Linux commands entered via the command line are not case sensitive. True or False?
-
True
-
False
Correct Answer
A. FalseExplanation
Linux commands entered via the command line are case sensitive. This means that the commands must be typed in exactly as they are, with the correct capitalization, in order for them to be recognized and executed properly. For example, "ls" and "LS" would be treated as two different commands and may produce different results. Therefore, the statement that Linux commands are not case sensitive is incorrect.Rate this question:
