Writing a Bash Shell Script

What Are Shell Scripts? In the simplest terms, a shell script is a file containing a series of commands. The shell reads this file and carries out the commands as though they have been entered directly on the command line. The shell is somewhat unique, in that it is both a powerful command line interface to the system and a scripting language interpreter. As we will see, most of the things that can be done on the command line can be done in scripts, and most of the things that can be done in scripts can be done on the command line. Writing Your First Script And Getting It To Work To successfully write a shell script, you have to do three things: Write a script Give the shell permission to execute it Put it somewhere the shell can find it Writing A Script A shell script is a file that contains ASCII text.

Shell

Definition of the Shell Shell is an interactive environment which provides an interface to an Operating System. It gathers input from user and execute the commands. Bourne shell(sh)- 1977 The Bourne shell was introduced. The Bourne shell(sh), by Stephen Bourne at AT&T Bell Labs for V7 UNIX, remains a useful shell today (in some cases, as the default root shell). The Bourne shell was developed after working on an ALGOL68 compiler, so its grammar is more along the lines of Algorithmic Language (ALGOL) than other shells. The source code was developed in C. The Bourne shell served two primary goals: Executing UNIX/Linux commands for the operating system,i.e, command line interpreter Writing reusable scripts that could be invoked through the shell,i.e, scripting In addition to replacing the Thompson shell, the Bourne shell offered many other advantages over its predecessors such as control flows, loops, and variables into scripts, providing a more functional language to...
