title: How can i compare two string variable with Jekyll
body: <p>in Jekyll i have tow variable <code>{% assign a="/home/deep" %}</code> and <code>{% assign b="/home/deep/deeper" %}</code> now how can i check if b contains a ? My idea was <code>{% if b contains a %}</code> or <code>{% if b contains "{{ a }}" %}</code>
  but both are always false....</p>
  
  <p>Any idea?</p>
