Registered User

Ok everyone, I am back. My problem this time is the elm -s in the 2nd if loop is not working. I cannot get it to mail the message to me when I am offline. Here is my code:

Code:

# 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 $TIME << EOF
if [ `who | grep -c "$LOGNAME"` -gt 0 ]; then
who | cut -c1-20 | grep $LOGNAME | cut -c12-20 > ~/tmp
while read inputline
do
        write $LOGNAME \$inputline < ~/Msgs/message.$$ > /dev/null 2>&1
done < ~/tmp
exit
fi
if [ `who | grep -c "$LOGNAME"` -eq 0 ]; then
elm -s $LOGNAME < ~/Msgs/message.$$
exit
fi
rm -r ~/Msgs
rm -r ~/tmp
exit 0
EOF

Can anyone see what might be the problem? I appreciate all the help here. I will clean up this script with sed and awk on the next assignment. We are in the process of learning both now.

DROP TEXT SEARCH 
TEMPLATE(7)					   SQL Commands 				      DROP TEXT SEARCH TEMPLATE(7)

NAME

       DROP TEXT SEARCH TEMPLATE - remove a text search template

SYNOPSIS

       DROP TEXT SEARCH TEMPLATE [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TEXT SEARCH TEMPLATE drops an existing text search template. You must be a superuser to use this command.

PARAMETERS

       IF EXISTS
	      Do not throw an error if the text search template does not exist.  A notice is issued in this case.

       name   The name (optionally schema-qualified) of an existing text search template.

       CASCADE
	      Automatically drop objects that depend on the text search template.

       RESTRICT
	      Refuse to drop the text search template if any objects depend on it.  This is the default.

EXAMPLES

       Remove the text search template thesaurus:

       DROP TEXT SEARCH TEMPLATE thesaurus;

       This command will not succeed if there are any existing text search dictionaries that use the template. Add CASCADE to drop such dictionar-
       ies along with the template.

COMPATIBILITY

       There is no DROP TEXT SEARCH TEMPLATE statement in the SQL standard.
