The error message is from bash, not perl.
The exclamation point is syntactically significant to bash. Enclose the
perl script in single quotes instead of double quotes and that will
prevent bash from trying to interpret it for substitutions.
Details: bash interprets ! as a command-history substitution, similar to
the way it interprets $ as an environment variable substitution.
