我运行了一个脚本来设置点文件，但无法撤消

Question

我运行此脚本来设置一些点文件管理：

#!/bin/bash
############################
# .make.sh
# This script creates symlinks from the home directory to any desired dotfiles in ~/dotfiles
############################
########## Variables
dir=~/dotfiles                    # dotfiles directory
olddir=~/dotfiles_old             # old dotfiles backup directory
files="bashrc vimrc vim zshrc oh-my-zsh private scrotwm.conf Xresources"    # 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 ~/dotfiles directory specified in $files
for file in $files; do
    echo "Moving any existing dotfiles from ~ to $olddir"
    mv ~/.$file ~/dotfiles_old/
    echo "Creating symlink to $file in home directory."
    ln -s $dir/$file ~/.$file
done
install_zsh () {
# Test to see if zshell is installed.  If it is:
if [ -f /bin/zsh -o -f /usr/bin/zsh ]; then
    # Clone my oh-my-zsh repository from GitHub only if it isn't already present
    if [[ ! -d $dir/oh-my-zsh/ ]]; then
        git clone http://github.com/michaeljsmalley/oh-my-zsh.git
    fi
    # Set the default shell to zsh if it isn't currently set to zsh
    if [[ ! $(echo $SHELL) == $(which zsh) ]]; then
        chsh -s $(which zsh)
    fi
else
    # If zsh isn't installed, get the platform of the current machine
    platform=$(uname);
    # If the platform is Linux, try an apt-get to install zsh and then recurse
    if [[ $platform == 'Linux' ]]; then
        sudo apt-get install zsh
        install_zsh
    # If the platform is OS X, tell the user to install zsh :)
    elif [[ $platform == 'Darwin' ]]; then
        echo "Please install zsh, then re-run this script!"
        exit
    fi
fi
}
install_zsh

但是，它将我在 bash 终端上的 $ 符号更改为 %，并更改了其他一些内容。

我想知道如何撤消此脚本并将我的 bash 恢复为 $ 符号，我看不到如何恢复所有内容。

Answer 1

它安装了zsh作为默认外壳而不是bash。跑

chsh -s $(which bash)

（读作"将外壳更改为此外壳：哪个文件是 bash"）
