Generate copies of a code with just one line different in all of them

Question

I need to make a copy of a large code and replace just a name in the code. I have to do this multiple times with a list of names.

eg:

I have the names:

Jay
Joy
Jane
Juda

and I have an example code/text:

print("Hi");
Print("Hello")
print("Jay"); # here

I want the output to be like:

print("Hi");
Print("Hello")
print("Jay"); # here

print("Hi");
Print("Hello")
print("Joy"); # here

print("Hi");
Print("Hello")
print("Jane"); # here

ie, just changing one part of the code but have to repeat all the other steps.

What kind of code, in a file, variables, arrays? In a file do a loop read line by line and output your values. — Z0OM, Jul 04 '22 at 09:40

No `Juda` line? How important is it for the output to **not** have a trailing blank line? — jhnc, Jul 04 '22 at 11:49

awk '{printf("print(\"Hi\");\nprint(\"Hello\");\nprint(\"%s\"); # here\n\n",$0)}' input_file.txt

UPDATE: as I understand your comment, you need a template

template-file:
bla
bla bla
bla %NAME% bla
bla

script:
IFS=$'\n'
for i in `cat names`; do
sed "s/%NAME%/$i/" template-file
done

This will work with this example, yes. But unfortunately i have a large code ( like 20 lines) and want to make copies of them just changing one word – Abhi Raj Jul 06 '22 at 08:16
@AbhiRaj : 20 lines you might as well do it by hand – RARE Kpop Manifesto Jul 06 '22 at 23:59
@AbhiRaj You have 3 files: 1. template-file 2. names 3. script Run it in BASH. not in powershell. – gabor.zed Jul 27 '22 at 16:10
