<div dir="auto">Interesting. For me:</div>
<div dir="auto">bem echo \$HOME </div>

<div>That is because, in the latter case, $HOME is expanded in your current shell, before the command line is executed. When the $ is escaped, as in the first example, then the "$HOME" is expanded when the echo command is actually executed, in a sudo subshell.</div>
<div><br>
</div>
<div>I would expect the second case to produce the same result as just doing "echo $HOME".</div>

<div class="nine-pg" dir="auto">Exactly. I'm puzzled as to how others don't get the expansion in the originating shell in the latter case but as others have said wiki works for them. </div>
