Don't wanna get all Unix-macho here, but the regular command line is also pretty safe when you're just launching applications and doing things equivalent to the location bar. It gets dangerous for only a specific subset of administrative commands such as rm, mv, apt- which provide different functionality anyway.<p>That said. you can get burnt clobbering important files with output redirection. It's a good idea to enable the "noclobbler" setting in Bash like so:<p><pre><code> set -o noclobber
</code></pre>
It's saved me plenty of times from deleting important partially process data.
The new ones aren't dangerous because you can't actually <i>do</i> anything with them. As soon as I can send an email (or affect the outside world in any way) from the location bar, it becomes just as dangerous as the unix command line.
