SUMMARY:Using Regular Expressions with Linux Tools (COMPLECS)
DESCRIPTION:Regular expressions (regexes) provide a way to identify strings
  that match a specified pattern. They are extremely useful for preprocessi
 ng text and extracting results from high-performance computing and data sc
 ience workloads. Primarily in the context of the Linux grep utility, we in
 troduce the main features of regular expressions (regexes) incrementally: 
 string literals, specifying multiple characters, quantifiers, wildcards, a
 nchors, character classes, grouping, and alternation. We also explore more
  advanced topics, such as word boundaries, lazy and greedy matching, regex
  flavors (basic, extended, and Perl-compatible), regexes with awk and sed,
  searching compressed files, and utilizing large language models (LLMs) to
  create regexes.A working knowledge of grep, and optionally awk and sed, w
 ill help you make the most of this session. We recommend attending the COM
 PLECS Linux tools for file processing webinar or reviewing the associated 
 materials (recording, slides, GitHub repo) if you are not familiar with th
 ese topics.
