(a) 1,$s/manager/ /g

(b) %s/manager/director/g

(c) 1,$s/professor/director

I have been asked this question during an online interview.

I would like to ask this question from Commands for Searching, Replacing and Substituting in Vi Editor in section The Vi Editor of Unix

Answer 1

The correct option is (a) 1,$s/manager/ /g

To explain: When the target pattern is left empty, then all the instances of the source pattern are deleted within the addressed lines in the file.
