Solution :

append the new line to the exist data in the file by using : This will append the "this is line 2" to the existing data in the file .

2. I would then like to delete the first line
echo "hello world"

Solution :

open the file using vi

$vi mfile

step 1 : now go to ex mode by clicking ":"

then type 1d

this will delete the first line from the script
or else
u can use standard commands to achieve the same
