## 项目历史与用法

timelimit is a small Unix command-line utility that runs another command and terminates it after an absolute time limit, first with a warning signal and then with a kill signal.

### 项目历史

The official homepage presents timelimit as a process-control utility modelled after the staged signalling pattern used by init during shutdown. It is maintained by Peter Pentchev and developed in the official GitLab repository.

The release archive on the official site lists timelimit 1.0 and later releases through 1.9.2, with source archives, signatures, and downstream Debian and FreeBSD packaging references.

### 采用历史

timelimit entered classic Unix packaging channels because it solves a simple shell problem: bound a command's wall-clock runtime and choose the signals used to stop it.

The input package-manager metadata lists Homebrew, Debian, Nix, and Ubuntu, showing cross-platform package adoption beyond its original release archive. The official release page also links historical Debian snapshots and a FreeBSD port for older releases.

### 使用方式

Typical use is in scripts, tests, batch jobs, and administrative commands where a child process must not run forever. Compared with an ad hoc shell wrapper, timelimit exposes explicit warning and kill stages.

Its utility overlaps with timeout-style tools, but the official description emphasizes absolute execution time and configurable signals.

### 为什么软件包爱好者会关心

timelimit is package-nerd material because it is a tiny command that package managers keep alive for scripting compatibility. It is the kind of Unix utility people install when a shell pipeline needs one sharp behavior and no framework.

### 时间线

- 2015: The official GitLab project was created.
- 1.0: The official homepage lists timelimit-1.0 as an older release with source archive, Debian package links, and a FreeBSD port.
- 1.9.2: The official homepage lists timelimit-1.9.2 as the latest release.

### Related projects

- timelimit is related by purpose to POSIX shell process-control patterns and timeout-style command wrappers.
