Question - What do you know about wildcard interpretation?
Answer -
Wildcard characters are some special kind of characters that represent one or more other characters. Wildcard interpretation comes into the picture when a command-line contains these characters. In this case, when the pattern matches the input command, these characters are replaced by a sorted list of files.
Asterisk(*) and Question mark(?) are usually used as wildcard characters to set up a list of files while processing.
