LinuxCBT RegEx Edition | 600 MB
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.
Let LinuxCBT RegEx Edition cost-effectively teach you Regular Expressions!
