LLDB Debugger commands

https://gist.github.com/wanyakun/314690093ea195d749fca6869ebf200e#file-lldb-debugger-commands-txt Debugger commands: apropos -- List debugger commands related to a word or subject. breakpoint -- Commands for operating on breakpoints (see 'help b' for shorthand.) bugreport -- Commands for creating domain-specific bug reports. command -- Commands for managing custom LLDB commands. disassemble -- Disassemble specified instructions in the current target. Defaults to the current function for the current thread and stack frame. expression -- Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. frame -- Commands for selecting and examing the current thread's stack frames. gdb-remote -- Connect to a process via remote GDB server. If no host is specifed, localhost is assumed. gui -- Switch into the curses based GUI mode. help -- Show a list of all debugger commands, or give details about a specific command. kdp-remote -- Connect to a process via remote KDP server. If no UDP port is specified, port 41139 is assumed. language -- Commands specific to a source language. log -- Commands controlling LLDB internal logging. memory -- Commands for operating on memory in the current target process. platform -- Commands to manage and create platforms. plugin -- Commands for managing LLDB plugins. process -- Commands for interacting with processes on the current platform. quit -- Quit the LLDB debugger. register -- Commands to access registers for the current thread and stack frame. script -- Invoke the script interpreter with provided code and display any results. Start the interactive interpreter if no code is supplied. settings -- Commands for managing LLDB settings. source -- Commands for examining source code described by debug information for the current target process. target -- Commands for operating on debugger targets. thread -- Commands for operating on one or more threads in the current process. type -- Commands for operating on the type system. version -- Show the LLDB debugger version. watchpoint -- Commands for operating on watchpoints. Current command abbreviations (type 'help command alias' for more info): add-dsym -- ('target symbols add') Add a debug symbol file to one of the target's current modules by specifying a path to a debug symbols file, or using the options to specify a module to download symbols for. attach -- ('_regexp-attach') Attach to process by ID or name. b -- ('_regexp-break') Set a breakpoint using one of several shorthand formats. bt -- ('_regexp-bt') Show the current thread's call stack. Any numeric argument displays at most that many frames. The argument 'all' displays all threads. c -- ('process continue') Continue execution of all threads in the current process. call -- ('expression --') Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. continue -- ('process continue') Continue execution of all threads in the current process. detach -- ('process detach') Detach from the current target process. di -- ('disassemble') Disassemble specified instructions in the current target. Defaults to the current function for the current thread and stack frame. dis -- ('disassemble') Disassemble specified instructions in the current target. Defaults to the current function for the current thread and stack frame. display -- ('_regexp-display') Evaluate an expression at every stop (see 'help target stop-hook'.) down -- ('_regexp-down') Select a newer stack frame. Defaults to moving one frame, a numeric argument can specify an arbitrary number. env -- ('_regexp-env') Shorthand for viewing and setting environment variables. exit -- ('quit') Quit the LLDB debugger. f -- ('frame select') Select the current stack frame by index from within the current thread (see 'thread backtrace'.) file -- ('target create') Create a target using the argument as the main executable. finish -- ('thread step-out') Finish executing the current stack frame and stop after returning. Defaults to current thread unless specified. image -- ('target modules') Commands for accessing information for one or more target modules. j -- ('_regexp-jump') Set the program counter to a new address. jump -- ('_regexp-jump') Set the program counter to a new address. kill -- ('process kill') Terminate the current target process. l -- ('_regexp-list') List relevant source code using one of several shorthand formats. list -- ('_regexp-list') List relevant source code using one of several shorthand formats. n -- ('thread step-over') Source level single step, stepping over calls. Defaults to current thread unless specified. next -- ('thread step-over') Source level single step, stepping over calls. Defaults to current thread unless specified. nexti -- ('thread step-inst-over') Instruction level single step, stepping over calls. Defaults to current thread unless specified. ni -- ('thread step-inst-over') Instruction level single step, stepping over calls. Defaults to current thread unless specified. p -- ('expression --') Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. parray -- ('expression -Z %1 --') Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. po -- Evaluate an expression on the current thread. Displays any returned value with formatting controlled by the type's author. poarray -- ('expression -O -Z %1 --') Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. print -- ('expression --') Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. q -- ('quit') Quit the LLDB debugger. r -- ('process launch -X true --') Launch the executable in the debugger. rbreak -- ('breakpoint set -r %1') Sets a breakpoint or set of breakpoints in the executable. repl -- ('expression -r -- ') Evaluate an expression on the current thread. Displays any returned value with LLDB's default formatting. run -- ('process launch -X true --') Launch the executable in the debugger. s -- ('thread step-in') Source level single step, stepping into calls. Defaults to current thread unless specified. si -- ('thread step-inst') Instruction level single step, stepping into calls. Defaults to current thread unless specified. sif -- Step through the current block, stopping if you step directly into a function whose name matches the TargetFunctionName. step -- ('thread step-in') Source level single step, stepping into calls. Defaults to current thread unless specified. stepi -- ('thread step-inst') Instruction level single step, stepping into calls. Defaults to current thread unless specified. t -- ('thread select') Change the currently selected thread. tbreak -- ('_regexp-tbreak') Set a one-shot breakpoint using one of several shorthand formats. undisplay -- ('_regexp-undisplay') Stop displaying expression at every stop (specified by stop-hook index.) up -- ('_regexp-up') Select an older stack frame. Defaults to moving one frame, a numeric argument can specify an arbitrary number. x -- ('memory read') Read from the memory of the current target process.
