## プロジェクトの歴史と使われ方

detach is a small Unix-style command for starting another process outside the control of the current terminal. Its official page frames it as a portable utility that forks, detaches from the terminal, and then executes the requested command.

### プロジェクトの歴史

Robbert Haarman's official detach page is dated 2010-12-11 and still presents the project as a minimalist command-line tool. The page offers an initial 0.1.0 source release and a later 0.2.3 release that added pidfiles, explicit stdin/stdout/stderr files, and a foreground mode.

### 採用の歴史

detach occupies the old-school Unix packaging niche: tiny source tarball, Makefile installation, and availability through package managers for users who want a command rather than a shell built-in. Its official documentation emphasizes portability across OpenBSD, NetBSD, GNU/Linux, and Mac OS X rather than a large plugin ecosystem.

### 使われ方

The common use case is launching a command so it survives terminal exit without depending on shell job control. The official examples compare it with setsid, disown, and nohup, and show why a standalone executable can be useful from scripts or other programs.

### パッケージ好きにとっての重要性

For package nerds, detach is interesting because it packages one precise process-control behavior as a tiny, portable C utility. It sits in the same mental drawer as nohup, setsid, daemon helpers, and shell job-control commands, but with a deliberately narrow interface.

### タイムライン

- 2010: Official detach page dated 2010-12-11 documents the tool and source releases.
- 2010: Initial 0.1.0 release provided the minimal command-running behavior.
- 2010: Release 0.2.3 added pidfiles, stream-file options, and foreground execution.

### Related projects

- The official documentation directly compares detach with util-linux setsid, shell disown built-ins, and POSIX-style nohup.
