This course deals comprehensively with the capabilities of BASH and the utilities commonly used in the development of scripts. The training concentrates on a common approach to BASH on variants of UNIX, and currently covers versions of BASH up to 4.1.

Target Audience:

The course is aimed at programmers and analysts operating in Unix environments using BASH, as well as Unix system and network managers. This course is particularly suitable for those companies, which take a multi-vendor open systems view, and is applicable to all flavours of UNIX including Linux, HP-UX, Solaris, AIX, and so on.
