Shell Programming and Scripting

hello dear
i want run this code in cron jobs every 30 minute.please help me how am i send inpot in cron jobs?

The cron facility runs shell scripts. This is not a shell script.

Cron jobs are not interactive. You can redirect input to your cron script in the crontab entry that schedules your cron jobs, or your cron script can read data from a file that will contain the data you want the script to process at the time it is run.

dear what is cron script?

A cron script is the set of shell commands you ask cron to run when you use crontab to schedule a cron job to be run.

at this time i'm need function for send input just only run this functions.later i'm need cron script.

Maybe you should start off by describing clearly what process you need to occur in a logical flow and then show us the code you have written. When you are looking to get input to code being run by cron, it will most likely need to be in a file that can be read in. There is no screen/terminal/console associated with the processes scheduled by cron

If you write your logical steps one on each line then highlight the block and press the LIST button (same as in most word processors) then you can build a list to make it easier to read. You can highlight sections and press the LIST button again to indicate loops if you need to like this:- .... creates this:-
