全面讲解与POSIX、Perl兼容的正则表达式的使用和应用！

LinuxCBT RegEx Edition focuses on the application of POSIX and Perl-compatible Regular Expressions.

Regular Expressions are critical to efficiently parsing textual data (log file content, data feeds, files & directories, etc.). RegEx support is included with Linux | Unix operating systems via ubiquitous tools such as: grep, awk, sed, Perl, PHP, etc., and provides systems administrator/engineers and developers alike, the ability search, time-effectively, considerable amounts of textual data, using literals, character classes, metacharacters, metasequences, etc.
