linux_kill_process
Linux 交互式杀进程工具
一键脚本
bash <(curl -sL gitee.com/meimolihan/linux-command_sh/raw/master/linux_kill_process.sh)
传参模式:
bash <(curl -sL gitee.com/meimolihan/linux-command_sh/raw/master/linux_kill_process.sh) nginx
效果预览
补充说明
该脚本用于交互式终止 Linux 进程，支持无参交互选择、PID 直接终止、名称搜索三种模式，每种模式都会进行 y/n 二次确认，防止误杀。
功能特点
- 三种模式：交互选择 / PID 直杀 / 名称搜索，覆盖各种使用场景
- 二次确认：所有终止操作均提示 y/n 确认，防止误杀
- 彩色输出：进程信息彩色显示，高危操作使用红色警示
- 进程详情：终止前显示用户、PID、CPU、内存、命令等详细信息
- 智能降级：
kill失败自动尝试kill -9强制终止 - 安全性校验：终止前检查进程是否存在，避免操作无效 PID
模式说明
模式一：无参交互（默认）
执行 脚本.sh 后显示 CPU 占用前 30 的进程列表，输入编号选择要终止的进程，确认后执行终止。
1 root 12345 10.5 /usr/bin/nginx -g daemon off;
2 mysql 23456 8.2 /usr/sbin/mysqld
3 www-data 34567 5.1 /usr/sbin/apache2 -k start
...
请输入要终止的进程编号 (1-30) (0 退出):
模式二：按 PID 终止
执行 脚本.sh 12345 直接定位 PID 为 12345 的进程，显示详情后确认终止。
>>> 进程信息
————————————————————————————————————————————————
用户: root
PID: 12345
CPU: 10.5%
内存: 2.3%
命令: /usr/bin/nginx -g daemon off;
————————————————————————————————————————————————
确认终止此进程? [y/N]:
模式三：按名称搜索
执行 脚本.sh nginx 搜索所有匹配 "nginx" 的进程，支持多选或全选终止。
注意事项
- 终止进程需要对应权限（普通用户只能终止自己的进程，root 可终止所有）
- 使用
kill发送 SIGTERM(15) 信号，进程可自行清理退出 - 若
kill失败自动尝试kill -9发送 SIGKILL(9) 信号强制终止 - 交互模式默认显示 CPU 占用前 30 个进程，超出部分不显示
- 名称搜索使用
grep -i忽略大小写匹配 - 脚本过滤了
grep和自身进程，避免误杀
