Add string to list using either AWK or SED?

Question

Hi I want to be able to edit the list of name like this using either AWK or SED.

Sample input list file:

john
paul
rose
lily

Desired output:

I am john of earth;
I am paul of earth;
I am rose of earth;
I am lily of earth;

I want the semicolons at the end too. i don't want to use shell scripts of for loops.

Answer 1

With awk you can use print:

awk '{ print "I am", $1, "of earth;" }' list

or printf:

awk '{ printf("I am %s of earth;\n", $1); }' list

Answer 2

Using sed:

$ sed 's/.*/I am & of earth;/' file.txt 
I am john of earth;
I am paul of earth;
I am rose of earth;
I am lily of earth;
