EXAMPLES:
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.
