in unix you can just use "grep -v '^ *#' filename > filename.new"
the equivalent perl code would look like this
#!/usr/bin/perl
while (<>) { # read lines from stdin or files named on
# the command line
print unless (/^\s*#/); # print $_ (which <> sets by default
# unless $_ starts with zero or more
# whitespace characters followed by a #
# If you only want to eliminate lines
# with # as the first character you can
# use /^#/
}
