Perl is ideal for text manipulation
It should come as no surprise that text manipulation is Perl's most popular usage. For over three decades, Perl has been the go-to language for regex, HTML parsing, JSON manipulation, and other tasks. Simply said, no other programming language offers more powerful or user-friendly text manipulation tools.
Perl is ideal for log management
Because of the extent to which current computer systems have grown dispersed, as well as the way they blend so many different sorts of components (each with its own logging method), modern log management has become a science in and of itself. Perl is quite useful for interacting with most log management solutions, from standards like syslog to bespoke systems like Papertrai.
Of course, you may create your own Perl scripts for aggregating and analyzing logs, which is beneficial in cases when a fully customized log management solution is required.
System administration tasks are scripted in Perl
Perl has long had a significant following in the Unix/Linux environment, where administrators frequently use it to script routine system management chores. However, Perl may also be useful in Windows-centric contexts. Perl allows you to communicate with Active Directory and even the Windows registry.
Do you need to keep track of what software is installed on your users' computers? Or should periodic updates/maintenance be performed when the system boots? Perl may be the ideal approach to script such administrative chores on both Windows and Linux.
TAP for Software Testing
If you wish to deploy software on a continuous and automated basis, you must likewise test it on a continuous and automated basis. Perl provides numerous best-in-class testing methods, beginning with the most well-known and extensively used Test Anything Protocol, often known as TAP::Harness.
