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.
