Advanced Tips for Search-and-Replace in Linux

“Search-and-replace is likely to be the operation you’ll most
often use regexps for in an editor. First let’s look at a
straightforward non-regexp search-and-replace. Let’s say that
you’ve just decided to rename a variable from foo to fooOne. In
Vim, hit Esc for command mode, then use this command:

“:%s/foo/fooOne/g

“% means that the operation should be carried out throughout the
whole document. The important part is s/foo/fooOne/, which means
“replace every instance of ‘foo’ with ‘fooOne'”. The final g means
“global”; without this you’ll just replace the first instance on
every line, but with it, you replace every occurrence.”
