Self-Deleting Script for both Linux Bash and Windows Batch
提问by George Hernando
I have an uninstall script that cleans up an add-on tool used with an application. Versions of the script run on both Windows and Linux.
我有一个卸载脚本，用于清理与应用程序一起使用的附加工具。该脚本的版本可在 Windows 和 Linux 上运行。
I'd like to be able to delete the uninstall script file and also the directory in which the script runs too (in both the case of a Windows batch file and also for the case of a Linux bash file). Right now everything but the script and the directory in which it runs remains after it runs.
我希望能够删除卸载脚本文件以及运行脚本的目录（对于 Windows 批处理文件和 Linux bash 文件）。现在，除了脚本和它运行的目录之外的所有内容在它运行后都保持不变。
How can I delete the script and the script's directory?
如何删除脚本和脚本目录？
Thanks
谢谢

In Bash, you can do
在 Bash 中，你可以这样做
#!/bin/bash
# do your uninstallation here
# ...
# and now remove the script
rm #!/bin/bash

echo "shredding ${currentscript}"
shred -u ${currentscript};
#if current directory is empty, remove it
if [ "$(ls -A ${currentdir})" ]; then

#whenver the script exits call the function "finish"
