[vox-tech] bash question

[Mark K. Kim]

Shouldn't:

      J=`basename $I .in`
      "$1 > $J.out";
      "$1";

be:

      J=`basename $I .in`
      $1 > $J.out;
      $1;

?  It appears to be treating the whole "$1 > $J.out" as a program name
(including the redirection and the output -- remember *NIX lets you have
any character in program names except for the forward slash) instead of
treating only $1 as a program name.

If you want to allow program names with spaces, I think you want:

      J=`basename $I .in`
      "$1" > $J.out;
      "$1";

Hope that works... I mean, helps!
