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 .
A symbolic link is a reference to another file. This special file is stored as a textual representation of the referenced file's path (which means the destination may be a relative path, or may not exist at all). A symbolic link is marked with an l (lower case L) as the first letter of the mode string, e.g. in this abbreviated ls -l output: [5]
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree. [21]
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.
The filesystem appears as one rooted tree of directories. [1] Instead of addressing separate volumes such as disk partitions, removable media, and network shares as separate trees (as done in DOS and Windows: each drive has a drive letter that denotes the root of its file system tree), such volumes can be mounted on a directory, causing the volume's file system tree to appear as that directory ...
Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/realdir pwd -L: Display the current working directory logical path - with symbolic link name, if any. Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/symlinked
The inode number pointed to by this symlink is the same for each process in this namespace. This uniquely identifies each namespace by the inode number pointed to by one of its symlinks. Reading the symlink via readlink returns a string containing the namespace kind name and the inode number of the namespace.
Changes the permissions of a file or directory cp: Copies a file or directory dd: Copies and converts a file df: Shows disk free space on file systems dir: Is exactly like "ls -C -b". (Files are by default listed in columns and sorted vertically.) dircolors: Set up color for ls: install: Copies files and set attributes ln: Creates a link to a ...
