The write permission grants the ability to modify a file. When set for a directory, this permission grants the ability to modify entries in the directory, which includes creating files, deleting files, and renaming files. This requires that execute is also set; without it, the write permission is meaningless for directories.
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.
Sets read and write permission for user, sets read for Group, and denies access for Others: chmod -R u+w,go-w docs: Adds write permission to the directory docs and all its contents (i.e. Recursively) for owner, and removes write permission for group and others chmod ug=rw groupAgreements.txt: Sets read and write permissions for user and Group
OneFS – One File System. This is a fully journaled, distributed file system used by Isilon. OneFS uses FlexProtect and Reed–Solomon encodings to support up to four simultaneous disk failures. OFS – Old File System, on Amiga. Good for floppies, but fairly useless on hard drives. OS-9 file system
A core security feature in these systems is the file system permissions. All files in a typical Unix filesystem have permissions set enabling different access to a file. Unix permissions permit different users access to a file with different privilege (e.g., reading, writing, execution). Like users, different user groups have different ...

the process has write permission for the file; the process has the P_OWNER privilege; If a 0410 a.out executable file has the sticky bit (mode bit 01000) set, the operating system will not delete the program text from the swap area when the last user process terminates. If a 0413 a.out or ELF executable file has the sticky bit set, the ...
In this matrix example there exist two processes, two assets, a file, and a device. The first process is the owner of asset 1, has the ability to execute asset 2, read the file, and write some information to the device, while the second process is the owner of asset 2 and can read asset 1.
