loops (the same message cycling through a sequence of machines without
ever getting to its intended destination).
–r address
Passes the given address to network mail software. If this option is present,
it disables all input mode commands. Again, this option is not intended for
most users.
–s subject
Uses the given subject string in the Subject heading line of the message. If
the subject contains spaces or tab characters, the string should be
enclosed in double quotes or single quotes. If you specify this option on the
command line, mailx does not prompt you to enter a subject line when you
type in the text of the message. The subject accepts at most
LINE_MAX-10(2038) bytes. Any subjects longer than that will be truncated
at 2038.
–U Converts the address from UNIX-to-UNIX Copy Program (UUCP) style to
Internet Protocol standards. This option overrides the effect of the conv
variable.
This option is not supported.
You can use these options for both sending and reading messages:
–i Ignores interrupts (for example, from pressing or ).
–n Does not initialize your mailx session from the system’s /etc/mailx.rc file.
General Overview
This section describes the default behavior of mailx.
The simplest command to send a message is:
mailx address address address ...
where each address names someone who is to receive the message. The simplest
kind of address is the login name of someone else who uses your shell.
You can also send messages as input to commands. To do this, use an address
that consists of a pipe symbol (|) followed by a command line that invokes the
appropriate command; enclose this whole address in single quotes. For example:
mailx ROBIN ’|cat >save’
mails a message to ROBIN and also copies the message into a file called save.
mailx
After you type in the command to send a message, mailx asks you to enter the
subject of the message (a brief description of what the message is about), and then
lets you type in the text of the message. This brief description can be up to 256
characters long. Your message can consist of any number of lines, and may include
blank lines. When you finish entering the message, type a line consisting only of a
tilde (~), followed by a period (.); then press the enter key. This tells mailx that the
message is ready to be sent.
mailx puts the completed message into a file called the recipient’s system mailbox.
The message stays in the system mailbox until the recipient asks to read the
message. At that point, the message is obtained from the system mailbox and
displayed on the recipient’s workstation. The message is then saved in the
recipient’s personal mailbox. Since this is usually a file named mbox in the
