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.

  • Delegates should have a good working knowledge of Linux or UNIX systems, which includes a working knowledge of UNIX commands and utilities. This can be gained by attending our UNIX Fundamentals or Linux Essentials courses
  • Delegates should also have a practical understanding of programming concepts such as variables, and decision-making constructs.

At the end of this course you will be able to:

  • Use all significant features of the BASH language
  • Implement advanced variable and array manipulation
  • Develop shell scripts that contain advanced decision making constructs
  • Use the tracing features to speed the development of shell scripts

Mastering Bash Scripts Training Course in Denmark

Denmark is a constitutionally unitary state that is in Northern Europe. The population of the country is 5.91 million and 800,000 of them live in the capital and largest city, Copenhagen. And Danish is the official language. Denmark is a part of Scandinavia, like Norway and Sweden. The country experiences changeable weather, since it's located in the meeting point of diverse air masses. The coldest month of Denmark is February while July is the warmest month.

The most popular tourist attractions are Tivoli Gardens, Nyhavn, Kronborg Slot and Viking Ship Museum. Tivoli is considered as the inspiration behind the Disney theme parks, which also contains roller coasters, puppet theaters, restaurants and food pavilions. And the reason why Kronborg Slot attracts tourists is because the castle is the setting of Shakespeare's Hamlet, and also a UNESCO World Heritage Site.

With a focus on meeting the unique requirements of Denmark, Bilginç IT Academy integrates advanced training methodologies into our diverse range of Certification Exam preparation courses and accredited corporate training programs. Prepare to revolutionize your perception of IT training with us.
