While working on a new section of the Question-Defense.com web site that will include articles related to Kali Linux I was creating a menu system that would be similar to the Kali Linux menu system. Once the menu was completed with the necessary content and was visually what I was looking for I needed to go back and make some enhancements for SEO (Search Engine Optimization). The goal was to add a HTML title tag where a HTML alt tag already existed and I knew this shouldn’t be to hard to accomplish using regular expressions via TextMate’s find and replace function. Below I describe the issue in more detail along with the regular expression syntax that can be used to accomplish this in the TextMate find and replace window. Please make sure to backup all files you are going to modify before beginning so you can always rollback if need be.
To convert multiple <img> tags in a single HTML file such as
<img src =”hello.jpg” alt = “hello” />
to Ruby on Rails ERB helpers in your .html.erb file like this:
<%= image_tag(“hello.jpg”) %>
The power of the Unix command vi never ceases to amaze me. I have known how to search and replace easily using vi for a long time however I didn’t know how to find and replace plus insert a line break during the replace. After toying around with vi for awhile I was able to figure it out. The example below shows how to find and replace certain text while inserting a line break.
