vi search and replace

How to do search and replace in Vim.

Search for “foo” and replace it with “bar” in the current line. Use :s

:s/foo/bar/g

Search for “foo” and replace it with “bar” in the entire document. Use :%s

:%s/foo/bar/g

You can also pipe instead of forward slash. Useful if your search contains a /.

:%s|foo/|bar|g
