# svcadm accept any complete FMRI or abreviated FMRI
|
|
# - a complete FMRI is svc:/foo/bar/bar/baz
|
|
# - abbreviated FMRI are foo/bar/bar/baz, bar/bar/baz, bar/baz or baz
|
|
#
|
|
# The goal of this function is to be able to propose all alternatives,
|
|
# but to not clutter the interface with all completions, we will only
|
|
# cut every completion alternative at the next slash.
|
|
#
|
|
# For exemple, if the user types <nothing><tab>, we will propose for svc://foo/bar/bar/baz
|
|
# the following completion: foo/, bar/ and baz
|
|
# If the user types <b><tab>, we will propose: bar/ and baz
|
|
# If the user types <bar/><tab>, we will propose: bar/bar/ and bar/baz
|
|
#
|
|
# By default, the function proproses only abbreviated completions except if the user already
|
|
# began to type svc:. In that case we will propose only the complete FMRI beginning with the
|
|
# pattern
