# This script is used by SMIT to change a print queue's characteristics.
# It accepts arguments in a form like the qprt command (eg. -K+) or the
# chvirprt command (eg. -a _K=+).  It  translates the flags passed in
# and generates the appropriate chvirprt command or chquedev command, depending
# on the attribute being changed.
#
# Usage:  piochpq -q QueueName -d QueueDeviceName [ qprtFlags ] [ chvirprtFlags ]
#
# The first instance of '-q' is considered to by the queue name.  The first instance
# of '-d' is considered to be the queue device name.
#
# Two special cases this command handles are for '-a sa=value' and '-a sf=value'.
# The 'sa' and 'sf' attributes result in the /etc/qconfig file being changed
# instead of the virtual printer.
#
# Also, the '-B' flag results in /etc/qconfig being changed.
