为什么我的自定义自动删除 bash 脚本不能正常工作？

我编写了一个如下的 bash 脚本：

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

但在转换成可执行文件chmod并运行它之后sudo ./script <package_name>，输出如下：-

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>，那么它的工作方式如下：-

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

我的脚本中缺少什么？

答案1

您目前正在忽略传递给脚本的参数。

它必须看起来像

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

计算"$@"Bash 中传递给脚本的所有参数，因此如果你像这样调用它

sudo uninstall-this-shit sudoku cowsay sl

它将扩大到sudoku cowsay sl。

答案2

您需要在内部传递参数

apt autoremove --purge $1

感谢@muru 和@Byte Commander 的注释！

为了使用所有参数，$@应该使用$1

apt autoremove --purge $@
