const char kDisableShortHelp[] = "disable: Disable a breakpoint.";
const char kDisableHelp[] =
    R"(disable [ <location> ]

  By default, "disable" will disable the current active breakpoint. It is the
  opposite of "enable". It can be combined with an explicit breakpoint prefix
  to indicate a specific breakpoint to disable.

  In this way, it is an alias for:

    bp set enabled = false

  If a location is given, the command will instead disable all breakpoints at
  that location. Note that the comparison is performed based on input rather
  than actual address, so "disable main" will not disable breakpoints on
  "$main".

Location arguments

)" LOCATION_ARG_HELP("disable")
        R"(

  "help break": To create breakpoints.
  "help breakpoint": To manage the current breakpoint context.
  "help enable": To enable breakpoints.

Examples

  breakpoint 2 disable
  bp 2 disable
      Disable a specific breakpoint.

  disable
      Disable the current breakpoint.
