In computing, a symbolic link (also symlink or soft link) is a file whose purpose is to point to a file or directory (called the "target") by specifying a path thereto. [ 1 ] Symbolic links are supported by POSIX and by most Unix-like operating systems , such as FreeBSD , Linux , and macOS .
Since NTFS 3.1, a symbolic link can also point to a file or remote SMB network path. While NTFS junction points support only absolute paths on local drives, the NTFS symbolic links allow linking using relative paths. Additionally, the NTFS symbolic link implementation provides full support for cross-filesystem links.
The ln command is a standard Unix command utility used to create a hard link or a symbolic link (symlink) to an existing file or directory. [1] The use of a hard link allows multiple filenames to be associated with the same file since a hard link points to the inode of a given file, the data of which is stored on disk.
Symbolic links are immutable (they cannot be changed), however they can be removed and then a new symbolic link can be created in their place. Using the 'ls -l' command, which is standard on these systems, a symbolically linked file might look something like this: lrwxrwxrwx 1 jbailey users 4 2003-02-07 16:49 link -> file
Since 7 October 2024, Python 3.13 is the latest stable release, and it and, for few more months, 3.12 are the only releases with active support including for bug fixes (as opposed to just for security) and Python 3.9, [55] is the oldest supported version of Python (albeit in the 'security support' phase), due to Python 3.8 reaching end-of-life.
An NTFS reparse point is a type of NTFS file system object. It is available with the NTFS v3.0 found in Windows 2000 or later versions. Reparse points provide a way to extend the NTFS filesystem.
Python 2.6 was released to coincide with Python 3.0, and included some features from that release, as well as a "warnings" mode that highlighted the use of features that were removed in Python 3.0. [28] [10] Similarly, Python 2.7 coincided with and included features from Python 3.1, [29] which was released on June 26
A chmod command first appeared in AT&T Unix version 1, along with the chmod system call. As systems grew in number and types of users, access-control lists [3] were added to many file systems in addition to these most basic modes to increase flexibility. The version of chmod bundled in GNU coreutils was written by David MacKenzie and Jim ...
