Below is a table of GDB commands with their 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", + unique short form can be used. For example, instead of "breakpoint set", "br se" is also acceptable.
