allows editing, reviewing, and other modification of the message
as it is entered.
Incoming mail shall be stored in one or more unspecified
locations for each user, collectively called the system mailbox
for that user. When mailx is invoked in Receive Mode, the system
mailbox shall be the default place to find new mail. As messages
are read, they shall be marked to be moved to a secondary file
for storage, unless specific action is taken. This secondary file
is called the mbox and is normally located in the directory
referred to by the HOME environment variable (see MBOX in the
ENVIRONMENT VARIABLES section for a description of this file).
Messages shall remain in this file until explicitly removed. When
the -f option is used to read mail messages from secondary files,
messages shall be retained in those files unless specifically
removed. All three of these locations—system mailbox, mbox, and
secondary file—are referred to in this section as simply
``mailboxes'', unless more specific identification is required.
