First Linux Script

In this first script I will show you all the details and preparations that you will need to do prior creating an running your first Linux script. I will use VIM text editor (see the tutorial in the link), but you can use any editor that you might like.

Go to the folder in which you want to create the file for the script and type:

vim test.sh

The editor will create a new file called test.sh (if the file already exist, it will be opened for editing), then input the following commands in the file:

#!/bin/sh
echo “This is my first Linux script”
echo “I will learn more advanced Linux scripts…”
echo “… but a little bit later”

Save your script and exit editor.

Make sure that your file is allowed to run by running chmod command (see the permissions tutorials: File permissions in Linux and Permissions in Linux: Octal/Absolute mode):

chmod +x test.sh

Run the script file with:

./test.sh

Octal/Absolute mode Permissions Are specified by adding them in numeric/digit mode, as they are kept in file’s inode. This way previous permission settings are lost and overwritten by the new ones.

Octal/Absolute mode Permissions

Are specified by adding them in numeric/digit mode, as they are kept in file’s inode. This way previous permission settings are lost and overwritten by the new ones.

Permissions of a file are stored in inode as bits, and they form a construct of 12 bits as follows:

(3 groups * 3 basic permissions) + 3 special permissions = 12 bits in total

Let’s say we have a file with the following permissions: rs-rSxr–

Each permission has a value assigned, to get a clear view, take a look at the tables below:

• Basic Permissions

• Special Permissions

Usually, octal mode is the fastest and easiest way to set permissions on files/folders, for the example above we have to type in  the command line:

chmode -R 6676 /file/location/example.txt

If more guidance is needed or something is missing, fell free to ask.
