How to replace one character with two characters using tr

Can tr replace one character with two characters?

I am trying to replace \"~\" with \"~\\n\" but the output does not produce the newline.

Answer 1

tr can only do 1 to 1 translation.

Here is one way of doing that using pure Bash:

s='"asdlksad ~ adlkajsd ~ 12345'
r=$'~\n'
echo -e "${s//\~/$r}"
asdlksad ~
 adlkajsd ~
 12345
