Install and Manage Perl Packages on CentOS

Provides a tutorial example on how to install Perl 5.26 on CentOS 8 systems using 'dnf/yum' as the package manager.

The Perl (Practical Extraction and Report Language) script engine is included as part of the CentOS 8 system by default. You don't need to install it yourself. But you can still install its additional modules using the "dnf" package manager.

1. Login as "herong", who has admin privileges.

2. Check the current installed version of Perl:

herong$ perl -v

This is perl 5, version 26, subversion 3 (v5.26.3) built for
x86_64-linux-thread-multi (with 51 registered patches, ...)
...

3. Run "dnf info perl" to see Perl package information:

herong$ dnf info perl

Description  : Perl is a high-level programming language with roots in C, sed, awk and shell
             : scripting. Perl is good at handling processes and files, and is especially
             : good at handling text. Perl's hallmarks are practicality and efficiency.
             : While it is used to do a lot of different things, Perl's most common
             : applications are system administration utilities and web programming.
             :
             : This is a metapackage with all the Perl bits and core modules that can be
             : found in the upstream tarball from perl.org.
             :
             : If you need only a specific feature, you can install a specific package
             : instead. E.g. to handle Perl scripts with /usr/bin/perl interpreter,
             : install perl-interpreter package. See perl-interpreter description for more
             : details on the Perl decomposition into packages.

4. Install the "perl" package:

herong$ sudo dnf install perl

...
