Run cron jobs with overrun protection
历史
lockrun is a small public-domain Unix utility by Steve Friedl for running cron jobs with overrun protection. It wraps a command, takes an advisory file lock, and prevents overlapping invocations from piling up.
The official Unixwiz.net page explains that lockrun was created in response to network-monitoring cron jobs that could run longer than their schedule interval. The tool was designed as a protective wrapper that checks whether another protected instance is already running before launching the requested command.
lockrun is distributed as portable C source code rather than through a hosted source repository. The official page documents building it with `gcc lockrun.c -o lockrun` and installing it into `/usr/local/bin`.
The tool's natural audience is Unix administrators with cron jobs that must not overlap, especially polling and monitoring jobs. It was tested on FreeBSD and Linux, received a report of working on Mac OS X, and later gained portability work such as Solaris `lockf()` support.
Homebrew and Alpine packaging made the small C utility easier to install without manually downloading and compiling the source file.
A typical crontab entry invokes `lockrun --lockfile=/var/run/name.lockrun -- command`. If the lock cannot be acquired, lockrun exits instead of launching a second copy; `--wait`, `--quiet`, `--verbose`, and `--maxtime` adjust behavior.
The official documentation warns that the lockfile should be placed in a directory protected from other users and not in `/tmp`, because a writable directory could enable symlink attacks against the lockfile path.
lockrun is package-manager-relevant because it solves a narrow operations problem with one C file and no daemon. It overlaps with `flock(1)` patterns, but its documented cron-oriented interface made it a remembered admin tool.
Its packaging story is also a reminder that not every useful Unix package has a modern VCS repository; sometimes the authoritative upstream is a source file and a carefully written HTML manual.
