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

问题

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.

回答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.

回答2:

You can use . for the current line, like:

:.s/old/new/

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

回答3:

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/n - self explanatory
a - replace all occurrences
q - quit
l - replace the current and stop (last)
^E/^Y - ctrl+e and ctrl+y - scroll down and up respectively.

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