There exists a folder in my system with a number of files in it. SYST is a user of the folder with all permissions. SYST had access to all files of the folder. But somehow, now there exists no user named SYST for a number of files in the folder.
How can I grant access permission for SYST to these files in the folder. Granting permission individually to each file is a tedious task.
Is there any other method apart from using icacls?
