Dive into the true power of the Linux shell. The Bash, Pipes, and Text Processing module transforms you from a basic navigator into a command-line wizard.

You will master standard input/output streams, learn to chain commands together using pipes, and wield the "power trio" of text processing (grep, awk, and sed) to parse massive log files and extract IOCs on the fly. By the end of this module, you will be able to build custom one-liners for threat hunting and understand how attackers manipulate shell profiles and environment variables for stealthy persistence.
