title: Assignment of variables with space after the (=) sign?
body: <p>In Bash, assigning values to variables is done using <code>T=content</code>, with no spaces before or after the equal sign. </p>
  
  <p>Despite that I've seen the following in a shell script <code>PWD= /bin/pwd</code>  containing a space on the right side of the equals sign. </p>
  
  <p>What's the purpose of it have a space?</p>
