How to search and replace in current line only?

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.

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.

You can use . for the current line, like:

:.s/old/new/

This will change old by new in the current line only.

If you want to search and replace all of the matched word in the current line, you could easily use simple substitute (s) with g modifier in command mode.

:s/search/replace/g

If you just want to search and replace the first matched word in the current line, just move away the g modifier from your command.

:s/search/replace/

Ref: :help substitute

Confirm (c) and Replace :

:s/foo/bar/gc

Find the occurrence of 'foo', and before replacing it with 'bar' ask for confirmation.

Vim gives you these options :

replace with bar (y/n/a/q/l/^E/^Y)?

• y - yes
• n - no
• a - replace all occurrences
• q - quit
• l - replace the current and stop (last)
• ^E (CTRL + e) - scroll down
• ^Y (CTRL + y) - scroll up

Now, in your case you can use the combination of y, n and l to achieve your purpose.
