<html><head></head><body>Of course! And, why not escape everything else, too?<br>
<br>
abc -> ^a^b^c<br>
<br>
echo %PATH% -> ^e^c^h^o^ ^%^P^A^T^H^%<br>
<br>
In all seriousness, to me this is obvious. When you pass a command to the shell, naturally, certain details are shell-specific.<br>
<br>
-10000. Bad idea. Very bad idea. If you want the ^ to be escaped, do it yourself. Or better yet, don't pass shell=True.<br><br><div class="gmail_quote">anatoly techtonik <techtonik@gmail.com> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
