$ kvget <key>              # get value of key
$ kvdel <key>              # delete by key
$ kvlist                   # list all current key/value pairs
$ kvclear                  # clear database

Examples

$ kvclear

Test result:

RUN ALL TEST CASES:
===================
  1 call kvget for non-exist key should return empty  OK
  2 kvset then kvget a variable                       OK
  3 kvset then kvset again with different value       OK
  4 deleted variable should be empty                  OK
  5 kvdel non exist should be OK                      OK
  6 kvset without param return error                  OK
  7 kvget without param return error                  OK
  8 kvdel without param return error                  OK
  9 kvset 3 keys/value; kvlist => line count = 3      OK
 10 non-exist-var => empty value => line count = 1    OK
 11 kvclear; kvlist => line count = 0                 OK
 12 kvget return empty value => error code != 0       OK
 13 spaces in value                                   OK
