The last command executed in the function or script determines the exit status. Within a script, an. command may be used to deliver an nnn exit status to the shell (nnn must be an integer in the 0 - 255 range). When a script ends with an exit that has no parameter, the exit status of the script is the exit status of the last command executed in the script (previous to the exit).
Quick Answer. A beef roast is cooked in a 375 degrees Fahrenheit oven for 20 minutes per pound. The exact cooking time depends on the size of the roast. The roast is done when it reaches between 135 and 150 degrees Fahrenheit on a meat thermometer.
Place rack back in roasting pan and bake in oven for 10 minutes, reduce temperature to 250Â° and bake for 60-90 minutes (time will vary depending on whether you have a short fat roast or a thin long roast). My roast took 90 minutes to reach 145Â° internal temperature.
