Answer:
sed 's/CSH$/csh/g' mypasswd > ~/newpasswd
Explanation:
The SED is a stream editor, where s’ which substitutes the “csh” instead of word “CSH” in the file called mypasswd and save the output to the newpasswd. In the screenshot at the attached file shows the data of mypasswd and newpasswd files.
