In Unix-like operating systems, unlink is a system call and a command line utility to delete files. The program directly interfaces the system call, which removes the file name and (but not on GNU systems) directories like rm and rmdir. [1] If the file name was the last hard link to the file, the file itself is deleted as soon as no program has ...
Perl Programming Documentation, also called perldoc, is the name of the user manual for the Perl 5 programming language. It is available in several different formats, including online in HTML and PDF. The documentation is bundled with Perl in its own format, known as Plain Old Documentation (pod).
Instead, it is read with the perldoc tool, or converted into Unix man pages or Web-standard HTML pages. It is also possible to use pod in other contexts than Perl. For example, to add simple documentation to bash scripts , which can then be easily converted to man pages. [ 1 ]
The Hopf link is a simple example of a link with two components that is not an unlink. The Borromean rings form a link with three components that is not an unlink; however, any two of the rings considered on their own do form a two-component unlink. Taizo Kanenobu has shown that for all n > 1 there exists a hyperbolic link of n components such ...
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 .
rm (short for remove) is a basic command on Unix and Unix-like operating systems used to remove objects such as computer files, directories and symbolic links from file systems and also special files such as device nodes, pipes and sockets, similar to the del command in MS-DOS, OS/2, and Microsoft Windows.
If the link is unsolvable - that is, if the context provided on the page leaves no cues from which it can be solved, and a search of external sources provides no help - consider whether the link is necessary to the page at all. It is perfectly acceptable to unlink a term if the link itself serves no encyclopedic purpose.
There are also functions for producing HTML or XHTML output, but these are now unmaintained and are to be avoided. [1] CGI.pm was a core Perl module but has been removed as of v5.22 of Perl. [ 1 ] The module was written by Lincoln Stein and is now maintained by Lee Johnson.
