linux - Apply shell script to strings inside a file and replace string inside quotes -

suppose have file greeting.txt(double quotes inside file, 1 line):

"hello world!"

and file names.txt(no double quotes, many lines, show 2 here example):

tom mary

then want create bash script create files greeting_to_tom.txt:

"hello tom!"

and greeting_to_mary.txt:

"hello mary!"

i'm quite newbie in shell script, after piece searched, tried:

greetingtoall.sh:

#!/bin/bash filename="greeting_to_"$1".txt" cp greeting.txt $filename sed -i 's/world/$1/' $filename

and @ command line type:

cat names.txt | xargs ./greetingtoall.sh

but tom recognized , it's wrongly replaced $1. can me task?

if create greetingtoall below:

greeting=$(cat greeting.txt) while read -r name;    echo "$greeting" | sed "s/world/$name/" > "greeting_to_$name.txt" done < "$1"

you can call as:

./greetingtoall names.txt

depending on you're doing, might better idea parameterise script take greeting file choose:

greeting=$(cat "$1") while read -r name;    echo "$greeting" | sed "s/world/$name/" > "greeting_to_$name.txt" done < "$2"

then can call as:

./greetingtoall greeting.txt names.txt
