我的 dotfiles bash 脚本以某种方式删除了它自己的目录？

Question

这是您问题中注释的输出：

drakeprovost@shatterdome:~/RoverCoreOS$ git clone https://github.com/DrakeProvost/dotfiles.git
Cloning into 'dotfiles'...
remote: Enumerating objects: 42, done.
remote: Counting objects: 100% (42/42), done.
remote: Compressing objects: 100% (30/30), done.
remote: Total 42 (delta 21), reused 29 (delta 11), pack-reused 0
Unpacking objects: 100% (42/42), done.

~/RoverCoreOS注意：当您运行上述命令时，您位于该目录中git clone，因此上述命令创建了目录~/RoverCoreOS/dotfiles，而不是~/dotfiles.

drakeprovost@shatterdome:~/RoverCoreOS$ cd dotfiles/
drakeprovost@shatterdome:~/RoverCoreOS/dotfiles$ ls
bash_aliases  bashrc  makesymlinks.sh  README.md  vimrc
drakeprovost@shatterdome:~/RoverCoreOS/dotfiles$ ./makesymlinks.sh 
Creating /home/drakeprovost/dotfiles_old for backup of any existing dotfiles in ~
Moving any existing dotfiles from ~ to /home/drakeprovost/dotfiles_old
Creating symlink to /home/drakeprovost/dotfiles/bash_aliases in ~
Creating symlink to /home/drakeprovost/dotfiles/bashrc in ~
Creating symlink to /home/drakeprovost/dotfiles/vimrc in ~

To complete the setup, please run the following command:

    source ~/.bashrc

drakeprovost@shatterdome:~/RoverCoreOS/dotfiles$ ls
bash_aliases  bashrc  makesymlinks.sh  README.md  vimrc

以上所有事情都发生在~/RoverCoreOS/dotfiles.

drakeprovost@shatterdome:~/RoverCoreOS/dotfiles$ cd

您现在位于目录中~

drakeprovost@shatterdome:~$ ls -al #.bashrc, .vimrc, and .bash_aliases were all red symlinks here, meaning they pointed to non-existent files. Also note that the dotfiles directory has disappeared

~/dotfiles没有消失，它从未存在过。~/RoverCoreOS/dotfiles存在并且可能仍然存在。

...
drakeprovost@shatterdome:~$ git clone https://github.com/DrakeProvost/dotfiles.git
Cloning into 'dotfiles'...
remote: Enumerating objects: 42, done.
remote: Counting objects: 100% (42/42), done.
remote: Compressing objects: 100% (30/30), done.

Unpacking objects: 100% (42/42), done.

现在您已经创建了目录~/dotfiles，从这里开始一切都按您的预期进行。

我建议您修改脚本以添加一些防御性检查。他们无法阻止您执行上述操作，但他们至少可以提醒您一些问题，并且他们会捕获上述问题（假设您的主目录中没有包含dotfiles预期文件的旧目录），例如：

[[ -d "$dir" ]] || { ret="$?"; echo "dir \"$dir\" does not exist"; exit "$ret"; }

for file in $files; do
    [[ -s "$dir/$file" ]] || { ret="$?"; echo "file \"$dir/$file\" does not exist or is empty"; exit "$ret"; }
done

# create dotfiles_old in homedir
echo "Creating $olddir for backup of any existing dotfiles in ~"
mkdir -p "$olddir" || { ret="$?"; echo "Failed to create olddir \"$olddir\""; exit "$ret"; }

您可以根据需要添加其他类似的防御性检查。
