In Vim, how to search and replace in current line only?

Question

I see how to search and replace in specific lines, specifying by line number, and how to search and replace using the current line as reference to a number of lines down.

How do I search and replace in the current line only? I'm looking for a simple solution that does not involve specifying line numbers as the linked solutions do.

Answer 1

Replace all occurrences of str1 with str2 in certain line:

:s/str1/str2/g

remove the g option if you want to replace only the first occurrence.
