**-f** \<filename\>

- **--file** \<filename\>

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

**-c** \<filename\>

**-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 run 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**

  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**

**-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.
