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).
A pod parser always assumes that the file it is parsing doesn't start with pod; it ignores all lines until it sees a pod directive. pod directives must come at the beginning of a line, and all begin with an equal sign. The pod parser will then assume that all following lines are pod, until it encounters a line consisting of the "=cut" directive.
Major changes included 64-bit support, Unicode string representation, support for files over 2 GiB, and the "our" keyword. [ 46 ] [ 47 ] When developing Perl 5.6, the decision was made to switch the versioning scheme to one more similar to other open source projects; after 5.005_63, the next version became 5.5.640, with plans for development ...
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.
An n-component link L ⊂ S 3 is an unlink if and only if there exists n disjointly embedded discs D i ⊂ S 3 such that L = ∪ i ∂D i. A link with one component is an unlink if and only if it is the unknot. The link group of an n-component unlink is the free group on n generators, and is used in classifying Brunnian links.
