The exit command terminates a script, just as in a C program. It can also return a value, which is available to the script's parent process. Every command returns an exit status (sometimes referred to as a return status or exit code). A successful command returns a 0, while an unsuccessful one returns a non-zero value that usually can be interpreted as an error code.
How to Cook Pork Ribs Using the Low and Slow Method. Start the charcoal 30 minutes prior to cooking. Prepare the grill for indirect grilling. Youâre aiming for a temperature of 225 to 250-degrees F. Place ribs bone side down on the grill grate or use a rib rack if youâre cooking several racks of ribs. If using a rib rack, place the meat side of the ribs facing the fire. Add the smoking chips and cover the grill. On average, baby back ribs will take about 4 hours while spare ribs need about 5. At the outset, your main goal is to watch and adjust the temperature. The heat will have a tendency to climb up to the 300-degree F range rather quickly.
The trick to great ribs is to cook them very slowly with the BBQ sauce on them. You can do this in an oven, just set the temperature to 225Â° F (about 107Â° C). I occasionally use an electric smoker, which cooks at about 200 to 225 degrees Fahrenheit. I've also used this method on my gas grill and in my oven. Cook the ribs for 4Â½ to 5 hours. The time it takes you to cook the ribs may vary depending on the true temperature of your grill, oven, or smoker, the temperature of the ribs when you start, and other factors. Baby back ribs take 30 to 45 minutes less than spareribs.
