Script - BE patching script

If you've read the previous blogs for the u10 BE patching process you'll know it is a bit long winded - so I've tried my hand a little bash scripting. It has been tried out on a test box and it works.....

The error handling isn't exactly what I want and therefore the script will be subject to change.

u10 upgrade script (updater)

#!/usr/bin/ksh
# Bash script for Solaris patching
# To be stored in /usr/local/sbin for Systems Administrator

# Prior to running script make sure enough free space is available on the target server.
# Enough space is required for:
# Patch bundle - 2Gb
# Extracted patch bundle - 4Gb
# BE patches - 20Mb
# New boot environment - 6Gb
