Linux 为UNIX编写了一个bash代码，以充当recyclebin。无法将参数传递给测试函数

我为UNIX的reyclebin文件编写了一个代码。当我bash循环使用ebin-i文件名时， 它读取在文件名之前传递的getopts，然后调用test函数 并进入测试函数，但不进入函数内部的for循环。这个计划没有任何进展，我被困在那里了。有人帮忙吗？我做错什么了

#!bin/bash

### 2. creating directory ~/recyclebin in home if not present
if [[ ! -d $HOME/recyclebin ]]
then
        mkdir $HOME/recyclebin
        #touch $HOME/.restore.info
fi

if [ -d $HOME/recyclebin ] && [ ! -e $HOME/.restore.info ]
then
        touch $HOME/.restore.info
fi

几乎可以肯定的是，您应该在“$@”中为arg使用

，而不是在$*

中为arg使用

——如果文件名包含空格，则使用哪一个非常重要。
if[$#-eq 0]
测试将不执行<只有当
$*
中没有名称时，code>$\

才会为零，如果

$*

中没有名称，则代码不会进入循环。定义函数时，通常最好避免使用关键字

function

。另外，请记住

test

是一个内置命令。编写函数

测试

就像踩在可怕的薄冰上。我不确定这是否是您的问题，但最好避免命名函数

test

，以免与内置函数混淆。我不确定这是你麻烦的原因。我确信它有可能在以后混淆代码的读者。我建议使用它来检查代码是否有错误。如何检查未调用函数

test

？如果像在脚本的最后一行中那样在没有参数的情况下调用它，它将不会做任何事情。您可以在

#之后添加一行
set-x
/bin/bash

（或更高版本），使shell在执行命令之前打印所有命令。在开始调用测试函数时，我忘了在代码的最后传递参数

test$*

。此外，我还将函数测试的名称更改为testCondition，因为测试也是UNX预定义的关键字。@ManiPabla请回答您的问题并显示您正在使用的确切代码，而不是描述对代码的更改。显示如何准确调用脚本以及预期和实际输出。
