C-Shell Style Features

The C-Shell (csh) was created by Bill Joy at UC Berkeley. It is generally considered to have better features for interactive use than the original Bourne shell. Some of the csh features present in Bash include job control, history expansion, `protected' redirection, and several variables for controlling the interactive behaviour of the shell (e.g. IGNOREEOF).

See section Using History Interactively for details on history expansion.

• Tilde Expansion: Expansion of the ~ character.
• Brace Expansion: Expansion of expressions within braces.
• C Shell Builtins: Builtin commands adopted from the C Shell.
• C Shell Variables: Variables which Bash uses in essentially the same way as the C Shell.
