(lldb) breakpoint
     Commands for operating on breakpoints (see 'help b' for shorthand.)

Syntax: breakpoint <subcommand> [<command-options>]

The following subcommands are supported:

      clear   -- Delete or disable breakpoints matching the specified source
                 file and line.
      command -- Commands for adding, removing and listing LLDB commands
                 executed when a breakpoint is hit.
      delete  -- Delete the specified breakpoint(s).  If no breakpoints are
                 specified, delete them all.
      disable -- Disable the specified breakpoint(s) without deleting them.  If
                 none are specified, disable all breakpoints.
      enable  -- Enable the specified disabled breakpoint(s). If no breakpoints
                 are specified, enable all of them.
      list    -- List some or all breakpoints at configurable levels of detail.
      modify  -- Modify the options on a breakpoint or set of breakpoints in
                 the executable.  If no breakpoint is specified, acts on the
                 last created breakpoint.  With the exception of -e, -d and -i,
                 passing an empty argument clears the modification.
      name    -- Commands to manage name tags for breakpoints
      set     -- Sets a breakpoint or set of breakpoints in the executable.

For more help on any particular subcommand, type 'help <command> <subcommand>'.
