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.
Roasting a chicken does not take quite so long as roasting a turkey, however a large chicken could still take over 2 hours to roast. As a general rule, calculate a cooking time of 20 minutes per pound of meat plus an additional 10 - 20 minutes at a temperature of 375ÂºF (190ÂºC). Therefore, a 5 lb chicken will need to be roasting in the oven for at least 1h 50 mins. A 5 lb bird will serve between 4 - 5 people.
