These 35 built-ins will not be part of the namespace...there
will not be a /usr/ast/bin directory nor any files.
They will only be available in ksh93 as built-ins, which have
pathname binding to /usr/ast/bin. This means that if these
commands are called without a pathname prefix, the built-ins
will be invoked in ksh93 if it finds /usr/ast/bin on the user's path first,
before finding an executable with that name. These built-ins
are common commands that are not built-ins in the Solaris ksh:
cp, chmod, join, tail, tee, etc. Most of them are not deemed
compatible with the corresponding Solaris commands, so they are
not enabled by default. The user needs to put a new pathname,
/usr/ast/bin, on their path to use them.
Some ksh93 users rely on the features available in the AT&T versions
of these commands or have ksh93 scripts which make heavy use of the
commands and gain better performance when calling them as
built-ins rather than binaries.
