zsh - 有没有办法在 zsh 中抑制交互模式？

Question

在 zsh 中，有没有办法在以交互方式获取的脚本中关闭交互模式(特别是别名)？

例如，如果我在 foo.zsh 中定义:

#!/bin/zsh

a ha

然后做

alias a=echo
./foo.zsh

我收到一个错误，因为没有应用别名；但如果我这样做

. ./foo.zsh

我得到 ha .

有没有办法，在 foo.zsh内, 禁用别名 a ，即使它来自 . ?

这在手册中非常清楚地记录:

INTERACTIVE (-i, ksh: -i)
     This is an interactive shell.  This option is set upon
     initialisation if the standard input is a tty and commands are
     being read from standard input.  (See the discussion of
     SHIN_STDIN.)  This heuristic may be overridden by specifying a
     state for this option on the command line.  The value of this
     option can only be changed via flags supplied at invocation of the
     shell.  It cannot be changed once zsh is running.

但你不需要为了防止别名而关闭交互模式
扩张:

$ setopt no_aliases
$ . ./foo.zsh
./foo.zsh:3: command not found: a
$ setopt aliases   
$ . ./foo.zsh
