I have two files with apparently the same name in a Unix directory. How is this possible? When I used the -b option with ls, it is giving a different name. The duplicate file is automatically created after sap kernel upgrade. The backup of the old kernel of SAP was placed inside PP2 directory before performing the upgrade by creating a separate folder for it. Does anybody know the reason behind this?
Details are as follows:
