Expert Solution

Answer:

grep '[A-Za-z]*' sun.txt

Justification:

grep is the command used to match a regular expression.

[A-Za-z] matches the uppercase or lowercase alphabet from the ASCII characters.

* matches zero or more occurrences of the preceding pattern (i,e. [A-Za-z]* matches zero or more occurrences of words that start with lowercase or the uppercase ASCII characters.)

sun.txt is a file that the grep command looks in to match the given pattern.

sun.txt

Output:

The words marked in red color are the words matched by the regular expression given by us.
