CU011 - UNIX Tools
Length: 3 Days
In this course the attendee will learn how to use
more than 50 UNIX commands and their various options and
will then be able to interface them together using shell
programming constructs. This is an extensive hands-on course and
is supported by the excellent UNIX Desktop Guide to Tools
textbook by Peter Holsberg. Attendees are encouraged to bring
example problems to class so they can be assisted with developing
correct solutions. The overall objective of this course is to
provide the attendee with the knowledge about UNIX
commands so that they can select the appropriate commands for
many types of data processing applications.
Upon completion of this course the attendee will be able to:
- state the UNIX "tool" philosophy;
- construct and use regular expressions;
- select, format, and process data selected from specified files;
- display and print information from files;
- use the sed command to apply editing commands to files from an input stream;
- use the awk programming language to scan files and process patterns;
- use the commands learned in the course to interact with the shell to create user tools for information processing.
