The following sed command gives a sed unterminated `s' command. It has to do with the variable that I put in ($header):

sed -i "1s~^~$header~" $1"/main.cpp"

The following is the contents of $header:

//
// Pacman.java
// etc

In the sed command, I've used a different delimiter (~), but that still gives the error. Does anyone see what the problem is?

    Now that the question is closed: the text used as replacement in sed's s command can't include unescaped newline characters. Each newline in the replacement must be preceded by a backslash. – fra-san Jun 12 '21 at 11:13
  • @fra-san There is still the problem with the s(ubstitute) command s:pat:txt:, that whatever obscure character the script writer uses as :, the replacement string provided as an argument may also contain it, and therefore break unexpectedly. – Paul_Pedant Jun 12 '21 at 13:45
