プログラミング言語のPerlの標準のモジュールとコマンド (ユーティリティ) に何が存在するのか気になったので調査した。

2019-03-24時点で最新版のPerl 5.26.1について,Perlの公式文書サイトであるperldoc.perl.orgから,以下のページのリストを整理した。

特に,標準モジュール (Core modules) はアルファベットごとにページが分かれており,一覧性や検索性が悪かったので,単一の表にまとめておきたかった。

調べた結果,コマンド (Perlインタープリター+ユーティリティ) は全部で29個あり,標準モジュールは393個存在した。

標準コマンドでは,perl, perldoc, cpanが特に重要だと感じた。その中でも,cpanはPerlのパッケージマネージャーであるので,モジュールの追加インストールで頻繁に使うことになるだろう。



Perl 5.26.1標準コマンド一覧
分類 コマンド 説明
Interpreter perl The Perl 5 language interpreter.
Documentation perldoc The main interface to Perl’s documentation is perldoc , although if you’re reading this, it’s more than likely that you’ve already found it. perldoc will extract and format the documentation from any file in the current directory, any Perl module installed on the system, or any of the standard documentation pages, such as this one. Use perldoc <name> to get information on any of the utilities described in this document.
Documentation pod2man, pod2text If it’s run from a terminal, perldoc will usually call pod2man to translate POD (Plain Old Documentation – see perlpod for an explanation) into a manpage, and then run man to display it; if man isn’t available, pod2text will be used instead and the output piped through your favourite pager.
Documentation pod2html As well as these two, there is another converter: pod2html will produce HTML pages from POD.
Documentation pod2usage If you just want to know how to use the utilities described here, pod2usage will just extract the “USAGE” section; some of the utilities will automatically call pod2usage on themselves when you call them with -help.
Documentation podselect pod2usage is a special case of podselect, a utility to extract named sections from documents written in POD. For instance, while utilities have “USAGE” sections, Perl modules usually have “SYNOPSIS” sections: podselect -s “SYNOPSIS” … will extract this section for a given file.
Documentation podchecker If you’re writing your own documentation in POD, the podchecker utility will look for errors in your markup.
Documentation splain splain is an interface to perldiag – paste in your error message to it, and it’ll explain it for you.
Documentation roffitall The roffitall utility is not installed on your system but lives in the pod/ directory of your Perl source kit; it converts all the documentation from the distribution to *roff format, and produces a typeset PostScript or text file of the whole lot.
Converters pl2pm To help you convert legacy programs to more modern Perl, the pl2pm utility will help you convert old-style Perl 4 libraries to new-style Perl5 modules.
Administration libnetcfg To display and change the libnet configuration run the libnetcfg command.
Administration perlivp The perlivp program is set up at Perl source code build time to test the Perl version it was built under. It can be used after running make install (or your platform’s equivalent procedure) to verify that perl and its libraries have been installed correctly.
Development perlbug perlbug is the recommended way to report bugs in the perl interpreter itself or any of the standard library modules back to the developers; please read through the documentation for perlbug thoroughly before using it to submit a bug report.
Development perlthanks This program provides an easy way to send a thank-you message back to the authors and maintainers of perl. It’s just perlbug installed under another name.
Development h2ph Back before Perl had the XS system for connecting with C libraries, programmers used to get library constants by reading through the C header files. You may still see require ‘’ or similar around – the .ph file should be created by running h2ph on the corresponding .h file. See the h2ph documentation for more on how to convert a whole bunch of header files at once.
Development h2xs h2xs converts C header files into XS modules, and will try and write as much glue between C libraries and Perl modules as it can. It’s also very useful for creating skeletons of pure Perl modules.
Development enc2xs enc2xs builds a Perl extension for use by Encode from either Unicode Character Mapping files (.ucm) or Tcl Encoding Files (.enc). Besides being used internally during the build process of the Encode module, you can use enc2xs to add your own encoding to perl. No knowledge of XS is necessary.
Development xsubpp xsubpp is a compiler to convert Perl XS code into C code. It is typically run by the makefiles created by ExtUtils::MakeMaker.
xsubpp will compile XS code into C code by embedding the constructs necessary to let C functions manipulate Perl values and creates the glue necessary to let Perl access those functions.
Development prove prove is a command-line interface to the test-running functionality of Test::Harness. It’s an alternative to make test .
Development corelist A command-line front-end to Module::CoreList , to query what modules were shipped with given versions of perl.
General tools piconv piconv is a Perl version of iconv, a character encoding converter widely available for various Unixen today. This script was primarily a technology demonstrator for Perl v5.8.0, but you can use piconv in the place of iconv for virtually any case.
General tools ptar ptar is a tar-like program, written in pure Perl.
General tools ptardiff ptardiff is a small utility that produces a diff between an extracted archive and an unextracted one. (Note that this utility requires the Text::Diff module to function properly; this module isn’t distributed with perl, but is available from the CPAN.)
General tools ptargrep ptargrep is a utility to apply pattern matching to the contents of files in a tar archive.
General tools shasum This utility, that comes with the Digest::SHA module, is used to print or verify SHA checksums.
General tools zipdetails zipdetails displays information about the internal record structure of the zip file. It is not concerned with displaying any details of the compressed data stored in the zip file.
Installation cpan cpan is a command-line interface to It allows you to install modules or distributions from CPAN, or just get information about them, and a lot more. It is similar to the command line mode of the CPAN module,
perl -MCPAN -e shell
Installation instmodsh A little interface to ExtUtils::Installed to examine installed modules, validate your packlists and even create a tarball from an installed module.
