脚本的第二行仅在我通过执行触发全局扩展时才有效echo。我不明白为什么。这是命令，它的执行是为了提供一些上下文。

函数定义：

~/ cat ~/.zsh/includes/ascii2gif
ascii2gif () {
        setopt extendedglob
        input=$(echo ${1}(:a))
        _path=${input:h}
        input_f=${input:t}
        output_f=${${input_f}:r}.gif
        cd $_path
        nerdctl run --rm -v $_path:/data asciinema/asciicast2gif -s 2 -t solarized-dark $input_f $output_f
}

激活 ascii2gif 函数的函数调试..

~/ typeset -f -t ascii2gif

调试功能执行：

~/ ascii2gif ./demo.cast
+ascii2gif:1> input=+ascii2gif:1> echo /Users/b/demo.cast
+ascii2gif:1> input=/Users/b/demo.cast
+ascii2gif:2> _path=/Users/b
+ascii2gif:3> input_f=demo.cast
+ascii2gif:4> output_f=demo.gif
+ascii2gif:5> cd /Users/b
+_direnv_hook:1> trap -- '' SIGINT
+_direnv_hook:2> /Users/b/homebrew/bin//direnv export zsh
+_direnv_hook:2> eval ''
+_direnv_hook:3> trap - SIGINT
+ascii2gif:6> nerdctl run --rm -v /Users/b:/data asciinema/asciicast2gif -s 2 -t solarized-dark demo.cast demo.gif
==> Loading demo.cast...
==> Spawning PhantomJS renderer...
==> Generating frame screenshots...
==> Combining 40 screenshots into GIF file...
==> Done.

我尝试了许多变体来尝试强制扩展input=${~1}(:a)等，但无济于事。有什么建议么？显然脚本有效，但似乎次优。
