I know there is a command that I forgot if you erase a active log file it still holds the diskspace how do I release the space.

did a cat >> /logfile name. I need to release it. Help.

The space allocated to a deleted file will remain taken until all file handles on it are closed.

Short version: kill the process that has the file open.
