\fBlldb\fP [\fIoptions\fP] \fIexecutable\fP
.fi
.sp
.SH DESCRIPTION
.sp
\fBlldb\fP is a next generation, high\-performance debugger. It is built as
a set of reusable components which highly leverage existing libraries in the
larger LLVM Project, such as the Clang expression parser and LLVM disassembler.
.sp
\fBlldb\fP is the default debugger in Xcode on macOS and supports
debugging C, Objective\-C and C++ on the desktop and iOS devices and simulator.
.sp
All of the code in the LLDB project is available under the Apache 2.0 License
with LLVM exceptions.

.SH EXAMPLES
.sp
The debugger can be started in several modes.
.sp
Passing an executable as a positional argument prepares \fBlldb\fP to
debug the given executable. Arguments passed after – are considered arguments
to the debugged executable.
.INDENT 0.0
.INDENT 3.5
lldb –arch x86_64 /path/to/program – –arch arvm7
.UNINDENT
.UNINDENT
.sp
Passing one of the attach options causes \fBlldb\fP to immediately attach
to the given process.
.INDENT 0.0
.INDENT 3.5
lldb \-p <pid>
lldb \-n <process\-name>
.UNINDENT
.UNINDENT
.sp
Passing –repl starts \fBlldb\fP in REPL mode.
.INDENT 0.0
.INDENT 3.5
lldb \-r
.UNINDENT
.UNINDENT
.sp
Passing –core causes \fBlldb\fP to debug the core file.
.INDENT 0.0
.INDENT 3.5
lldb \-c /path/to/core
.UNINDENT
.UNINDENT
.sp
Command options can be combined with these modes and cause \fBlldb\fP to
run the specified commands before or after events, like loading the file or
crashing, in the order provided on the command line.
.INDENT 0.0
.INDENT 3.5
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
.UNINDENT
.UNINDENT
.sp
Note: In REPL mode no file is loaded, so commands specified to run after
loading the file (via \-o or \-s) will be ignored.
.SH USING LLDB
.sp
In \fBlldb\fP there is a help command which can be used to find
descriptions and examples of all \fBlldb\fP commands. To get help on
“breakpoint set” you would type “help breakpoint set”.
.sp
There is also an apropos command which will search the help text of all
commands for a given term ‐‐ this is useful for locating a command by topic.
For instance, “apropos breakpoint” will list any command that has the word
“breakpoint” in its help text.
.SH CONFIGURATION FILES
.sp
\fBlldb\fP reads things like settings, aliases and commands from the
.lldbinit file. It will first look for ~/.lldbinit and load that first.
Secondly, it will look for an .lldbinit file in the current working directory.
For security reasons, \fBlldb\fP will print a warning and not source this
file by default. This behavior can be changed by changing the
target.load\-cwd\-lldbinit setting.
.sp
To always load the .lldbinit file in the current working directory, add the
following command to ~/.lldbinit:
.INDENT 0.0
.INDENT 3.5
settings set target.load\-cwd\-lldbinit true
.UNINDENT
.UNINDENT
.sp
To never load the .lldbinit file in the current working directory and silence
the warning, add the following command to ~/.lldbinit:
.INDENT 0.0
.INDENT 3.5
settings set target.load\-cwd\-lldbinit false
.UNINDENT
.UNINDENT
