| | Symbolic link - Wikipedia, the free encyclopedia |
 | | In computing, a symbolic link (often shortened to symlink) is a special type of file that serves as a reference to another file. | | | As a result, symbolic links can be used to refer to files on other mounted file systems. | | | This space is generally used for storing the chain of disk blocks composing a file (60 bytes on the Unix File System). |

| | Hard link - Wikipedia, the free encyclopedia |
| | In computing, a hard link is a reference, or pointer, to physical data on a storage volume. | | | If all of the links are removed and no process has the file open, then the space occupied by the data will be considered free, allowing it to be reused in the future for other files. | | | It is also the simplest way for the file system to track the use of a given area of storage, as zero values indicate free space and nonzero values indicate used space. |

| | Using symbolic links |
| | Therefore, when evaluating a pathname, it is important to put a limit on the number of symbolic links that may be encountered in case the evaluation encounters a loop. | | | where sym is a symbolic link that references a regular file foo, and file1 is a regular file, file1 is overwritten and hard-linked to foo. | | | This kind of symbolic link may be used when files exist in the directory /usr/src/uts/sys but programs often refer to files in /usr/include/sys. |

| | symlink()--Make Symbolic Link |
| | If the symbolic link is not the last component of the original path name, remaining components of the original path name are resolved relative to the symbolic link. | | | When a component of a path name refers to a symbolic link rather than to a directory, the path name contained in the symbolic link is resolved. | | | This error is issued if the number of symbolic links encountered is more than POSIX_SYMLOOP (defined in the limits.h header file). |

| | Symbolic link |
| | Also known as a SYLK, a symbolic link was developed by Microsoft and is an ASCII formatted file that is saved with a.slk file extension and enables the exchange of information contained in Microsoft Excel spreadsheets with other programs. | | | Also known as a soft link or symlink, a symbolic link is a Linux / Unix file created with the ln command that links to another file using the path. | | | Unlike a hard link, a symbolic link can link to any file on any computer. |

| | :: Shell-Shocked :: Windows Symbolic and Hard Links |
| | Hard links are unbreakable, for example; because the information you see in your file browser, such as the file name, is stored in the filesystem table, and not at the disk address referenced in the filesystem table, this information can be changed at will without risk of affecting that link or any other link. | | | In a nutshell, symbolic links are files that contain a path to another file or folder (or maybe something else) somewhere else on your hard drive; and anything trying to read or write the link will automatically read or write the resource to which the link points. | | | Windows hard links, from what I've read, behave pretty much like hard links in UNIX and Linux: they can only be used for files, and they cannot cross disk volume or file system boundaries; all hard links to a disk address must reside in the same partition as the disk address itself. |
