Registered User

Got it! Here is the correct code. Still needs some efficiency put into it but it will work for the time being.

Code:

#!/usr/dt/bin/dtksh
# Alertme.p1 program, version 0.7
# Author - Clint Sharp
# This program is interactive and will alert the user
# if they are online at more than one terminal. It will also mail the
# user at the mail address associated with the user id.
mkdir ~/Msgs
echo "\nEnter your reminder message.
When finished, enter a period (.) at
the beginning of a line and press <ENTER>.
(Or press Ctrl-C to exit the script)\n"
while :
do
    read MESSAGE
    if [ "$MESSAGE" = "." ]
    then
        break
    else
        echo $MESSAGE >> ~/Msgs/message.$$
    fi
done
echo "\nEnter the time and day you want to
receive the message, for example:
0815am Jun 14
8:15am Jun 14
now + 1 day
5 pm Friday
8:15am 6/14/2011
Then press <ENTER>\n"
read TIME
echo "\nAt $TIME mail or write $LOGNAME ~/Msgs/message.$$\n"
at -k $TIME << EOF
if ! who | grep ^$LOGNAME > /dev/null; then
mail $LOGNAME < ~/Msgs/message.$$
fi
if [ `who | grep -c "$LOGNAME"` -gt 0 ]; then
who | cut -c1-20 | grep $LOGNAME | cut -c12-20 | while read LINE
#while read inputline
do
    write $LOGNAME \$LINE < ~/Msgs/message.$$ > /dev/null 2>&1
done
fi
rm -r ~/Msgs

exit 0
EOF

profile(4)                                                         File Formats                                                         profile(4)

NAME

       profile - setting up an environment for user at login time

SYNOPSIS

       /etc/profile

       $HOME/.profile

DESCRIPTION

       All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence.

       /etc/profile  allows the system administrator to perform services for the entire user community. Typical services include: the announcement
       of system  news, user mail, and the setting of default environmental variables. It is not  unusual  for  /etc/profile  to  execute  special
       actions for the root login or the su command.

       The  file  $HOME/.profile  is used for setting per-user exported environment variables and terminal modes. The following example is typical
       (except for the comments):

              # Make some environment variables global
              export MAIL PATH TERM
              # Set file creation mask
              umask 022
              # Tell me when new mail comes in
              MAIL=/var/mail/$LOGNAME
              # Add my /usr/usr/bin directory to the shell search sequence
              PATH=$PATH:$HOME/bin
              # Set terminal type
              TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid
              while :
              do
                      if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ]
                   then break
                      elif [ -f /usr/share/lib/terminfo/?/$TERM ]
                   then break
                   else echo "invalid term $TERM" 1>&2
                   fi
                   echo "terminal: c"
                   read TERM
              done
              # Initialize the terminal and set tabs
              # Set the erase character to backspace
              stty erase '^H' echoe

FILES

       $HOME/.profile          user-specific environment

       /etc/profile            system-wide environment

NOTES

       Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better  for  serving  all  but  the  most
       global needs.
