步骤1,2 可以通过运行脚本reset_bcompare.sh 实现。

#!/bin/bash

# Beyond Compare 重置脚本
# 用途：重置BCompare的配置和授权信息
# 警告：仅供学习参考，商业使用请购买正版

echo "开始执行Beyond Compare重置操作..."

# 检查是否以root权限运行（因为需要sudo）
if [ "$EUID" -ne 0 ]; then 
    echo "请使用sudo运行此脚本"
    exit 1
fi

# 步骤1: 删除用户配置目录中的bcompare文件夹
echo "步骤1: 删除用户配置目录中的bcompare..."
if [ -d "/home/$SUDO_USER/.config/bcompare" ]; then
    rm -rf "/home/$SUDO_USER/.config/bcompare"
    echo "✓ 已删除 /home/$SUDO_USER/.config/bcompare"
else
    echo "⚠ 目录不存在: /home/$SUDO_USER/.config/bcompare"
fi

# 步骤2: 修改/usr/lib/beyondcompare/目录下的BCompare文件
echo "步骤2: 修改BCompare文件..."
if [ -f "/usr/lib/beyondcompare/BCompare" ]; then
    # 备份原始文件
    cp "/usr/lib/beyondcompare/BCompare" "/usr/lib/beyondcompare/BCompare.bak"
    echo "✓ 已创建备份: /usr/lib/beyondcompare/BCompare.bak"
    
    # 执行sed替换操作
    sed -i "s/keexjEP3t4Mue23hrnuPtY4TdcsqNiJL-5174TsUdLmJSIXKfG2NGPwBL6vnRPddT7tH29qpkneX63DO9ECSPE9rzY1zhThHERg8lHM9IBFT+rVuiY823aQJuqzxCKIE1bcDqM4wgW01FH6oCBP1G4ub01xmb4BGSUG6ZrjxWHJyNLyIlGvOhoY2HAYzEtzYGwxFZn2JZ66o4RONkXjX0DF9EzsdUef3UAS+JQ+fCYReLawdjEe6tXCv88GKaaPKWxCeaUL9PejICQgRQOLGOZtZQkLgAelrOtehxz5ANOOqCaJgy2mJLQVLM5SJ9Dli909c5ybvEhVmIC0dc9dWH+/N9KmiLVlKMU7RJqnE+WXEEPI1SgglmfmLc1yVH7dqBb9ehOoKG9UE+HAE1YvH1XX2XVGeEqYUY-Tsk7YBTz0WpSpoYyPgx6Iki5KLtQ5G-aKP9eysnkuOAkrvHU8bLbGtZteGwJarev03PhfCioJL4OSqsmQGEvDbHFEbNl1qJtdwEriR+VNZts9vNNLk7UGfeNwIiqpxjk4Mn09nmSd8FhM4ifvcaIbNCRoMPGl6KU12iseSe+w+1kFsLhX+OhQM8WXcWV10cGqBzQE9OqOLUcg9n0krrR3KrohstS9smTwEx9olyLYppvC0p5i7dAx2deWvM1ZxKNs0BvcXGukR+/g" /usr/lib/beyondcompare/BCompare
    
    if [ $? -eq 0 ]; then
        echo "✓ 成功修改BCompare文件"
    else
        echo "✗ 修改BCompare文件失败"
        exit 1
    fi
else
    echo "✗ 文件不存在: /usr/lib/beyondcompare/BCompare"
    exit 1
fi

echo "操作完成！"
echo "注意：如果BCompare正在运行，请重启应用使更改生效"

先 chmod +x /home/lilei/reset_bcompare.sh 设置读写权限，然后执行
sudo bash /home/lilei/reset_bcompare.sh
