Re: [ferret_users] 'head -1' syntax causes Fprint to fail

[Andrew Wittenberg <Andrew.Wittenberg@xxxxxxxx>]

Hi Remik,

The Fprint script is in

   /usr/local/ferret/bin/Fprint

and one can see the offending line in there.  The first line of that 
script indicates that it's a csh script, not tcsh, so perhaps that's the 
difference.

Since the OS upgrade I've noticed that a lot of my csh scripts have 
broken, and to fix them I've had to change them to tcsh.  You could try 
that with Fprint, or you could just change the offending line to the new 
syntax.  (Actually, I'd be more interested to learn exactly what are the 
differences between the old & new csh!)
