Concatenating two string variables in bash appending newline
bash, linux, shell
Solution
New lines are very much there in the variable `"$final_list"`. `echo` it like this with double quotes:
echo "$final_list"
url1
url2
url3
OR better use `printf`:
printf "%s\n" "$final_list"
url1
url2
url3
Problem
I have a variable `final_list` which is appended by a variable `url` in a loop as: ``` while read url; do final_list="$final_list"$'\n'"$url" done < file.txt ``` To my surprise the `\n` is appended as an space, so the result is: ``` url1 url2 url3 ``` while I wanted: ``` url1 url2 url3 ``` What is wrong?
