Perl (very basics)

PERL is an open source language so there’s a huge amount of info published on the internet. Check out perl.org for starters. Here’s some starter info:
1) PERL is an interpreted language. That means the PERL engine reads and then executes your entire script at runtime. The code is usually not compiled and saved as machine code.
2) PERL is typically used to parse (read) files and output formatted text reports. There’s a common interface called CGI that lets you pass text streams between PERL and web servers.
3) List processing is common in PERL. There are mode advanced data types, but you can do whole lot with lists only.
4) Regular expressions is a pattern-recognition language used in PERL, C, Unix, SED, Awk and other languages. It’s very useful for parsing incoming streams of text.
