d) 1
e) 10

Answer 1

The if command in shell scripting uses an exit code of 0 to denote a true condition. This exit code indicates successful execution without errors.

Step-by-step explanation:

The if command in programming, specifically in shell scripting, looks for an exit code of 0 to consider a condition to be true. When a program or command runs successfully without any errors, it returns an exit code of 0, which the if command interprets as true. Any non-zero exit code is usually considered as false and indicates an error or abnormal completion of the command or program.
