Perl one-liner in Windows

I have a Perl one-liner which will read a file and remove the first field of each line, which are separated by comma and dump the rest.

perl -wan -e 'for (@F) { if (/(aaa),(.*)/) {$text = $2; $text =~ s/$1// ; print "$text\n";}}'

Where aaa is in the first field of each line. This is working fine in Linux, but in Windows it is throwing an error:

Can't find string terminator "'" anywhere before EOF at -e line 1.`

Why is it behaving differently?

You might want to use double instead of single quotes. This might impose problems for quoted text "$text\n" which can be replaced by perl alternative quoting qq{$text\n}

perl -wane "for (@F) { if (/(aaa),(.*)/) {$text = $2; $text =~ s/$1//; print qq{$text\n}; }}"

In MS Windows, single quotes don't work as in Linux. You have to switch to double quotes.

perl -wan -e "for (@F) { if (/(aaa),(.*)/) {$text = $2; $text =~ s/$1// ; print qq($text\n);}}"

I used qq for the nested double quotes.
