</span>Yes, that's good. u helps you catch typos in variable names (that otherwise just expand to nothing).<br>
<br>
If you think there might be times when e stops your script and it shouldn't, you can always catch<br>
the error return and do the right thing from there. If you don't know what will cause an error or<br>
you don't know what the right thing is then exiting (via the e) is probably your best choice.<br>
<br>
FWIW<br>
