Crontab entry to schedule a script every 14 days

[senrooy]

I need to schedule a script through crontab file so that it runs every 14 days.
Can anyone tell me what should be the crontab entry for this?

[kmitnick]

what is crontab???

[sahabcse]

# m h dom mon dow command
* * */14 * * your script file

[peteh]

# m h dom mon dow command
* * */14 * * your script file

I'm not sure that works. It would be every 14 days within the month, I think. That's 14th and 28th each time.
Please let me know if I'm wrong.

I have tried with this command. It runs the script on 14th and 28th of every month,not after every 14 days

i see it the same there is sometimes a 1 day delay and some times it i s2 days,

According to the requirement the schedule date should not be date specific i.e. on14th and 28th for example. It should run after every 14 days. I have tried with the above command. But it won't work as per requirement

I am currently learning shell scripting right now using book from Bible, it is awesome by the way, anyway, what I am going to say is that if you can make a script every day and inside make the 14 days check, so you have to save the last date in a file and every day it is checked if the current date minus the date in the file =14 then run the other script ( your desired script) and save the current date in the file and so on.

NOTE:I am new to shell scripting so I don't know how is this can be done...

I wonder if it's even possible. I've done some Google searches and every time I see people telling others it's impossible. I think you should handle it in your own code and let cron call it every week (lets say day 1 of week, that's possible). I don't really know anything else.
