Help with an install script

Hello all.

I have a script I have written which runs a silent install of Mcafee AV and ePO for Mac OS X.

The issue I am wondering about is what happens when the script launches the installers.

The script is fairly simple, and just invokes the shell installer for each app:

Code:

#! /bin/sh

# script to install Mcafee VirusScan and ePolicy Orchestrator 3.6

# cd to temp install directory

cd /tmp/Mcafee_Install/

# Launch AV installer

installer -pkg VirusScan.pkg -target /

# Sleep while AV installer completes install

sleep 60

# Next installs ePolicy Orchestrator

./cmdinstall 10.44.112.40:82

# Sleep while ePO installer completes.

sleep 120

# Reboot to complete install.

reboot

You'll notice that I have told the script to sleep after launching the installer for each app. My question is: "Is this necessary?"

My thinking was that once the script has launched the installer, that's a separate process and as far as I am aware, my script would simply continue with the second install immediately. I don't want both apps installing at the same time, or the system rebooting halfway through the second install, so I told the script to sleep for a moment, to give the installs a chance to complete.

Am I being silly here? Are the sleep commands necessary? Will the script wait for the install to complete before launching the next install, or rebooting in the case of the second install?

Any thoughts?

Cheers

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
