title: Sed - Replace immediate next string/word coming after a particular pattern
body: <p>I'm a newbie to shell scripting and any help is much appreciated.</p>
  
  <p>I have a pattern like this <code>rmd_ver=1.0.10</code></p>
  
  <p>I want to search the pattern <code>rmd_ver=</code> and replace the numeric part <code>1.0.10</code> with a new value in all the matches. Hope my question is clear.</p>
