I am having trouble finding an answer to this question thorough google:
How exatly does CRON in ubuntu execute jobs?
Does it spawn each new job in its own process?
Say i have two cron jobs:
@reboot /some/really/slow/job * * * * * /some/quick/job
Will these jobs run side by side, or will the first one block the second until its done?
Secondly, does Cron affect redirects? Say i have a script which contains something like
rsync --verbose /from /to &>>rsynclog.log
Will the log file be written when called from CRON? Or does it end up somewhere else?
