LinuxCBT Awk & SedEdition focuses on the common Linux | Unix text transformation utilities: Awk & Sed.

Awk & Sed are critical to efficiently parsing textual data (log file contents, data feeds, file & directory listings, etc.). Awk provides field (Column) processing and reporting, whereas Sed facilitates streams (Automated Text Editing) processing. Both support interactive and non-interactive (scripted) execution.

Let LinuxCBT Awk & Sed Edition cost-effectively teach you automated field and streams processing.

Recommended Prerequisites for:

• Any LinuxCBT Operating System Course (Classic/EL-4/SUSE/Debian Editions)
  • Open mind & determination to master Linux and related open-source applications
  • Access to a Linux, Windows or GNU Awk & Sed-compatible system to follow the exercises
