You mean treated like a comment by the shell?
Well I'm not a unix guy so I can't tell for sure.
If you'd enter the command on the prompt by hand you'd have to
escape it?
You definitely do not need it for Perl.

There is another problem. Since the command in enclosed in
double quotes it is being interpolated. And the $1 gets replaced by
the first group in the last regular expression. I doubt this is what
you wanted.
Try :
print ("grep -v # *.rm | awk '{print $1}' ");
print "\n";
Do you see?
Either escape the $ :
@lines = $t->cmd("grep -v # *.rm | awk '{print \$1}' ");
or enclose it in single quotes (or better q{}) :
@lines = $t->cmd(q{grep -v # *.rm | awk '{print $1}' });
