How do I find my Fully Quantified Domain Name on Linux?

My domain name is for example: company1.tk

My Hostname of the server is also: company1.tk

So what would my fully qualified domain name be?

Many Thanks

You can simply type:

$ hostname

which will output like

• rahul-laptop : This will be your computer name.
• nixcraft.in : This will be your DNS domain name.
• rahul-laptop.nixcraft.in : This will be your computer name with Fully Qualified Domain Name.

And if you want can enter:

$ hostname -d

which will give you the result.
