Below is a table of GDB commands with the LLDB counterparts. The built in GDB-compatibility aliases in LLDB are also listed. The full lldb command names are often long, but any unique short form can be used. Instead of "breakpoint set", "br se" is also acceptable.

EVALUATING EXPRESSIONS
| GDB | LLDB |
| Evaluating a generalized expression in the current frame. | |
| (gdb) print (int) printf ("Print nine: %d.", 4 + 5) or if you don't want to see void returns: (gdb) call (int) printf ("Print nine: %d.", 4 + 5) |
(lldb) expr (int) printf ("Print nine: %d.", 4 + 5) or using the print alias: (lldb) print (int) printf ("Print nine: %d.", 4 + 5) |
| Creating and assigning a value to a convenience variable. | |
| (gdb) set $foo = 5 (gdb) set variable $foo = 5 or using the print command (gdb) print $foo = 5 or using the call command (gdb) call $foo = 5 and if you want to specify the type of the variable:(gdb) set $foo = (unsigned int) 5 |
In lldb you evaluate a variable declaration expression as you would write it in C: (lldb) expr unsigned int $foo = 5 |

(lldb) expr -i 0 -- function_with_a_breakpoint() |
| Calling a function that crashes, and stopping when the function crashes. | |
| (gdb) set unwindonsignal 0 (gdb) p function_which_crashes() |
(lldb) expr -u 0 -- function_which_crashes() |
