Yes, I tried 'join' also but ran into the following message on using more than
1 set of double quotes:
String found where operator expected at -e line 1, at end of line
(Missing semicolon on previous line?)
Can't find string terminator '"' anywhere before EOF at -e line 1.
And, when I tried single quotes, I got:
Backslash found where operator expected at -e line 1, near "'\n\',@modules, '\"
(Missing operator before \?)
Backslash found where operator expected at -e line 1, near "n\"
syntax error at -e line 1, near "'\n\',@modules, '\"
Can't find string terminator "'" anywhere before EOF at -e line 1.
