An object file is an intermediate file used in the building of an executable file.The Dos2unix package includes utilities dos2unix and unix2dos to convert plain text files in DOS or Mac format to Unix format and vice versa. The name shared object is used only in Unix-like systems, such as Linux, BSD and Mac OS X. This can be a program file or a dynamic link library, also called shared object. 1.1 File types An executable file is a file containing machine code that can be executed.

After the script file has been made an executable with the chmod command.CoffeeScript, Groovy, JavaScript, Julia, LPC, PHP, Python, Raku, Ruby, PowerShellPerl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. Thus, to convert the Ctrl-m of a Mac OS text file to the line feed (Ctrl-j) of a Unix text file, at the Unix command line, enter: tr ' ' ' ' < macfile.txt > unixfile.txtAWK, BASIC, C, C++, Lisp, sed, Unix shell In other versions of Unix or Linux, this will not run the. Characters specified in one set are converted to the matching character in the second set.

In addition to CGI, Perl 5 is used for system administration, network programming, finance, bioinformatics, and other applications, such as for GUIs. Perl 5 gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its unsurpassed regular expression and string parsing abilities. Both languages continue to be developed independently by different development teams and liberally borrow ideas from each other.The Perl languages borrow features from other programming languages including C, shell script ( sh), AWK, and sed They provide text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools.

Wall discovered the existing PEARL programming language before Perl's official release and changed the spelling of the name. Wall wanted to give the language a short name with positive connotations. Perl was originally named 'Pearl'. Perl is a highly expressive programming language: source code for a given algorithm can be short and highly compressible. In 1998, it was also referred to as the ' duct tape that holds the Internet together,' in reference to both its ubiquitous use as a glue language and its perceived inelegance.

Schwartz, however, capitalized the language's name in the book to make it stand out better when typeset. Before the release of the first edition of Programming Perl, it was common to refer to the language as perl. When referring to the program itself, the name is uncapitalized ( perl) because most Unix-like file systems are case-sensitive.

Perl 3, released in 1989, added support for binary data streams. The language expanded rapidly over the next few years.Perl 2, released in 1988, featured a better regular expression engine. History Early versions Larry Wall began work on Perl in 1987, while working as a programmer at Unisys, and version 1.0 was released to the comp.sources.unix newsgroup on February 1, 1988. The name is occasionally expanded as a backronyms: Practical Extraction and Report Language and Wall's own Pathologically Eclectic Rubbish Lister which is in the manual page for perl.

It remains the primary forum for development, maintenance, and porting of Perl 5. The perl5-porters mailing list was established in May 1994 to coordinate work on porting Perl 5 to different platforms. Initial design of Perl 5 continued into 1994. Early Perl 5 Perl 4 went through a series of maintenance releases, culminating in Perl 4.036 in 1993, whereupon Wall abandoned Perl 4 to begin work on Perl 5. At the same time, the Perl version number was bumped to 4, not to mark a major change in the language but to identify the version that was well documented by the book. In 1991, Programming Perl, known to many Perl programmers as the 'Camel Book' because of its cover, was published and became the de facto reference for the language.

Perl 5.002 was released on Februwith the new prototypes feature. Perl 5.001 was released on March 13, 1995. Perl 5 has been in active development since then. This allowed the core interpreter to stabilize, even as it enabled ordinary Perl programmers to add new language features. Importantly, modules provided a mechanism for extending the language without modifying the interpreter. It was a nearly complete rewrite of the interpreter, and it added many new features to the language, including objects, references, lexical (my) variables, and modules.

Another significant development was the inclusion of the CGI.pm module, which contributed to Perl's popularity as a CGI scripting language. Perl 5.004 was released on May 15, 1997, and included, among other things, the UNIVERSAL package, giving Perl a base object from which all classes were automatically derived and the ability to require versions of modules. On October 26, 1995, the Comprehensive Perl Archive Network (CPAN) was established as a repository for the Perl language and Perl modules as of May 2017, it carries over 185,178 modules in 35,190 distributions, written by more than 13,071 authors, and is mirrored worldwide at more than 245 locations. One of the most important events in Perl 5 history took place outside of the language proper and was a consequence of its module support. Perl 5.003 was released June 25, 1996, as a security release.

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 versions to have odd numbers and stable versions to have even numbers. Major changes included 64-bit support, Unicode string representation, support for files over 2 GiB, and the 'our' keyword. 2000вЂ“2020 Major version Older version, yet still maintained: 5.32Latest preview version of a future release: 5.35Perl 5.6 was released on March 22, 2000. This release included several enhancements to the regex engine, new hooks into the backend through the B::* modules, the qr// regex quote operator, a large selection of other new core modules, and added support for several more operating systems, including BeOS. Perl 5.005 was released on July 22, 1998.

They were presented as a digest of the RFCs, rather than a formal document. In 2001, work began on the 'Apocalypses' for Perl 6, a series of documents meant to summarize the change requests and present the design of the next generation of Perl. The process resulted in 361 RFC (request for comments) documents that were to be used in guiding development of Perl 6.
