Bourne Shell Style Features
Bash is an acronym for Bourne Again SHell. The Bourne shell is the
traditional Unix shell originally written by Stephen Bourne. All of
the Bourne shell builtin commands are available in Bash, and the rules
for evaluation and quoting are taken from the Posix 1003.2
specification for the `standard' Unix shell.
