Because zsh contains many features, the zsh manual has been split into
a number of sections:
\fIzsh\fP Zsh overview (this section)
\fIzshbuiltins\fP Zsh built-in functions
\fIzshcompctl\fP Zsh completion control
\fIzshexpn\fP Zsh command and parameter expansion
\fIzshparam\fP Zsh parameters
\fIzshzle\fP Zsh command line editing
\fIzshoptions\fP Zsh options
\fIzshmisc\fP Currently everything else

.SH "DESCRIPTION"
Zsh is a UNIX command interpreter (shell) usable as an interactive
login shell and as a shell script command processor. Of the standard shells,
zsh most closely resembles \fIksh\fR 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.
.SH "INVOCATION OPTIONS"
If the \-\fBs\fP 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 positional
parameters. The following flags are interpreted by the shell
when invoked:
.TP
.PD 0
\-\fBc\fP \fIstring\fP
Read commands from \fIstring\fP.
.TP
\-\fBi\fP
Force shell to be interactive.
.TP
\-\fBs\fP
Read command from the standard input.

.SH STARTUP/SHUTDOWN FILES
Commands are first read from \fB%zshenv%\fP.
If the \fBRCS\fP option is unset
within \fB%zshenv%\fP, all other
initialization files are skipped.
Otherwise, commands are read
from \fB$ZDOTDIR/.zshenv\fP.
(If \fBZDOTDIR\fP is unset, \fBHOME\fP is used instead).
If the first character of argument zero passed to the shell
is \-, or if the \-\fBl\fP flag is present, then the shell is
assumed to be a login shell, and commands
are read from \fB%zprofile%\fP and then \fB$ZDOTDIR/.zprofile\fP.
Then, if the shell is interactive,
commands are read from \fB%zshrc%\fP and then \fB$ZDOTDIR/.zshrc\fP.
Finally, if the shell is a login shell, \fB%zlogin%\fP and
\fB$ZDOTDIR/.zlogin\fP are read.
