lldb (1) - Linux Man PagesDarwin
NAME lldb- The debugger
SYNOPSIS lldb[-hvdexw ] [-a arch ] [-l script-language ] [-s lldb-commands ] [-n process-name ] [-p pid ] [[--] <PROGRAM-ARG1> <PROGRAM-ARG2> ...]
DESCRIPTION lldbis the command line interface for the LLDB debugger library. lldb can debug C, C++, Objective-C, and Objective-C++ programs.
The following options are available:
- -h, -help
- Prints out the usage information for the lldb debugger. The --help text may be more up-to-date and authoritative than the command line options described in this man page.
- -v, -version
- Prints out the version number of the lldb debugger.
- -a, -arch arch
- Specifies which architecture lldb will use when launching the specified program (assuming the provided executable is built for multiple architectures.)
- -f, -file filename
- Specifies the executable file that will be launching / attaching to.
- -n, -attach-name process-name
- Specifies the name of a currently-running process to attach to. (or the name of a process to wait for if -w is used.)
- -w, -wait-for
- When used in concert with -n process-name-E, indicates that lldb should wait for a new process of that name to be started -- and attach to it as early in the process-launch as possible.
- -p, -attach-pid pid
- Specifies a currently running process that lldb should attach to.
- -l, -script-language 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, -debug
- Tells the debugger to print out extra information for debugging itself.
- -s, -source filename
- Tells lldb to read in and execute the file "filename", which should contain lldb commands.
- -e, -editor
- Instructs lldb to open source files using the host's "external editor" mechanism.
- -x, -no-lldbinit
Do not automatically parse any '.lldbinit' files.
(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.)
USING LLDBIn lldb there is a help command which can be used to find descriptions and examples of all lldb commands. To get help on "breakpoint set" you would type "help breakpoint set".
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.
FILESlldb will read settings/aliases/commands from three files at startup, if they exist.
First, it will read a ~/.lldbinit-debugger command file. If you are using the lldb command line interface, this is ~/.lldbinit-lldb. If you are using lldb inside a GUI debugger like Xcode this will be ~/.lldbinit-Xcode. This is a useful place to put settings that you want to apply only when a given lldb command interpreter is used.
Second, ~/.lldbinit is read.
