Detailed explanation-1: -Shell scripts need to be saved with an extension . sh . Explanation: It’s not mandatory to save script files with . sh extension but we do so for our own convention as it makes it easy to match them with wildcards.
Detailed explanation-2: -sh extension for shell scripts–but it’s not a useful convention. It’s better not to use an extension at all. The advantage of being able tell that foo.sh is a shell script because of its name is minimal, and you pay for it with a loss of flexibility.
Detailed explanation-3: -A shell script usually has the file extension . sh (Bourne or Korn shell) or . csh (C shell). When you run a script or batch file, ESSCMD executes the commands in sequence until it reaches the end of the file.
Detailed explanation-4: -Shell scripts are executed in a separate child shell process. Answer : True.
