Scripting in Linux | Ubuntu Training in Hindi | Part-16 | Ubuntu Linux for beginner-advanced
Welcome to Pal Tech Guru and in this video, we will learn about Ubuntu Linux Scripting(Script) with Ubuntu 20.04.
A shell script is a computer program designed to be run by the Unix/Linux shell which could be one of the following:
The Bourne Shell
The C Shell
The Korn Shell
The GNU Bourne-Again Shell
A shell is a command-line interpreter and typical operations performed by shell scripts include file manipulation, program execution, and printing text.
Extended Shell Scripts
Shell scripts have several required constructs that tell the shell environment what to do and when to do it. Of course, most scripts are more complex than the above one.
The shell is, after all, a real programming language, complete with variables, control structures, and so forth. No matter how complicated a script gets, it is still just a list of commands executed sequentially.
The following script uses the read command which takes the input from the keyboard and assigns it as the value of the variable PERSON and finally prints it on STDOUT.
#!/bin/bash
Script follows here:
echo "What is your name?"
read PERSON
echo "Hello, $PERSON"
Here is a sample run of the script −
$./test.sh
What is your name?
Akshay
Hello, Akshay
$
