## Historique du projet et usages

since is a small Unix utility for stateful log tailing: it prints only the content appended to files since the last run.

### Historique du projet

The official homepage describes since as a tail-like Unix utility for monitoring growing log files. The official source archive includes a manpage dated July 1998, and the homepage offers an old stable 0.5 source archive plus a 1.1 rewrite with more features.

### Historique d'adoption

The official homepage links to Debian and FreeBSD distribution pages, and the input records packages for Homebrew, Debian, Fedora/DNF, and Ubuntu. That adoption pattern fits a tiny admin utility preserved by Unix package collections.

### Modes d'utilisation

Users run since against log files, commonly under /var/log, to see only new lines after a previous check. The manpage documents follow mode, quiet and relaxed modes, compressed-extension skipping, and an explicit state-file option.

### Pourquoi les passionnés de paquets s'y intéressent

Package nerds care because since is a minimal example of a Unix command that does one operational job, stores simple state, and avoids a larger log-monitoring stack when a shell session is enough.

### Chronologie

- 1998: Official manpage in the source archive is dated July 1998.
- 2000s: Official homepage lists 0.5 as old and stable and 1.1 as a rewrite with more features.
- 2026: Input package-manager facts list Homebrew, Debian, Fedora/DNF, and Ubuntu packages.

### Related projects

- Related tools include tail, logger, stat, shell aliases for log monitoring, and other stateful log-following scripts.
