So I am very rusty at scripting, and I am tasked with pushing Mcafee Endpoint Protection 2.1.0 to our Mac systems using Casper.
So I have the default installation script the McAfee administrator gave us, but the script requires user input in order to function (need to type "-i" for a fresh install).
How can I edit the script so it defaults this this option automatically and starts the install?
Heres the install script I am working with:
#!/bin/sh
###getopt for command line arguments.
###Handle the following
### -i install, rpm ivh
### -u upgrade, rpm Uvh )
### -b upgrade but no server info
### -c cloud config path (option for internal usage in bootstrap)
### -h help
PATH=/usr/bin:/bin
umask 022

echo "-i : fresh install "
echo "-u : upgrade install"
echo "-b :Upgrade Agent only , no server info will be updated"

###SUCCESSFUL extraction from the zip depends on it
