I just discovered /bin/sh is really ash, per /usr/src/bin/sh/TOUR (it supports $(( 1 + 2 )) whereas Bourne sh does not), so I was wondering should sh be a symlink to ash? I don't even see ash in my PATH. // George -- George Georgalis, systems architect, administrator Linux BSD IXOYE http://galis.org/george/ cell:646-331-2027 mailto:george at xxxxxxxxx
