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 ...
Outline of Perl – overview of and topical guide to the Perl programming language; Raku – Perl 5's sister language; man page – form of software documentation usually found on a Unix or Unix-like operating system, invoked by issuing the man command. Perl documentation is sometimes available as man pages.
The following outline is provided as an overview of and topical guide to the Perl programming language: Perl – high-level, general-purpose, interpreted, multi-paradigm, dynamic programming language. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. [1]
Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language for the Web, in part due to its parsing abilities. [15] Python is a widely used general-purpose, high-level, interpreted, programming language. [16] Python supports multiple programming paradigms, including object-oriented, imperative, functional and procedural ...
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. The command is also available in the ...
For example, Windows Vista users must manually indicate when creating a symbolic link whether it is a file or a directory. [17] Windows 7 and Vista support a maximum of 31 reparse points (and therefore symbolic links) for a given path (i.e. any given path can have at most 31 indirections before Windows gives up). [18]
In July 2000, the third edition of Programming Perl was published. This version was again rewritten, this time by Wall, Christiansen and Jon Orwant, and covered the Perl 5.6 language. [2] [3] The fourth edition constitutes a major update and rewrite of the book for Perl version 5.14, and improves the coverage of Unicode usage in Perl. The ...
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.
