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).
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 ...
For example, to add simple documentation to bash scripts, which can then be easily converted to man pages. [1] Such uses rely on language-specific hacks to hide the pod part(s), such as (in bash) prefixing the POD section with the line :<<=cut which works by calling bash's no-op : command, with the whole block of Pod as a here document as input ...
The second line in the canonical form includes a semicolon, which is used to separate statements in Perl. With only a single statement in a block or file, a separator is unnecessary, so it can be omitted from the minimal form of the program—or more generally from the final statement in any block or file.
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.
