A guide to a carefully designed subset of the Perl language,
this book makes Perl more accessible to those having UNIX/Linux
skill levels ranging from elementary to expert by capitalizing on
their existing knowledge of important utilities (grep, awk), or
essential concepts (filters, command substitution, looping). Dozens
of detailed programming examples are shown, drawn from contemporary
application areas such as system administration, networking, Web
development, databases, finance, HTML, CGI, and text analysis.
Broken into two parts, the first is for all who are familiar with
core UNIX/Linux commands such as grep and caters to readers ranging
from managers and administrative staff to advanced programmers. The
second part is for developers experienced in Bourne, Korn, Bash, or
POSIX Shell programming and makes Perl scripting easy to learn by
showing Shell examples along with their Perl counterparts. Many
Perl modules are covered including freely available pre-written
code from the CPAN.
