在 txt 文档中的每个字符串后添加一个包含预定义数据的新行

Question

This is how my txt document look like (an example);

asdf 
1234 
qwert 
56789 
zzzzz 
ccccc 

I want to add "STRING" in front each input, and a new line with "ENTER" after every input.

This is HOW I WANT it to look like;

STRING asdf 
ENTER 
STRING 1234 
ENTER 
STRING qwert 
ENTER 
...

I tried using the sed command in Linux, but my knowledge is limited.

I tried sed -e 's/$/ENTER/' -i pwdtest.txt but this dont write my "ENTER" keyword in a new line.

Im trying to make a rubber ducky script of a password list.

Please help me out solove this problem!
