There are 3 really powerful tools that every Linux / UNIX professional should know: grep, SED, and AWK.
Our grep, SED and AWK Best Practices training course will give you hands-on experience with all three.
grep is accessed via the command-line and is used for querying plain-text data sets using regular expressions.
SED (short for stream editor) is used for parsing and sequentially applying transformations to text.
AWK is a data extraction and reporting tool, controlled by a scripting language for producing formatted reports.
