My bad, I forgot the end of the command:

-p $$

(insert just before the final ampersand)

Command explained:

strace: traces all system calls and signalx of a process;
-f: trace across forks and new processes;
-e execve: only trace the execve system call, i.e. executing a new command;
-s 10000: truncate stings with a very high limit;
-o /tmp/...: dump output in a file with an unique name;
-p $$: trace the calling shell;
&: run in background.
