• Man pages:
  • FreeBSD:
    • anacron(8)
    • at(1)
    • cron(8)
    • crontab(1)
    • crontab(5)
    • ntp.conf(5)
    • ntpd(8)
    • periodic(8)
    • periodic.conf(5)
  • Debian:
    • anacron(8)
    • at(1)
    • at.allow(5)
    • cron(8)
    • crontab(1)
    • crontab(5)
    • ntp.conf(5)
    • ntpd(8)
  • CentOS:
    • Unfortunately, the CentOS project has decided to not publish it's manual pages online.
      Your best choice for finding online information about CentOS commands would be the links for Debian above,
      or a project like The Linux man-pages project or Linux man pages @ die.net.
      Keep in mind that paths to files and directories in those documentations
      may differ from those on CentOS.
      Obviously, the CentOS man pages are available at the CentOS command line.
