Re: [SLUG] Bash Script: Spaces in file names

[Chris Donovan <alienresidents@xxxxxxxxx>]

Hi Nigel,

You shouldn't be quoting the escaped string.  Due to the fact that
you're quoting the $TGT, you don't need the second TGT declaration
using the builtin bash regex.  So, either don't quote, or don't escape
the spaces...
