Reptyr
Reptyr 是一个系统实用程序，专为正在运行的程序重新挂载（reparenting）、管理伪终端以及控制标准输入和输出分配而设计。它作为一个底层 Unix 进程控制器，更新控制终端分配并重定向活动进程的输入和输出。
该工具允许在不中断执行的情况下将正在运行的程序从一个终端会话移动到另一个终端会话。它还提供了用于生成伪终端对和重定向文件描述符以捕获或代理终端会话的实用程序。
该项目涵盖了更广泛的进程管理功能，包括终端断开后的远程会话恢复，以及捕获伪终端主端以附加特定终端上所有进程的能力。
Features
- Interactive Process Redirection - Redirects file descriptors and controlling terminal assignments of active processes to different terminal windows.
- Process Reparenting - Attaches running programs to new terminals by redirecting file descriptors to maintain continuous execution.
- Controlling Terminal Assignments - Implements system call-level updates to process group leaders to restore interactive input from a new terminal.
- File Descriptor Redirection - Provides the ability to redirect process input and output by replacing existing file descriptors with new terminal device handles.
- Process Reparenting Utilities - Provides a utility for moving running programs from one terminal session to another without interruption.
- Process Session Migrations - Changes the session identity of target processes to integrate them into new foreground terminal sessions.
- PTY Interfaces - Generates pseudo-terminal pairs and redirects file descriptors to capture or proxy terminal sessions.
- Pseudo-Terminal Interfaces - Creates and manages pseudo-terminal pairs to redirect process I/O for debugging or proxying.
- Unix Process Management - Functions as a low-level Unix tool to update controlling terminal assignments and redirect standard I/O.
- Process Terminal Migrations - Moves running programs between terminal sessions without stopping their execution.
- Ptrace-Based Attachments - Uses ptrace-based system call interception to seize control of running processes and modify their internal state.
- Interactive Session Recovery - Rescues running processes after terminal disconnects or crashes by attaching them to new active sessions.
- Terminal Session Capturing - Captures the master end of a pseudo-terminal to attach all processes residing on a specific terminal.
- PTY Proxies - Generates pseudo-terminal pairs and proxies the master end to the current session for child processes.
- TTY Attribute Synchronizations - Synchronizes terminal attributes and mode configurations from a new shell to a reparented process.
