Shell Programmierung für Systemadministratoren

Description

The Shell Programming for System Administrators course provides students with the skills to read, write, and debug
UNIX shell scripts. The course begins by describing simple scripts to automate frequently executed commands and
continues by describing conditional logic, user interaction, loops, menus, traps, and functions. This course is intended
for system administrators who have mastered the basics of a UNIX Operating Environment (OE) such as the Solaris OE
or Linux and who would like to read and understand the various boot scripts and write their own scripts to automate their
day-to-day tasks. This course explores, in detail, the Bourne and Korn shell scripting languages.
