4.10 Bash - /bin/ksh alternative from FSF

Bash is an alternative to ksh and is availible from prep.ai.mit.edu
and places that mirror the GNU software.  /etc/security/login.cfg
needs to be modified if this will be used as a default shell.

A prebuilt installp (smit) installable package is available from
<http://www-frec.bull.com/>.

[Editor's note: bash's command line expansion and new
 meta-expressions make it an absolute "must" for system
 administrators]
