# This scripts shows a clear and colored status of the ASM used and free space
# Please have a look at the usage function or $0 -h for the available options and their description
# More information and screenshots : https://unknowndba.blogspot.ca/2018/03/asmdush-far-better-du-for-asmcmd.html
#
# A note on the --nocp option
# Note that the --nocp asmcmd option (it disables the connection pooling) has been originaly implemented
# as a workaround of a bug that appeared with the April 2016 PSU
# It resolves error messages like this one :
# sh: -c: line 0: unexpected EOF while looking for matching `''
# sh: -c: line 1: syntax error: unexpected end of file
#
#
# The current version of the script is 20190906
#
# 20190906 - Fred Denis - A new -V option to show the version of the script
# 20190219 - Fred Denis - Some had issues with the instance list, I then moved from sed to cut to fix it -- Thanks Jakub !
# 20181218 - Fred Denis - A new -n option to print with no color -- DEFAULT_NOCOLOR can be used to modify the default behavior
#                         Fixed the regexp to list the instances running
# 20180827 - Fred Denis - A better regexp to list the instances running
# 20180503 - Fred Denis - GI 12c introduces a "Logical_Sector" column, took this into account (Thanks Leon !)
# 20180327 - Fred Denis - "Raw Used " label for the subdirectories "Mirror_used_MB" column, adjustments in the help
# 20180318 - Fred Denis - Shows only mirrored sizes by default and the total non mirrored size only shown with the -v option
# 20180211 - Fred Denis -  Many improvements :
#                       - -d options to list the subdirectories of a directory
#                       - -v option to show the Raw Free and Reserverd size
#                       - -m -g and -t to choose the Unit you want the report to be in
#                       - Default values and verbosity can be changed using the DEFAULT_UNIT and the DEFAULT_VERBOSE variables
#                       - A nice usage function
# 20170719 - Fred Denis - Remove the --nocp option as default
