软件包摘要
Stateful tail: show changes to files since last check
历史
项目历史与用法
since is a small Unix utility for stateful log tailing: it prints only the content appended to files since the last run.
项目历史
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.
采用历史
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.
使用方式
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.
为什么软件包爱好者会关心
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.
