Polling/Interrogate Directory Questions
Hello, need some ideas on the control statement for a script that will watch a directory, looking for any duplicate records as they are added.
I was thinking about a process that would watch the dir in a time window. Whenever a new line or entry was made I would grep the existing file for any exact lines that match.
Not sure about how to do this, maybe check on " ls | wc -l " or something similiar. Not sure about the control logic, while loop or a for statement.
Any ideas would be appreciated.
thanks, david
