Its *nix, right (Windows has much stranger command
line quoting requirements)??

# print lines containing single or double quotes
perl -n -e "print if /['"\""]/"

The first single quote is inside double quotes,
so its safe.

The first double quote terminates
the first part of the -e argument.

The second double quote is escaped, so
it becomes a literal part of the -e expression
(as long as there's no whitespace, the
argument continues).

The third double quote starts the next part
of the -e argument. And you know what the
last double quote does.

Another possible option is a here doc:

perl <<EOT
# Set filelist
@ARGV=qw(tmp.txt another_file.txt);
while(<>) {
 print if /['"]/;
}
EOT
