Description:
The text in MySQL Command Line when you type \h gives the following information for the command \c

Initially it says "Type '\c' to clear the buffer."

It does not clear the buffer if it refers to the history of commands in the buffer.

In typing \h to display the help screen it says:

"clear     (\c) Clear command."

In using this command what seems to happen is to actually cancel command execution when typing into the command line interface

How to repeat:
connect to a MySQL server with the command line interface, see text generated and also after typing \h

Suggested fix:
I would remove the "Type '\c' to clear the buffer." or address which buffer it refers to (if any).  

I would change the text in help to say 

"cancel     (\c) Cancel command execution."

Please do not change "clear" to "cancel"; that will require all the manuals to have a version-specific note about the old name of the command.

The effect of \c/clear is to "clear the current input statement". Perhaps that is a sufficient clarification for the help text?
[5 Dec 2008 18:33] Dups Wijay 
Yes "clear current input statement" is fine. But also remove the statement "clear the buffer" cos that is definitely misleading :)
