QNX specific commands

List of interesting (subjective) QNX-specific commands
  • on - usually used for 2 reasons: start new process with specified priority and/or start new process on specific node (it makes possible to start process on different processor/system running QNX - working qnet is required - see Asymmetric multiprocessing (AMP))
  • pidin - process list, frequently more useful than ps, top (e.g. options "-f A", "-f n","threads", "memory", "fds")
  • coreinfo - allows for preliminary corefiles analysis directly on target without using gdb (note that in QNX coredumps are produced by dumper)
  • use - info about specific command (e.g. "use devf-generic", "use -i devf-generic" - for build version)
  • sendnto e.g. "sendnto -d /dev/ttyUSB1 qnx-ifs" (together with "cat /dev/ttyUSB1" and "echo 's' >/dev/ttyUSB1")
