Vim - Performing substitution on certain lines only
问题 I have found the following in my quest to perform a substitution on even numbered lines only: :g/^/if !(line('.')%2)|s/foo/bar/g|endif Works great. But can someone please explain the need for the | characters in the command section of the :g call? 回答1: The | character is the command separator ; with it, you can concatenate multiple Ex commands in a single line, without adding newlines. See :help :bar. So, your conditional is equivalent to the following: if !(line('.')%2) s/foo/bar/g endif
