There is some contention about the all-caps spelling "Perl", which the documentation declares incorrect and which some core community members consider a sign of outsiders. This case distinction was subsequently documented as canonical. 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 Randal L. When referring to the interpreter program itself, the name is often uncapitalized (perl) because most Unix-like file systems are case-sensitive. When referring to the language, the name is normally capitalized (Perl) as a proper noun. Wall discovered the existing PEARL programming language before Perl's official release and changed the spelling of the name. He also considered naming it after his wife Gloria. Larry Wall wanted to give the language a short name with positive connotations he claims that he considered (and rejected) every three- and four-letter word in the dictionary. Perl was originally named "Pearl", after the Parable of the Pearl from the Gospel of Matthew. It is also referred to as the "duct tape that holds the Internet together", in reference to its ubiquity and perceived inelegance.
Perl is nicknamed "the Swiss Army chainsaw of programming languages" due to its flexibility and power. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications. Perl gained widespread popularity in the late 1990s as a CGI scripting language, in part due to its parsing abilities. The language provides powerful text processing facilities without the arbitrary data length limits of many contemporary Unix tools, facilitating easy manipulation of text files. Perl borrows features from other programming languages including C, shell scripting (sh), AWK, and sed. Larry Wall continues to oversee development of the core language, and its upcoming version, Perl 6. Since then, it has undergone many changes and revisions and become widely popular amongst programmers. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier.

The patch number is usually omitted in discussions of Perl versions.Perl is a high-level, general-purpose, interpreted, dynamic programming language. 5.36) are stable releases, and odd numbers are experimental development versions. Release numbers use semantic versioning since 5.6, where even-numbered minor versions (e.g. Note that Perl Maintenance and Support Policy is to "support the two most recent stable release series". Additional information can be found on the official Perl website. Note that additional minor release versions are not shown in this chart, unless they include notable changes or are the latest supported version. The following table contains the Perl 5 version history, showing its release versions.
Perl is an open-source programming language whose first version, 1.0, was released in 1987.
