This is GNU Bash.  Bash is the GNU Project's Bourne Again SHell, a
complete implementation of the POSIX.2 shell spec, but also with
interactive command line editing, job control on architectures that
support it, csh-like features such as history substitution and brace
expansion, and a slew of other features.  For more information on the
features of Bash that are new to this type of shell, see the file
`doc/features.texi'.  There is also a large man page.  The manual page
is the definitive description of the shell's features.
