mailx
Description
Options
mailx helps you read electronic mail messages. It can also send messages to
users on your system, but it has no built-in facilities for sending messages to other
systems.
The command line:
mailx [options] user user user ...
sends a mail message to the given users. If you do not specify any users on the
command line, mailx lets you read incoming mail interactively. For more
information, see sendmail.
In a doublebyte locale, aliases, variables, and addresses can contain doublebyte
characters.

You can use the following options when reading messages:
–e Checks to see if you have any messages waiting to be read. With this
option, nothing is displayed. If you have waiting messages, mailx exits with
a successful status return; otherwise, mailx exits with a failure return.
–f filename
Looks for messages in the specified file instead of in your current mailbox.
If you do not specify filename, mailx reads messages from $HOME/mbox.
–H Displays only the header summary of a message.
–N Does not display the header summary of messages.
–u user
Looks for messages in the system mailbox of the specified user. This works
only if you have read permission on the user’s system mailbox.
You can use the following options only when sending messages:
–F Records your message in a file with the same name as the first user
specified on the command line. This option overrides the record variable, if
it has been set.
–h number
Indicates how many “hops” a message has already made from one
machine to another (in a network of machines). This option is not intended
for most users; network mail software uses the option to prevent infinite
