#!/usr/bin/ksh
#To get ISN report file from RM
#Author: RuanWX
#Usage: `basename $0` -c origin_command_line -v version i report_id
#in which attributes_string is like: userLabel:neType:availableCapNum
#Please note if an attribute includes metacharacters, the metacharacters must be escaped
#Example: $FDN must be \$FDN
#Or the whole attributes_string is quoted by ', such as '$FDN:userlabel'.
