root@venus # ./zoneshare -? 
Usage:
	Report:
		./zoneshare -l [-z <zonename>]
			-l list all zones
			-z list only that one
	Manipulate:
		./zoneshare [-l] -z <zonename> -v <value> [-p]
			-l list the changed config
			-z zone to change
			-v new cpu-share value
			-p make the config permanent

# zoneshare v0.4
#
# small script to see and change CPU shares for zones in Solaris.
#
# 17.09.2010, written by Martin Presslaber
#
#
# NOTES:
# Tested on Solaris10 u8 and u9. It won't work with Sol10 releases
# which do not have a cpu-shares property in zonecfg.
# If you have questions or comments feel free to contact me via mail.
#
# Tried to improve that script to run on solaris 11. 
# v0.4 - 29.11.12 Tested and small changes for 11.1
