Thank you very much methyl, kodak.

pcmon is a script that will send information to monitoring system.

Could you please clarify somne of dobuts:

1. What happen if I not close case statement?

2. How could I avoid so many if then loops and make my script more optimize?

3. As you said "The script is mostly a case statement but is badlly laid out ", pls let me know can make this one is as good as compared to the old one?

Thanks,
Gobinathan.S

Also, Is it possible to use the statement as below or suggest me the way to go in a good way

Instead of using like:

Code:

case $4 in "Too many open files") 
STATUS=0 
if [ $value -eq 11 ] || [ $value -eq 15 ] then 
if [ $CMD_OUTPUT -gt 500 ]
then
if [ $extension -lt 12 ]
then
STATUS=1 
fi
fi
fi

Can I use:

Code:

if (( ( $value -eq 11 || $value -eq 15 ) && ( $CMD_OUTPUT -gt 500 ) && ( $extension -lt 12 ) )) then;
STATUS=1

Is this a good way of doing it, will it optimize my requirement.

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.
