OK, after reading the linked lesson (Lesson 13: Positional Parameters), I have written a test program. This program is called "positional_parameters":
Code:
set -vx

set

echo "Positional Parameters"

# The following commented lines do not work.
# Is it because I am using the Bourne Shell?
# if["$1"!=""];
# then echo "Positional parameter 1 contains something."
# else echo "Positional parameter 1 is empty."
# fi

# if[ $# -gt 0 ]; then
# echo "Your command line contains $# arguments"
# else echo "Your command line contains no arguments"
# fi

echo '$0 = ' $0
echo '$1 = ' $1
echo '$2 = ' $2
echo '$3 = ' $3

banner $1 $2 $3
banner "$1 $2 $3"

banner "$*"
banner "$@"

# mailtolist=someName@someDomain.com

mailtolist=someName@someDomain.com

mail mailtolist < testing

set +vx

The following are the contents of the "testing" file:
Code:
banner testing
banner 1 2 3 4

I am getting the following error when I run the positional_parameters program:
Code:
mailtolist... User unknown

Am I not initializing it correctly?

Is it possible for the mailtolist variable to contain more than one e-mail address?

I would like to try to invoke the positional_parameters program from the command line and send the contents of my testing file to my e-mail address.
Would this be the correct command?
Code:
$> positional_parameters testing

Do I need to export mailtolist?
Do I need to use command substitution to test it?

I appreciate the feedback. I am enjoying what I am learning so far.

Thank you,
Eric

libssh2_banner_set

libssh2_banner_set(3)						  libssh2 manual					     libssh2_banner_set(3)

NAME

       libssh2_banner_set - set the SSH prococol banner for the local client

SYNOPSIS

       #include <libssh2.h>

       int libssh2_banner_set(LIBSSH2_SESSION *session, const char *banner);

DESCRIPTION

       This function is DEPRECATED. Use libssh2_session_banner_set(3) instead!

       session - Session instance as returned by libssh2_session_init_ex(3)

       banner - A pointer to a user defined banner

       Set the banner that will be sent to the remote host when the SSH session is started with libssh2_session_handshake(3)
	 This is optional; a banner corresponding to the protocol and libssh2 version will be sent by default.

RETURN VALUE

       Return 0 on success or negative on failure.  It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a
       negative number, it isn't really a failure per se.

AVAILABILITY

       Marked as deprecated since 1.4.0

ERRORS

       LIBSSH2_ERROR_ALLOC -  An internal memory allocation call failed.

SEE ALSO
