Re: [DIYbio] OpenPCR + Terminal: Any leads?

Hm. Typing "strace -e trace=write /opt/OpenPCR/bin/OpenPCR" yields only
the following:
--- SIGCHLD (Child exited) @ 0 (0) ---
--- SIGCHLD (Child exited) @ 0 (0) ---
--- SIGCHLD (Child exited) @ 0 (0) ---
--- SIGCHLD (Child exited) @ 0 (0) ---
--- SIGCHLD (Child exited) @ 0 (0) ---
--- SIGCHLD (Child exited) @ 0 (0) ---

Glancing at the man-files for strace suggests that it actually
calls/executes the program you specify, which probably isn't compatible
with an Air app.

How would one hax strace to monitor an existing process? It opens a
process named "OpenPCR", you can get the process ID with "pidof OpenPCR".
