<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Those two are examples are the same. If the first didn't work, you<br>probably used single quote characters (') instead of backticks (`). The
<br>backtick should be on the same key as the tilde (~).</blockquote>
<div> </div>
<div>personally I prefer the $( ) form, the backticks can produce semantically ambigous form: you cannot nest command substitution this way</div>
