The effect of setting the permissions on a directory, rather than a file, is "one of the most frequently misunderstood file permission issues". [10] When a permission is not set, the corresponding rights are denied. Unlike ACL-based systems, permissions on Unix-like systems are not inherited. Files created within a directory do not necessarily ...
The setuid permission set on a directory is ignored on most UNIX and Linux systems. [5] [citation needed] However FreeBSD can be configured to interpret setuid in a manner similar to setgid, in which case it forces all files and sub-directories created in a directory to be owned by that directory's owner - a simple form of inheritance. [6]
Windows PowerShell, which has become a component of Windows 7 and later, features two commands that can read and write attributes: Get-ItemProperty and Set-ItemProperty. [10] To change an attribute on a file on Windows NT, the user must have appropriate file system permissions known as Write Attributes and Write Extended Attributes. [11]
Similarly, only a member of a group can change a file's group ID to that group. [1] The version of chown bundled in GNU coreutils was written by David MacKenzie and Jim Meyering. [2] The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities. [3]
If a script is invoked as an argument to the interpreting shell, it will be executed regardless of whether the user holds the execute permission for that script. Although Windows also specifies an execute permission, none of the Windows-specific shells block script execution if the permission has not been granted.
A directory whose "sticky bit" is set becomes a directory in which the deletion of files is restricted. A file in a sticky directory may only be removed or renamed by a user if the user has write permission for the directory and the user is the owner of the file, the owner of the directory, or the super-user.
The filesystem appears as one rooted tree of directories. [1] Instead of addressing separate volumes such as disk partitions, removable media, and network shares as separate trees (as done in DOS and Windows: each drive has a drive letter that denotes the root of its file system tree), such volumes can be mounted on a directory, causing the volume's file system tree to appear as that directory ...
