Linux Shell Scripting

Linux Shell Scripting training | KR Network Cloud

Shell script defined as: “Shell Script is series of command written in plain text file. Shell script is just like batch file is MS-DOS but have more power than the MS-DOS batch file.”

Normally shells are interactive. It means shell accept command from you (via keyboard) and execute them. But if you use command one by one (sequence of 'n' number of commands), then you can store this sequence of command to text file and tell the shell to execute this text file instead of entering the commands. This is known as shell script.

Linux Shell Scripting Course Objective

Shell scripts can be used to prepare input files, job monitoring, and output processing.

  • Useful to create own commands.
  • Save lots of time on file processing.
  • To automate some task of day to day life.
  • System Administration part can be also automated.
  • A working knowledge of shell scripting is essential to everyone wishing to become
  • reasonably adept at system administration, even if they do not anticipate ever having to actually write a script.
  • Writing shell scripts is not hard to learn, since the scripts can be built in bite-sized sections and there is only a fairly small set of shell-specific operators and options to learn.
  • The syntax is simple and straightforward, similar to that of invoking and chaining together utilities at the command line, and there are only a few "rules" to learn.
  • A shell script is a "quick and dirty" method of prototyping a complex application

Why Learn Linux Shell Scripting?

What is Shell?

  • It is a command language interpreter that executes commands read from the standard input device such as keyboard or from a file.
  • The shell gets started when you log in or open a console (terminal).
  • Quick and dirty way to execute utilities.

The shell is not part of system kernel, but uses the system kernel to execute programs, create files etc.

What is Kernel?

  • Kernel is hart of Linux Os.
  • It manages resource of Linux Os. Resources means facilities available in Linux. For e.g. Facility to store data, print data on printer, memory, file management etc.
  • Kernel decides who will use this resource, for how long and when. It runs your programs (or set up to execute binary files).
  • The kernel acts as an intermediary between the computer hardware and various programs/application/shell.
