.Sh DESCRIPTION      \" Section Header - required - don't modify
 | 
						|
.Nm
 | 
						|
is the command line interface for the LLDB debugger library. 
 | 
						|
.Nm
 | 
						|
can debug C, C++, Objective-C, and Objective-C++ programs.
 | 
						|
.Pp
 | 
						|
The following options are available:
 | 
						|
.Bl -tag -width indent
 | 
						|
.It Fl h, -help 
 | 
						|
Prints out the usage information for the 
 | 
						|
.Nm
 | 
						|
debugger.  The \fB\-\-help\fR text may be more up-to-date and
 | 
						|
authoritative than the command line options described in this man
 | 
						|
page.
 | 
						|
.It Fl v, -version 
 | 
						|
Prints out the version number of the 
 | 
						|
.Nm 
 | 
						|
debugger.
 | 
						|
.It Fl a, -arch Ar arch
 | 
						|
Specifies which architecture 
 | 
						|
.Nm
 | 
						|
will use when launching the specified program (assuming the provided
 | 
						|
executable is built for multiple architectures.)
 | 
						|
.It Fl f, -file Ar filename
 | 
						|
Specifies the executable file that
 | 
						|
.nm
 | 
						|
will be launching / attaching to.
 | 
						|
.It Fl n, -attach-name Ar process-name
 | 
						|
Specifies the name of a currently-running process to attach to.
 | 
						|
(or the name of a process to wait for if \fB\-w\fR is used.)
 | 
						|
.It Fl w, -wait-for
 | 
						|
When used in concert with \&\fB\-n process-name\-E\fR, indicates that
 | 
						|
.Nm
 | 
						|
should wait for a new process of that name to be started -- and attach
 | 
						|
to it as early in the process-launch as possible.
 | 
						|
.It Fl p, -attach-pid Ar pid
 | 
						|
Specifies a currently running process that
 | 
						|
.Nm
 | 
						|
should attach to.
 | 
						|
.It Fl l, -script-language Ar 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.
 | 
						|
.It Fl d, -debug
 | 
						|
Tells the debugger to print out extra information for debugging itself.
 | 
						|
.It Fl s, -source Ar filename
 | 
						|
Tells 
 | 
						|
.Nm
 | 
						|
to read in and execute the file "\fBfilename\fR", which
 | 
						|
should contain 
 | 
						|
.Nm
 | 
						|
commands.
 | 
						|
.It Fl e, -editor
 | 
						|
Instructs
 | 
						|
.Nm
 | 
						|
to open source files using the host's "external editor" mechanism.
 | 
						|
.It Fl x, -no-lldbinit
 | 
						|
Do not automatically parse any '.lldbinit' files.
 | 
						|
.Pp
 | 
						|
(If you don't provide -f then the first argument will be the file to be debugged
 | 
						|
so 'lldb -- <filename> [<ARG1> [<ARG2>]]' also works.
 | 
						|
Remember to end the options with "--" if any of your arguments have a "-" in them.)
 | 
						|
.El
 | 
						|
.Sh USING LLDB
 | 
						|
In
 | 
						|
.Nm
 | 
						|
there is a \fBhelp\fR command which can be used to find descriptions and examples of
 | 
						|
all 
 | 
						|
.Nm
 | 
						|
commands.  To get help on "\fBbreakpoint set\fR" you would type "\fBhelp breakpoint set\fR".
 | 
						|
.Pp
 | 
						|
There is also an \fBapropos\fR 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, "\fBapropos breakpoint\fR"
 | 
						|
will list any command that has the word \fBbreakpoint\fR in its help text.
 | 
						|
.Sh FILES
 | 
						|
.Nm
 | 
						|
will read settings/aliases/commands from three files at startup, if they exist.
 | 
						|
.Pp
 | 
						|
First, it will read a \fB~/.lldbinit-\fIdebugger\fR command file.  If you are using the
 | 
						|
.Nm
 | 
						|
command line interface, this is \fB~/.lldbinit-lldb\fR.  If you are using 
 | 
						|
.Nm
 | 
						|
inside a GUI debugger like
 | 
						|
.Nm Xcode
 | 
						|
this will be \fB~/.lldbinit-Xcode\fR.  This is a useful place to put settings that you
 | 
						|
want to apply only when a given 
 | 
						|
.Nm
 | 
						|
command interpreter is used.
 | 
						|
.Pp
 | 
						|
Second, \fB~/.lldbinit\fR is read.
 | 
						|
.Pp
 | 
						|
Third, an \fR.lldbinit\fR file in the current working directory (where 
 | 
						|
.Nm
 | 
						|
is started) will be read.
 | 
						|
.Sh SEE ALSO
 | 
						|
The LLDB project page http://lldb.llvm.org/ has many different resources for
 | 
						|
.Nm
 | 
						|
users -- the gdb/lldb command equivalence page http://lldb.llvm.org/lldb-gdb.html can
 | 
						|
be especially helpful for users coming from gdb.
