To ease the adoption of LLDB for users coming from GDB, I've added the
command line option -ex to the lldb binary. It is an alias to the
--one-line option which
Tells the debugger to execute this one-line lldb command after any
file provided on the command line has been loaded.
This is probably as close as we can get to gdb's -ex option which
has this documentation:
-ex commandExecute given GDB command.
