When you install an Oracle database in a Unix server, the Unix user id you use for the installation becomes the OWNER of the database. What is the most reliable and general way of determining in a shell script which Unix user is the owner of an Oracle installation? I mean, can you perform a grep on a file created by the installation to find this information or shall I resort to use the ls command on a specific file on a specific directory. If the name of the file to be checked is also variable, I would need to have a way of determining the name and path to the file.

Thanks in advance for your time
