Tko to zna?

Apple, apple… mnogi se moji postovi spotiču na ovaj proizvod. I jednako pokušavam otići i malo dalje, no jednostavno jabuka me iz dana u dan fascinira, intrigira i tjera na dijeljenje znanja s vama.

Kako sam neki dan kompletno opisao crond na svom tehničkom dijelu blogosfere, krenuh to iskušati i na jabuci. Rekoh sam sebi, ajmo napraviti jednu malu rsync skripticu i pokušati napraviti remote backup. Pošto mi još džep još ne dopušta kupovinu novog operativnog sustava, koji naravno za sobom vuče i platformu, jerbo sve bi lakše bilo ako imam Time machine, no… nećemo deprimirati.

Kako sam u posjedu starog, dobrog powerpc-a, Tiger-a i posljednje zakrpe, odlučih se poigrati malo. Uglavnom, svi već jednostavno znaju, eto barem oni koji su pratili moje male baljezgarije o jabuci, da je apple os ustvari ništa drugo no linux u pozadini. Pa, tako mora postojati sitni crond u koji mogu ubaciti što želim i to je to. Skripta ne bi trebala nešto pretjerano zahtjeva, jer ako prenesemo jednu datoteku, ostalo je samo igrarija. Pa hajdmo…

Upalih terminal, starog prijatelja i lagano ukucah sljedeće linije:

hankey:~ t2b$ cat /etc/crontab
# The periodic and atrun jobs have moved to launchd jobs
# See /System/Library/LaunchDaemons
#
# minute hour mday month wday who command
hankey:~ t2b$

Molim? Gjde? Što je launchd? Ništa hajmo tamo

hankey:~ t2b$ cd /System/Library/LaunchDaemons/
hankey:/System/Library/LaunchDaemons t2b$ ls -al

Malo sam nakon toga zastao i počeo guglati i evo što pronađoh

Since Mac OS X rarely requires you to reboot, you’ll hardly ever notice it, but Tiger takes less time to start up, thanks to launchd. Launchd provides faster startup through a unified framework for starting, stopping and managing daemons, and incorporates inetd, init, mach_init, System Starter and related services. Administrators have a single mechanism for auditing, configuring and setting resources limits on services.

Pa dooobro. Ono što je bitno, vidjeti vrti li se servis.

hankey:/System/Library/LaunchDaemons t2b$ ps aux | grep launchd
t2b 300 0.0 0.0 27812 4 p1 R+ 7:46PM 0:00.00 grep launchd

Ako pogledate malo gore, možete vidjeti da se struktura mape sadrži dokumente sa ekstenzijama plist. Plist znači property list.
