Unix Script to find and kill a process with high memory utilization

Hi Unix Gurus i am somewhat new to unix scripting so need your help to
create a script as below.

# This script would find the process consuming memory beyond a certain #limit. if the meemory consumption is more than 100% for a period of 1
# minute for the specific process. the script would kill the process

top -n 1 -u user | grep ABC | awk '{print $1" "$10}' > pid_mem

#Example pid_mem where $1 is process id and $10 is %memory consumed
# file contains the pid and memory % as below example
12258 21.6
12298 51.5
19207 107.5
#read the text for file and determine the pid for process with %mem > 100
# example pid = 19207
#if exist # then iterate for sometime for the same process id to determine if the memory spike comes down for example

count=0
while (count <=5) {
top -n 1 -u user | grep $pid
if ($10 > 100)
sleep 10
if (count =5)
then if ($10 >100)
kill -9 $pid
echo "Memory is more than 100 so process killed" | mailx -r %date -s 'memory > 90%' abc@z.com
endif
endif
count =count + 1
endif
}

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
