我已经修改了shell脚本,将我的dotfile从git存储库符号链接到我的主目录中。除一个问题外,它运作良好……似乎是在目录本身内部创建目录的符号链接。
在下面的脚本中,files变量中的.vscode
条目是目录。最初运行脚本时(未创建符号链接时),一切正常。当我第二次运行脚本时,它仍然可以正常工作。但是,在第三次运行时,在〜/ projects / dotfiles / .vscode文件夹中创建了一个.vscode符号链接。
#!/bin/bash
############################
# makesymlinks.sh
# This script creates symlinks from the home directory to any desired dotfiles in ~/projects/dotfiles
############################
########## Variables
dir=~/projects/dotfiles # dotfiles directory
olddir=~/dotfiles_old # old dotfiles backup directory
files=(.vscode .bash_profile .zshrc .gitconfig) # list of files/folders to symlink in homedir
##########
# create dotfiles_old in homedir
echo -n "Creating $olddir for backup of any existing dotfiles in ~ ..."
mkdir -p $olddir
echo "done"
# change to the dotfiles directory
echo -n "Changing to the $dir directory ..."
cd $dir
echo "done"
# move any existing dotfiles in homedir to dotfiles_old directory, then create symlinks from the homedir to any files in the ~/projects/dotfiles directory specified in $files
for file in $files; do
echo "Moving any existing dotfiles from ~ to $olddir"
mv ~/$file $olddir/
echo "Creating symlink to $file in home directory."
ln -s $dir/$file ~/$file
done
我想防止这种情况的发生,但是我不知道为什么会这样。我该如何预防?
答案 0 :(得分:0)
在ln(1)的手册页中:
-n If the target_file or target_dir is a symbolic link, do not follow
it. This is most useful with the -f option, to replace a symlink
which may point to a directory.
尝试更新您的ln -s
命令以改为使用ln -sfn
。
