The problem is that the functionality of echo is a mess among different shells and versions, and there doesn't seem to be any defined standard on its behavior.

The above example is most likely caused because you are using ksh88 in Solaris, and ksh93 in Linux.

So, in this case you shouldn't really be using echo but printf to avoid dealing with these problems.

From ksh93 man page:
Quote:
echo [ arg ... ]
When the first arg does not begin with a -, and none of the arguments contain a \, then echo prints each of its arguments separated by a
space and terminated by a new-line. Otherwise, the behavior of echo is system dependent and print or printf described below should be
used.
