1.2.6 Fuzzy Match Support
Switch shell support fuzzy match in searching command and keyword. Shell will recognize com-
mands or keywords correctly if the entered string causes no conflict.
For example:
1. For command show interfaces status ethernet1/1, typing sh in status ethernet1/1 will
work.
2. However, for command show running-config, the system will report a > Ambiguous com-
mand! error if only show r is entered, as Shell is unable to tell whether it is show run or
show running-config. Therefore, Shell will only recognize the command if sh ru is entered.
