vi editor replace all

The syntax for replacing one string with another string in the current line is

:s/pattern/replace/

Here “pattern” represents the old string and “replace” represents the new string. For example, to replace each occurrence of the word “lemon” in a line with “orange,” type:

:s/phpcode/phpcodez/

The syntax for replacing every occurrence of a string in the entire text is similar. The only difference is the addition of a “%” in front of the “s”:

:%s/pattern/replace/

Thus repeating the previous example for the entire text instead of just for a single line would be:

:%s/phpcode/phpcodez/
