Hello,
I am Aaditya Purani. Today i would be Presenting Shell Scripting Tutorial -1 The basic one 🙂
A shell script is a text file that contains a sequence of commands for a UNIX-based operating system. It’s called a shell script because it combines into a “script” in a single file a sequence of commands that would otherwise have to be presented to the system from a keyboard one at a time.
So, first of all if you need to cook up a shell code , you need to start with
#!/bin/sh
It means script will always run with bash. /bin/sh is an executable representing the system shell . Now, getting this overview, you might be knowing about Printing text in PHP. So let’s print Hello World .First open any text editor and type the code
Code:
#!/bin/sh
echo “Hello World!”;
Done. Now, save it as file . Now, to execute it (if you are root user) then type bash file which will print Hello world in Terminal. Now, Shell Scripting is all about commands . Let me list all files with their permission.
Code:
#!/bin/sh
echo “Lets see files”;
ls -lha
So, here is what it looks, Now if you are not as root user, then you need to give chmod +x file and then run the file. It will give executable permission. Now, let’s go more and print the version of your Linux Distribution. I use Kali Linux
Code:
#!/bin/sh
echo “Lets see files”;
ls -lha
echo “Show me version”
cat /etc/issue
That’s the output. Now you can watch a video of mine 🙂 Please don’t copy, if you want to put on your blog . Provide me credits.
