General question on how to determine if a script ran in on a linux server.

The script is not running on a schedule.  It is called from another application.  How can I tell if it ran on the linux server.

Does the script do anything?  If so, that activity may leave a trace.
Does the application that called it record anything when it is called?
You can look at the last access time of the script, but it can be accessed without being called or running.

Yes the script does some checks.   However,  I can see in my application log that it should have called the script and I do not have an entry in the script log.

how do i see the last access time of the script.

What is a Denial of Service (DoS)?

A DoS is a malicious attempt to prevent the normal operation of a computer system. You may frequently see the terms 'DDoS' (Distributed Denial of Service) and 'DoS' used interchangeably, but there are some subtle differences.

Thanks.

Is there a limit to the number of times a shell script can be called or running at one time?

Normally one would have to quote a | character in order to pass it as an argument to a script, otherwise it is interpreted by the shell as sending the output of the XXXX command into the input of the CCCCCC  command.

Depending on what resources the processes consume, and what resources are available, there may be other limiting factors besides ulimit -u
