-h

-v

--version

    Prints out the current version number of the LLDB debugger.

-a <arch>

--arch <arch>

    Tells the debugger to use the specified architecture when starting and running the program. <architecture> must be one of the architectures for which the program was compiled.

-f <filename>

--file <filename>

    Tells the debugger to use the file <filename> as the program to be debugged.

-c <filename>

--core <filename>

    Tells the debugger to use the fullpath to <path> as the core file.

-p <pid>

--attach-pid <pid>

    Tells the debugger to attach to a process with the given pid.

-n <process-name>

--attach-name <process-name>

    Tells the debugger to attach to a process with the given name.

-w

--wait-for

    Tells the debugger to wait for a process with the given pid or name to launch before attaching.

-s <filename>

--source <filename>

    Tells the debugger to read in and execute the lldb commands in the given file, after any file provided on the command line has been loaded.

-o

--one-line

    Tells the debugger to execute this one-line lldb command after any file provided on the command line has been loaded.

-S <filename>

--source-before-file <filename>

    Tells the debugger to read in and execute the lldb commands in the given file, before any file provided on the command line has been loaded.

-O

--one-line-before-file

    Tells the debugger to execute this one-line lldb command before any file provided on the command line has been loaded.

-k

--one-line-on-crash

    When in batch mode, tells the debugger to execute this one-line lldb command if the target crashes.

-K <filename>

--source-on-crash <filename>

    When in batch mode, tells the debugger to source this file of lldb commands if the target crashes.

-Q

--source-quietly

    Tells the debugger to execute this one-line lldb command before any file provided on the command line has been loaded.

-b

--batch

    Tells the debugger to running the commands from -s, -S, -o & -O, and then quit. However if any run command stopped due to a signal or crash, the debugger will return to the interactive prompt at the place of the crash.

-e

--editor

    Tells the debugger to open source files using the host's "external editor" mechanism.

-x

--no-lldbinit

    Do not automatically parse any '.lldbinit' files.

-X

--no-use-colors

    Do not use colors.

-P

--python-path

    Prints out the path to the lldb.py file for this version of lldb.

-l <script-language>

--script-language <script-language>

    Tells the debugger to use the specified scripting language for user-defined scripts, rather than the default. Valid scripting languages that can be specified include Python, Perl, Ruby and Tcl. Currently only the Python extensions have been implemented.

-d

--debug

    Tells the debugger to print out extra information for debugging itself.

-r

--repl

    Runs lldb in REPL mode with a stub process.

-R

--repl-language

    Chooses the language for the REPL.

    Notes:

Multiple "-s" and "-o" options can be provided.
    They will be processed

    from left to right in order, with the source files and commands interleaved. The same is true of the "-S" and "-O" options. The before file and after file sets can intermixed freely, the command parser will sort them out. The order of the file specifiers ("-c", "-f", etc.) is not significant in this regard.

    If you don't provide -f then the first argument will be the file to be debugged which means that 'lldb -- <filename> [<ARG1> [<ARG2>]]' also works. But remember to end the options with "--" if any of your arguments have a "-" in them.
