For convenience, AHF Scope's CLI provides an abbreviation grammar. For example: Instead of typing version, you can simply type v:

cha> version
   CHA UI version:     V1.00.000
   Data version:       V0.17
   PL/SQL package:     V0.10.11.2
   Java version:       1.8.0_77 on Linux

cha> v
   CHA UI version:     V1.00.000
   Data version:       V0.17
   PL/SQL package:     V0.10.11.2
   Java version:       1.8.0_77 on Linux

When more than one command starts with the same prefix, they need to be disambiguated. For example, debug versus device would require typing at least 3 letters to correctly identify the desired command. These commands provide summaries not available in graphical form.
