检查程序pyprocess是否在运行

# check if previous task is on going.

if ! ps -C $myprocess_BASENAME > /dev/null 2>&1
then
  echo "TRANSFERRING"  > $STATFILE

  # do xxxx

else
  date >> $LOGFILE
  echo "Previous myprocess is not finished." >> $LOGFILE
  echo "So skip syncronizing data."    >> $LOGFILE

  echo "Previous job is not finished."
  echo "So skip executing ${MYNAME}."

  echo "DONE" > $STATFILE
  exit 1
