LLDB(1) User Commands LLDB(1) NAME lldb - manual page for lldb 14 DESCRIPTION OVERVIEW: LLDB USAGE: lldb [options] ATTACHING: --attach-name <name> Tells the debugger to attach to a process with the given name. --attach-pid <pid> Tells the debugger to attach to a process with the given pid. -n <value> Alias for --attach-name -p <value> Alias for --attach-pid --wait-for Tells the debugger to wait for a process with the given pid or name to launch before attaching. -w Alias for --wait-for COMMANDS: --batch Tells the debugger to run the commands from -s, -S, -o & -O, and then quit. -b Alias for --batch -K <value> Alias for --source-on-crash -k <value> Alias for --one-line-on-crash --local-lldbinit Allow the debugger to parse the .lldbinit files in the current working directory, unless --no-lldbinit is passed. --no-lldbinit Do not automatically parse any '.lldbinit' files. --one-line-before-file <command> Tells the debugger to execute this one-line lldb command before any file provided on the command line has been loaded. --one-line-on-crash <command> When in batch mode, tells the debugger to run this one-line lldb command if the target crashes. --one-line <command> Tells the debugger to execute this one-line lldb command after any file provided on the command line has been loaded. -O <value> Alias for --one-line-before-file -o <value> Alias for --one-line -Q Alias for --source-quietly --source-before-file <file> Tells the debugger to read in and execute the lldb commands in the given file, before any file has been loaded. --source-on-crash <file> When in batch mode, tells the debugger to source this file of lldb commands if the target crashes. --source-quietly Tells the debugger not to echo commands while sourcing files or one-line commands provided on the command line. --source <file> Tells the debugger to read in and execute the lldb commands in the given file, after any file has been loaded. -S <value> Alias for --source-before-file -s <value> Alias for --source -x Alias for --no-lldbinit OPTIONS: --arch <architecture> Tells the debugger to use the specified architec- ture when starting and running the program. -a <value> Alias for --arch --capture-path <filename> Tells the debugger to use the given filename for the reproducer. --capture Tells the debugger to capture a reproducer. --core <filename> Tells the debugger to use the full path to <filename> as the core file. -c <value> Alias for --core --debug Tells the debugger to print out extra information for debugging itself. -d Alias for --debug --editor Tells the debugger to open source files using the host's "exter- nal editor" mechanism. -e Alias for --editor --file <filename> Tells the debugger to use the file <filename> as the program to be debugged. -f <value> Alias for --file --help Prints out the usage information for the LLDB debugger. -h Alias for --help --no-use-colors Do not use colors. --reproducer-generate-on-exit Generate reproducer on exit. --version Prints out the current version number of the LLDB debugger. -v Alias for --version -X Alias for --no-use-color REPL: -r=<flags> Alias for --repl=<flags> --repl-language <language> Chooses the language for the REPL. --repl=<flags> Runs lldb in REPL mode with a stub process with the given flags. --repl Runs lldb in REPL mode with a stub process. -R <value> Alias for --repl-language -r Alias for --repl SCRIPTING: -l <value> Alias for --script-language --print-script-interpreter-info Prints out a json dictionary with information about the script- ing language interpreter. --python-path Prints out the path to the lldb.py file for this version of lldb. -P Alias for --python-path --script-language <language> Tells the debugger to use the specified scripting language for user-defined scripts. 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 sup- ported. lldb --arch x86_64 -- /path/to/program program argument --arch armv7 Passing one of the attach options causes lldb to immediately at- tach 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 load- ing 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. lldb 14 February 2023 LLDB(1)
