Check if file exists

I need to check whether a file exists and has been changed.



The file should contain a specific string. The file should also have been changed within the last ten seconds.


How do I do that?

We need to know what UNIX you have and what shell you use. The answers would be all over the place without that information. Thanks.

Yes, and please follow forum rules and search the forums before asking questions.

Code:
Showing results 1 to 25 of 1218

This question has been asked and answered countless times. This is why we have a long standing forum rule:
