Basic Search

search for error by typing /error<CR>

error

Lets type a command in. :set hls ic What just happened? Re-search error

error

But you can do more! try searching /err.*or<CR>

errooentuhoneuhnoteuhnotehuor

• Notice that it matched a huge portion on top. That is because regexs will match the most it can.

Search and Replace

replace "foo" with "baz" by typing :s/foo/baz<CR> foo bar baz

Try again but notice that it only replaces one foo at a time.
foo foo foo foo

replace "foo" with "baz" by typing :s/foo/baz/g<CR> foo foo foo foo

replace "foo" with "baz" by typing :s/foo/baz/gc<CR> foo foo foo foo

Ranged search & replace

function foo() {
    const a = "foo";
    const b = [
        "foo",
        "foo",
        "foo",
        "foo",
    ];
    if ("foo") {
        return "foo";
    }
    return "baz";
}

Full File

Lets execute :%s/foo/bar/gc, but first exit without saving :q! and reopen this file

But what about full project find and replace

I am going to leave this out of this course.
