Zsh is an interactive Unix shell similar to the well-known Korn shell, with adaptations from bash and tcsh. It provides a powerful scripting language with loadable extension modules, a bash compatibility mode, an advanced command line interface, a session-shared history, spelling correction, adaptable line editing, powerful filename matching, programmable command completion with support for most common Unix uilities.
minor documentation: The 'exec' and 'command' precommand modifiers, and options to them, are Now parsed after parameter expansion. Previously, both the modifier and Any options to it were parsed between alias expansion and parameter Expansion (see zshexpn(1)), so they could neither be quoted nor be the Result of parameter expansion. Examples: 's=command; s -V ls' and ' command -V ls' now work as expected.
