Programming

Hello,

I currently have a system that is running and writing to a log file. Every month I run a rollLogs script that moves this file to a different location and creates a new file in the original location. The service that is writing to this log is running when i run this script and it still has its FileHandle pointing to the old file. The program continues to write to the moved file instead of the new file.

Is there a way to redirect the output of a file to the newly created log file without having to restart the program?

Thanks for the help
Andy

See the dup2() manpage...assuming it's a C program

Code:

dup2(fd_of_new_file, fd_of_old_file);

Thanks for the response shamrock. I looked into it but was still unable to get this working. Im using PERL and the POSIX module has a dup2() that is suppose to mimic the c function.

Is there any easy way to determine the File Desc of the old log file? I was hoping i could just enter the path of the oldfile and the path of the new and the function would take care of the rest.

Thanks again for the help

I think you can do your job in another way.
Copy old file to a new location, after that empty the original file.
But there are chances of data loss, if the service writes log between copying and emptying.
