Answer 1

Perl thinks that the forward slashes in your dates are actually part of the substitution statement s///g, so you can either escape the slashes in your dates or use a different delimiter for your substitution

perl -pi.back -e 's/2013\/07\/31-05:54:14/2014\/07\/31-00:00:00/g;'

or more readable:

perl -pi.back -e 's#2013/07/31-05:54:14#2014/07/31-00:00:00#g;'
