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.
