- --source-on-crash
<file>
- When in batch mode, tells the debugger to source this file of lldb

- --source-quietly
- Tells the debugger to execute this one-line lldb command before any file

- --source
<file>

- -S <value>
- Alias for --source-before-file
- -s <value>

- -x
- Alias for --no-lldbinit
- -r=<flags>
- Alias for --repl=<flags>
--repl-language <language>

- --repl
- Runs lldb in REPL mode with a stub process.

- Alias for --repl-language
- -r
- Alias for --repl
- -l <value>

- -P
- Alias for --python-path
--script-language <language>
- Tells the debugger to use the specified scripting language for
user-defined scripts.
- The debugger can be started in several modes.
- Passing an executable as a positional argument prepares lldb to debug the
given executable. To disambiguate between arguments passed to lldb and
arguments passed to the debugged executable, arguments starting with a -
must be passed after --.
- lldb --arch x86_64 /path/to/program program argument
-- --arch armv7
- For convenience, passing the executable after -- is also
supported.
- lldb --arch x86_64 -- /path/to/program program
argument --arch armv7
- Passing one of the attach options causes lldb to immediately attach to the
given process.
- lldb -p <pid> lldb -n <process-name>
- Passing --repl starts lldb in REPL mode.
- lldb -r
- Passing --core causes lldb to debug the core file.
- lldb -c /path/to/core
- Command options can be combined with these modes and cause lldb to run the
specified commands before or after events, like loading the file or
crashing, in the order provided on the command line.
- lldb -O 'settings set stop-disassembly-count 20' -o 'run'
-o 'bt' lldb -S /source/before/file -s
/source/after/file lldb -K /source/before/crash
-k /source/after/crash
- Note: In REPL mode no file is loaded, so commands specified to run after
loading the file (via -o or -s) will be ignored.
