Howdy,

I thought that by default echo always adds its own new line at the  
end before ``exiting.'' E.g.,

echo Hello ; echo " World"

prints

Hello
  World

on separate lines. I think the -n option was meant to suppress this  
newline so a line could be continued; e.g.

echo -n Hello ; echo " World"

prints out

Hello World

all on a single line. I think the -n option is standard in bash but  
not in sh.

There is also an echo command in /bin/ that does accept the -n option  
so you could replace

echo -n ...

by

/bin/echo -n ...

or use Apple's suggestion of

printf "%s" ...

or change from sh to bash.

Good Luck,
