Just like llldb, the lldb command interpreter does a shortest unique string match on command names, so the following two commands will both execute the same command: Dump all symbols in a.
This will break on any C functions named main.
No equivalent command – use the source-map instead. We will start with some details on lldb command structure and ccommands to help orient you. Then you can apply the name to your breakpoints, and they will all pick up these options. As with gdb, you can start lldb and specify the file you wish to debug on the command line: The lldb command parser also supports “raw” commands, where, after command options are stripped off, the rest of the command string is passed uninterpreted to the command.
Show the stack backtrace for the current thread. Write a new decimal value to the current thread register rax. Show the arguments that will be or were passed to the program when run. Using the methods command, you can search through interesting code that can help you determine how to uniquely identify a particular SBIconImageView.

Show the general-purpose registers for the current thread. Fortunately, if you don’t like one of our aliases, you an easily get rid of it by running for example: By exploring what others have done, I can learn from their implementations and write better code myself.
You can also make a breakpoint name from the options set on a breakpoint: How helpful is this document? When attaching to a process by name, lldb also supports the ” –waitfor ” option which waits for the next process that has that name to show up, and attaches to it.
