Gentoo (2002—present) is a source-based [Li|U]nix distribution emphasizing installation of kernels, kernel-optimized services and toolchains, and non-kernel applications and packages via compilation of system-targeted, locally compiled (and, thus, optimized in time and space) code — rather than conventionalized (albiet quicker) re-use of generic, pre-compiled binary packages for installation.
Although a fine and, admittedly, geeky point, the greater point is:
Gentoo manages services, daemons, and other system-wide, widely backgrounded processes via “initscript” shell scripts populating /etc/init.d. Raiazome, in the mediating interests of fun, feebly demagoguery, and pustulant, pulsating hackery, caches a few (non-standard) “initscript” shell scripts — for your Gentoo-standard delight.
rtorrent-screen is an “initscript” shell script for starting, stopping, and otherwise manipulating rtorrent — an ncurses-based, “plain clothes,” plaintext BitTorrent client. See:
cp-pcre is a dependency-less, distro-agnostic Perl script for recursively {a} copying or moving files and/or {b} munging (text) file contents — with promptless, batch efficacy — via Perl Compatible Regular Expression (PCRE)-style search-and-replacement on those things. (This script is not Gentoo-specific; but appears here for continuity with similar simple command-line scripts.) See:
run-crons is a Gentoo-specific (though, probably, distro-agnostic) shell script for auto-scheduling user cronjobs via user-local ~/etc/cron.hourly/, ~/etc/cron.daily/, ~/etc/cron.weekly/, and ~/etc/cron.monthly/ directories. See:
