SHELL Scripting Training

A shell script is nothing but a script written for command line interpreter of an operating system. The shell script is referred as simple domain-specific programming language. Shell script performs various operations such as program execution, file manipulation, and printing text.

DCL and JCL are the examples of the programming languages that are intended for shell scripting. Like batch files, in shell scripts, the commands are programmed in chains and they are executed as a scripting event by the system.

Apart from these, they also help to perform more useful functions like as command substitution. You are allowed to use programming functions like if/then/else statements, ‘for’ loops and so on, with your operating system directly.

Shell scripting is the right method that saves you time if you have a basic familiarity with UNIX® and you are in need to do more work. In a nutshell, the shell script is just a text file containing full of commands. The shell script must be executable.

One of the main advantages in using shell script is, it save lots of time. Interpreted language is used to write the shell script. The power for writing the shell script comes from the executing external programs to perform processing tasks.

With these, the performance of shell script can be limited. Since, they do not need any additional effort for execution, they are considered as a powerful tool for bootstrapping other kind of technologies. For example, autoconf tool is a chain of shell scripts, which is used for configuring software prior.
