Question

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。

我希望能够删除卸载脚本文件以及脚本运行的目录（在Windows批处理文件的情况下以及Linux bash文件的情况下）。现在，除了脚本和运行它的目录之外的所有东西都会在运行后保留。

如何删除脚本和脚本的目录？

Answer 1

在Bash中，你可以做到

#!/bin/bash
# do your uninstallation here
# ...
# and now remove the script
rm $0
# and the entire directory
rmdir `dirname $0`

# Purpose: securely self-deleting shell script, delete current directory if empty
# http://brakertech.com/self-deleting-bash-script

#set some variables
currentscript=$0
currentdir=$PWD

#export variable for use in subshell
export currentdir

# function that is called when the script exits
function finish {
    #securely shred running script
    echo "shredding ${currentscript}"
    shred -u ${currentscript};

    #if current directory is empty, remove it    
    if [ "$(ls -A ${currentdir})" ]; then
       echo "${currentdir} is not empty!"
    else
        echo "${currentdir} is empty, removing!"
        rmdir ${currentdir};
    fi

}

#whenver the script exits call the function "finish"
trap finish EXIT

#last line of script
echo "exiting script"
