This is the fourth thread ...

1. Creating multiple files and writing in each file
2. reboot a system (machine or server) multiple times with perl script
3. Create a folder/file and reboot the machine and check for the created file/folder on the location.
4. a perl program to create two way connection with the server

... for what I think is exactly the same problem, and still it smells like an XY problem. Please explain what you really try to do, stay in one thread, and don't open new threads for every new minor issue. That wastes everyone's time.
