$ is matched as the end of line assertion.
BTW, if you want to match a literal $ every time (i.e. fgrep semantics),
match this pattern:
/\Q$input\E/
or use quotemeta()

i can't reproduce this with your script. it matches other lines though:
Enter a pattern:\$input
chomp (my $input=<STDIN>);
#print "input=$input.\n";
print if /$input/;
but of course these all contain literal $'s
