| + | ===== Simple Permissions ===== | ||
| + | The rows of checkboxes are used to set/unset specific permissions for the //Owner// (the owner of the file); the //Group// (members of file group); and //Others// (all others). The label //R// stands for "read permissions for file (or folder)", //W// for "write" and //X// for "execute". For directories the "execute permission" means permission to enter the directory (make it working directory). | ||
| + | ===== [[special]] Special Permissions ===== | ||
| + | There are three special permissions. //Set UID// and //Set GID// are used with executable files. They grant the user, who executes the file, permissions of file owner or group, respectively. //Sticky bit// for executable files makes the kernel keep the memory image of the process after it has terminated, in order to avoid the overhead of reloading it when it is re-invoked. //Sticky bit// for directories ensures that only the owner of a file can remove or delete the file or directory. | ||
