Does anyone have any opinions on these new options for svcprop?
-1 Can only be used with arguments which specify
a single property. If the property has a single
value, then it is printed, without quotation. If
the property has no values or multiple values,
then svcprop will print nothing and exit with
status 3.
-T type Can only be used with the -1 option. If the
specified property has a type other than _type_
or a subtype of _type_, svcprop will print
nothing and exit with status 4.
This is meant to make it easier for scripts to use svcprop:
val=`svcprop -1 -T astring -p pg/prop service`
case $? in
0) ;;
2) echo "Programmer error." >&2
exit 1
;;
3) echo "pg/prop has no values or multiple values; \c" >&2
echo "using default." >&2
val=default
;;
4) echo "pg/prop has wrong type; using default." >&2
val=default
;;
*) echo "Could not get value of pg/prop; using default." >&2
val=default
;;
esac
Hmm, I wonder if we should also allow svcprop with no operands, which
would automatically use scf_myname() to determine the current service.
