[lldb-dev] run after process stop using python API

[Enrico Granata]

$ ./lldb /bin/ls
Current executable set to '/bin/ls' (x86_64).
(lldb) sett set auto-confirm true
(lldb) b malloc
Breakpoint 1: 2 locations.
(lldb) r

You want to set the auto-confirm lldb setting to true before you issue the second run

What exactly are you trying to achieve, if you can discuss it?

If a process is already running, the command interpreter may be waiting for confirmation from the user that it's OK to restart the process (unless you turned off the prompt setting beforehand)... You probably want to issue a "continue" command to restart the process.
