Is there any regex to delete a complete line and replace with another line....

For eg:

macros perl
macros monks
macros one liner
macros

have to be converted as 

macros regex
macros regex
macros regex
macros regex

[download]

Whatever follows macros whether it is empty or followed by a string have to be replaced with regex and All macros will be at the beginning of the line so we can include ^ character in the regex.

Thanks Monks

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
