## プロジェクトの歴史と使われ方

discoteq flock(1) is a portable command-line implementation of the Unix file-locking utility. It exists for systems where the util-linux flock(1) command is absent, inconvenient, or not portable enough.

### プロジェクトの歴史

The project README explicitly frames the package as an answer to the question of why another flock(1) exists when util-linux already includes one. Its distinguishing goals are support across Linux, Illumos, Darwin, and FreeBSD, testing of major behavior and edge cases, an ISC license, and public source and issue tracking.

The GitHub release history dates the public package line at least to v0.1.1 in 2014, with later v0.2.x releases in 2014 and 2015 and a v0.4.0 release in 2020.

### 採用の歴史

The package is especially relevant on macOS and other non-Linux Unix-like systems because the README gives Homebrew and MacPorts installation paths. The supplied package facts also list Alpine, Nix, and other package-manager entries.

Its adoption pattern is practical rather than framework-driven: shell scripts, cron jobs, backups, and deploy tasks use flock to serialize work with a lock file.

### 使われ方

The common usage is to run flock with a lock-file path followed by a command, such as protecting an echo or rsync invocation so only one instance proceeds at a time.

Because it is a small system utility, its value is in predictable process coordination from shell scripts without embedding lock handling into each script.

### パッケージ好きにとっての重要性

For package maintainers, discoteq flock is a good example of packaging a small compatibility utility to make Unix scripts more portable across distributions and operating systems.

It matters in package-manager culture because the command name overlaps with a util-linux tool: correct formula naming, conflict handling, and platform behavior are the interesting parts, not a large dependency graph.

### タイムライン

- 2014: Public GitHub releases include v0.1.1 and v0.2.0.
- 2015: The v0.2.x release series continues.
- 2020: v0.4.0 is released with source tarball installation instructions referenced by the README.
