Bash Shell Scripting Tutorial | Shell Scripting Tutorial

For more detailed Tutorial visit –

A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. A shell usually interprets a single line of input, but we can also create a file containing a number of lines of commands to be interpreted. This file is a program known as a shell script. The program can also contain control structures (if-then, loops). Shell scripts allow a sequence of commands to be executed automatically . Shell Scripting tutorial is designed to help beginners and professionals.

Nils Melchert

Great Tutorial! Keep it up!

Sree Parvathy

Thank you for sharing your knowledge.

I practice each and every section in my test machine as you explain. However, I find the comparison operator is not working for me.
Any idea why is it so?

[root@RHEL7encryption scripting]# cat ifelse1.sh

#! /bin/bash

count = 10

if [ $count -eq 10 ]

then

echo "Condition is true"

[root@RHEL7encryption scripting]#

[root@RHEL7encryption scripting]# sh ifelse1.sh

ifelse1.sh: line 3: count: command not found

ifelse1.sh: line 4: [: -eq: unary operator expected

Am I doing something wrong?

Anupam Nath

Thank you teacher 🙏

Shah Faisal Islam

I am extremely grateful to have watched your video.

Next week will be my training on Openwrt, Firmware Development and Lua language, in the end of which my results will secure me a job. For this, I needed to know shell scripting, and due to bashism I was told by the interviewer to learn bash shell scripting.

And today I have finished this video, and will go for the detailed tutorials on getting the job to give my best to it.
