Define a command named @var{commandname}. If there is already a command
by that name, you are asked to confirm that you want to redefine it.
The argument @var{commandname} may be a bare command name consisting of letters,
numbers, dashes, and underscores. It may also start with any predefined
prefix command. For example, @samp{define target my-target} creates
numbers, dashes, dots, and underscores. It may also start with any
predefined or user-defined prefix command.
For example, @samp{define target my-target} creates
a user-defined @samp{target my-target} command.
The definition of the command is made up of other @value{GDBN} command lines,

@kindex define-prefix
@item define-prefix @var{commandname}
Define or mark the command @var{commandname} as a user-defined prefix
command. Once marked, @var{commandname} can be used as prefix command
by the @code{define} command.
Note that @code{define-prefix} can be used with a not yet defined
@var{commandname}. In such a case, @var{commandname} is defined as
an empty user-defined command.
In case you redefine a command that was marked as a user-defined
prefix command, the subcommands of the redefined command are kept
(and @value{GDBN} indicates so to the user).
Example:
@example
(gdb) define-prefix abc
(gdb) define-prefix abc def
(gdb) define abc def
Type commands for definition of "abc def".
End with a line saying just "end".
>echo command initial def\n
>end
(gdb) define abc def ghi
Type commands for definition of "abc def ghi".
End with a line saying just "end".
>echo command ghi\n
>end
(gdb) define abc def
Keeping subcommands of prefix command "def".
Redefine command "def"? (y or n) y
Type commands for definition of "abc def".
End with a line saying just "end".
>echo command def\n
>end
(gdb) abc def ghi
command ghi
(gdb) abc def
