为什么我的自定义自动删除 bash 脚本不能正常工作？

Question

我制作了一个 bash 脚本如下：

#!/bin/bash
echo "this is stand-in for 'sudo apt autoremove --purge'"
echo "Uninstalling ..."
apt autoremove --purge
echo "enjoy your free memory..."

但是在变成可执行文件chmod并运行它之后sudo ./script <package_name>，输出是这样的：-

this is stand-in for 'sudo apt autoremove-purge'
Uninstalling ...
Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
enjoy your free memory...

但是如果我使用通常的命令运行相同的代码：- sudo apt autoremove --purge <package_name>，那么它的工作原理如下：-

Building dependency tree       
Reading state information... Done
The following packages will be REMOVED:

我的脚本中缺少什么？

Answer 1

您当前忽略了传递给脚本的参数。

它必须看起来像

#!/bin/bash
apt autoremove --purge "$@"

在"$@"所有的参数求值传递给击你的脚本，所以如果你称呼它

sudo uninstall-this-shit sudoku cowsay sl

它将扩展到sudoku cowsay sl.
