Shell Programming and Scripting

All,

I have to write a script to do the following requirement.
There is a file called BUSINESS_DATE.TXT.
This file get updated once the oracle partition created. In Oracle, Partition will be created every day. There is a seperate script scheduled to take care ORACLE partition creation.
The above file will have only one row. i.e
03092012
If Oracle partition creation job failed, the above file won't be updated.
My requirement is,
I have to check whether the BUSINESS_DATE file is updated today or not. If yes, I will have to move the files from common area to input file directory to process those files.
All file name will amend with current date.
i.e
LIDDIFD03092012.TXT
The key part is to check the BUSINESS_DATE.TXT file is updated properly or not.
We don't know what time the file will get updated. So we are planning to schedule the new script to run for every 15 mins to check whether the file is updated or not.
is the above proposal is ok or is there any other feasible solution to do the same?

I think BUSINESS_DATE.TXT file having only one line that is date.

Means you can check for today's date..

Code:

$ date +%d%m%Y
03092012

Check if the file contains today's date or not after every 15 min.

any more inputs?

is it possible to create instance for a single script? My requirment is i need to run the same script for different countries. say for example, I have a input parameter called "CountryCode". If i pass, INDIA, The script needs to create an instance and should run. Parallely if i pass 'UK', the same script should create an instance for UK and should run. is it possible to create multiple instance for a shell script?

Yes. It is possible to create multiple instances of a single script but you have run it in background . Just give the input and run the script in background for your specific country code.

Something like this...

Code:

$sh Your_script.sh "India" &

$sh Your_script.sh "US" &

One small demo example ..
I have created one script which reads the input and print's it to the one file..
And got the desired output of all the three scripts..
Hope it helps..

Code:

$ cat file3.sh
a=$1
for (( i="$a";i>0;i--))
do
echo "$i" >> file_test
echo "$a" >> file_test
done

$sh file3.sh 11 &
sh file3.sh 8 &
sh file3.sh 6 &
