Hi, try double quotes:
The curly braces for variable expansions are good practice within strings, for reasons of readability and also to prevent variable expansion errors.
--
What happens with the single quote construct is that the variable expansions are unprotected, and therefore the shell splits variable TOKEN2 into three fields local-a and L_ARRAY. These three fields are combined with the other characters passed as parameters to the sed command, effectively like so:
This is why sed complains of an unterminated s-command.
When you use double quotes this will not happen since the variables are expanded, but not field split by the shell, since they are protected by double quotes. Double quotes also allow for simpler and easier to read code..
