What is a parent directory what is a subdirectory?
Webopedia Staff. Refers to the directory above another directory. Every directory, except the root directory, lies beneath another directory. The higher directory is called the parent directory, and the lower directory is called a subdirectory.
What type of access does the execute permission for directories provide?
For directories, execute permission allows you to enter the directory (i.e., cd into it), and to access any of its files. Under both UFS and NFS, permissions exist separately for user, group, and others. User (u) permissions apply to the owner of the file.
Do the parent directory’s permissions matter when accessing a..?
The way you access a file matters. For example, if you have execute permissions on /foo/bar but not on /foo, but your current directory is /foo/bar, you can access files in /foo/bar through a relative path but not through an absolute path.
Do you have to give read permission to a directory?
Read permission on a directory gives the right to enumerate the entries. Giving execute permission without giving read permission is occasionally useful: the names of entries serve as passwords to access them. I can’t think of any use in giving read or write permission to a directory without execute permission.
How to grant access to sub folder when no access to parent folder?
As Dinesh Lakkaraju mentioned, you may share the subfolder so that users can directly access it without going through the parent folder. If you don’t want to share it, you can also: 1. Grant the users the READ permission on the parent folder (block inheritance to all subfolders and files).
Do you need execute permission to access a file?
So for example to access dir/subdir/file, you need execute permission on dir and dir/subdir, plus the permissions on file for the type of access you want. Getting into corner cases, I’m not sure whether it’s universal that you need execute permission on the current directory to access a file through a relative path (you do on Linux).
