7.3 Redirections with no command
================================
When a simple command consists of one or more redirection operators and
zero or more parameter assignments, but no command name, zsh can behave
in several ways.
If the parameter NULLCMD is not set or the option CSH_NULLCMD is set,
an error is caused. This is the `csh' behavior and CSH_NULLCMD is set
by default when emulating `csh'.
If the option SH_NULLCMD is set, the builtin `:' is inserted as a
command with the given redirections. This is the default when emulating
`sh' or `ksh'.
Otherwise, if the parameter NULLCMD is set, its value will be used as a
command with the given redirections. If both NULLCMD and READNULLCMD
are set, then the value of the latter will be used instead of that of
the former when the redirection is an input. The default for NULLCMD
is `cat' and for READNULLCMD is `more'.
