Let's see some basic Linux commands to get you started:

1. To view what's written in a file.

   ~ cat <filename>

   

2. To change the access permissions of files.

   ~ chmod 744 <file/folder name>

   it will change the access permissions for:

   user - read, write and execute

   groups - read-only

   others - read-only

   

3. To check which commands you have run till now.

   ~ history

   

4. To remove a directory/Folder or file.

   ~rm <file name> --> use to remove files.

   ~ rmdir <folder name> --> use to remove folder.

   

5. To create a devops.txt file and to view the content.

   ~ touch devops.txt --> This command will create an empty file.

   ~ cat devops.txt --> use this command to see what's inside the file.

   the file is empty so it will show nothing.

   

6. Add content in fruits.txt (One in each line) - Apple, Mango, Banana, Cherry, Kiwi, Orange, Guava.

   ~ cat > fruits.txt --> using this command you can directly add your content.

   or

   ~vim fruits.txt --> open up an editor and add your content.

   

7. Show only the top three fruits from the file.

   ~ head -3 fruits.txt

   

8. Show only the bottom three fruits from the file.

   ~ tail -3 fruits.txt

   

9. To create another file Colors.txt and to view the content.

   ~ cat Colors.txt --> See the content.

   

10. Add content in Colors.txt (One in each line) - Red, Pink, White, Black, Blue, Orange, Purple, and Grey.

    ~ vim Colors.txt --> add colors in the vi editor with this command.
