There are two statements in question:
The shell specifies a default value to PATH.
and
The default path is /bin:/usr/bin:.
The second statement is true. The path search will default to /bin:/usr/bin:.
It doesn't mean that PATH is set to /bin:/usr/bin:.
The first statement is not in the man page that I send out with the
ksh93 source so it must have been added by Solaris. It is not accurate.
