For nearly all commands in U-Boot the '?' variable is handled the same way with 0 meaning success, 1 meaning any failure. Explain this in the general rules section of the cmdline documentation (with a link to a counter example) and then remove the redundant wording from most commands. We retain a section about the return value in a number of places where we are doing something such as always returning a specific value or we have useful additional information to go along with the normal return codes.

Description
|
|
-----------
|
|
|
|
The cli command permits getting and changing the current parser at runtime.
|
|
|
|
cli get
|
|
~~~~~~~
|
|
|
|
It shows the current value of the parser used by the CLI.
|
|
|
|
cli set
|
|
~~~~~~~
|
|
|
|
It permits setting the value of the parser used by the CLI.
|
|
|
|
Possible values are old and modern.
|
|
Note that, to use a specific parser its code should have been compiled, that
|
|
is to say you need to enable the corresponding CONFIG_HUSH*.
|
|
Otherwise, an error message is printed.
|
|
|
|
Examples
|
|

|
|

|
|
=> cli set old
|
|
=> cli get
|
|
old
|
|
|
|
Trying to set the current parser to an unknown value::
|
|
|
|
=> cli set foo
|
|
Bad value for parser name: foo
|
|

|
|
|
Usage:
|
|
cli get - print current cli
|
|
set - set the current cli, possible values are: old, modern
|
|
