Shell Programming and Scripting

1. Shell script should poll the directory  everyday at 3pm for 2 files a.csv and a.dat. It should poll the  directory for the files for only 15 mins after that it should error out  saying that no files received.
2. After receving the first file ( the order of the file doesnt  matter) it should wait for max 5 mins. if second file not recieved then  throw an error saying that the other file is not received.
3. Only after both the files are received then the shell script  should copy the a.csv file to another directory and wait for 1 min
4.  After 1 MIN copy a.dat to another directory and after successful copy  archive the files with a current timestamp to another directory
