NAME zsh - the Z shell SYNOPSIS Because zsh contains many features, the zsh manual has been split into a number of sections: zsh Zsh overview (this section) zshbuiltins Zsh built-in functions zshcompctl Zsh completion control zshexpn Zsh command and parameter expansion zshparam Zsh parameters zshzle Zsh command line editing zshoptions Zsh options zshmisc Currently everything else zshall Meta-man page containing all of the above DESCRIPTION Zsh is a UNIX command interpreter (shell) usable as an interactive login shell and as a shell script command pro- cessor. Of the standard shells, zsh most closely resembles ksh but includes many enhancements. Zsh has comand line editing, builtin spelling correction, programmable command completion, shell functions (with autoloading), a history mechanism, and a host of other features. INVOCATION OPTIONS If the -s flag is not present and an argument is given, the first argument is taken to be the pathname of a script to execute. The remaining arguments are assigned to the posi- tional parameters. The following flags are interpreted by the shell when invoked: -c string Read commands from string. -i Force shell to be interactive. -s Read command from the standard input. STARTUP/SHUTDOWN FILES Commands are first read from /etc/zshenv. If the RCS option is unset within /etc/zshenv, all other initialization files are skipped. Otherwise, commands are read from $ZDOTDIR/.zshenv. (If ZDOTDIR is unset, HOME is used instead). If the first character of argument zero passed to the shell is -, or if the -l flag is present, then the shell is assumed to be a login shell, and commands are read from /etc/zprofile and then $ZDOTDIR/.zprofile. Then, if the shell is interactive, commands are read from /etc/zshrc and then $ZDOTDIR/.zshrc. Finally, if the shell is a login shell, /etc/zlogin and $ZDOTDIR/.zlogin are read. FILES $ZDOTDIR/.zshenv $ZDOTDIR/.zprofile $ZDOTDIR/.zshrc $ZDOTDIR/.zlogin $ZDOTDIR/.zlogout ${TMPPREFIX}* (default is /tmp/zsh*) /etc/zshenv /etc/zprofile /etc/zshrc /etc/zlogin /etc/zlogout AUTHOR Zsh was originally written by Paul Falstad <pjf@cts.com>. Zsh is now maintained by the members of the zsh workers mailing list zsh-workers@math.gatech.edu. The development is currently coordinated by Zoltan Hidvegi <hzoli@cs.elte.hu>.
