800 kb process_4
700 kb process_5
100 kb process_6

i want to write a script which suppose to show the processes with the desired parameter

for example if the user want the processes with memory usage of 600kb and greater the user should pass 600 as a parameter(which is x) and this script suppose to show the following :

process_2
process_3
process_4
process_5

Note: my command is : ps -efo somthing | grep somthing | grep somthing
it is a very very long command which i can't remember right now XD

so the guys helped me with the x thing and it was working fine to me
that was the porpuse of the x

now i have ran the shutdown_script by using for loop on each proccess came out from the final command which is

process_2
process_3
process_4
process_5

(the ones >=600 kb)

Note: final command is : ps -efo somthing | grep somthing | grep somthing | awk -vx=$x '$1>=x{print $NF}'

by running the following

Code:

echo "Enter value: " 
read x 
 
for i in `my_command| awk -vx=$x '$1>=x{print $NF}'`;do
 
shutdown_script $i
 
done

so the processes was shutted down successfully but i had another problem

i want to do another loop that running another script which is

(start_script) on each process i did shutdown but the problem is the process does not exist by running "ps -efo" since it was killed

so i came up with temp file or variable or whatever so the temp will save the processes that i did shutdown by save them in a temp file/variable before shutting them down, and then reuse them again in the starting loop using (start_script)

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

 *

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
