Neither ssh nor sep like running without a terminal session attached. > Now, I see in man crontab, that it wants me to use launchctl and I looked its > man page too, but I am not seeing how could I schedule the execution of this > script with launched. Scheduling in Launchd is quite simple. <key>StartInterval</key> <integer>1500</integer> To run every 1500 seconds. <key>StartCalendarInterval</key> <dict> <key>Hour</key> <integer>14</integer> <key>Minute</key> <integer>0</integer> </dict> to run at 2pm <key>StartCalendarInterval</key> <dict> <key>Minute</key> <integer>10</integer> </dict> Run at 10 after, every hour. You can also set it to run when a file is changed, when a volume is mounted, or when a file is added to a folder. launched should not have any problem executing your ssh commands as cron does, though. Should work just fine. NB: I do not use StartCalendarInterval on any of my jobs, I just set them for the approximate delay I want them to run. At least back in 10.4, StartCalendarInterval was quite buggy. Check man 5 launchd.plist and note that *missing values are considered to be wildcards*, so if you leave off the minute, it will run every minute, if you leave off the hour, every hour, if you leave off the day, ever day, etc. -- I don't want to sell anything, buy anything, or process anything as a career.
