Polling continously for presence of a file
Hi,
My os is sun solaris 5.10 and Korn shell scripting.

I have a file name like CCNA_EARLY_SWP.w062309
where 062309 is date in mmddyy .This is the value date of the file.(will
I need to check continously from 5.00 - 7.00 am daily for this file .
If the file has not come at 5 am or 7am ,I need tor aise alert message.
If the file has not come at 7am , i need to exit from script with error return code.
Apart from this, I do not want to poll continously , if the time is not between 5.00 and 7.00 am , but only check for presence of file,if present do next step otherwise exit with error code.

Can anyone give some good example to proceed

before checking for file get the time stamp if it is not in your range --sleep for some time and then wake up
If your bail out time reach and still the file not present --Sent a mail and Exit from the script

You can consider using scheduler -like Autosys which is equiped with file watcher functionality
