title: sed Removing whitespace around certain character
body: <p>what would be the best way to remove whitespace only around certain character. Let's say a dash - <code>Some- String- 12345- Here</code> would become <code>Some-String-12345-Here</code>. Something like <code>sed 's/\ -/-/g;s/-\ /-/g'</code> but I am sure there must be a better way.</p>
  
  <p>Thanks!</p>
