Need help with script
I am attempting to write a script that will capture a runaway java process on our server, which occasionally reaches 99%. I am using the following script.

#!/usr/bin/ksh

jobname="manu_process_watch.sh"
dirname=/opt/manu/mdiap1/scripts
export HOST=`hostname`
filename="${HOST}_`date +%y%m%d`.dat"

ps -aefd -F pid=Process,pcpu=CPU_Use,time=CPU_Time,vsz=Memory,runame=User,args=Command | sort -r +1 | cut -c -130| head -20 > $filename

if test ! -f $dirname/$filename ; then
echo
echo "File $dirname/$filename not found."
echo
fi

process="Java"
command=`grep java $dirname/$filename | cut -f7 -d " "`
pid=`grep java $dirname/$filename | cut -f2 -d " "`
cpupct=`grep java $dirname/$filename | cut -f3 -d " "`
cputime=`grep java $dirname/$filename | cut -f4 -d " "`
numrows=`grep java $dirname/$filename | wc -l`

if [ $cpupct > 90 ] ; then
send an email
fi;
-----------------------------------------------------
This script could potentially yield multiple rows. How can I alter the script so that I only send the email when the cpupct of any of the rows is greater than a certain percentage?

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
