I'm very new to shell scripting and am practicing how to write a script, then redirect the output into an HTML file, and then email both the script and the HTML file to myself. I have created a script called sysinfo_page, and thought it would have redirected the output into the sysinfo_page.html file, but every time I perform an ls, there is no content in the latter file.
I tried typing
but received this error code
and then on the line after that it gave me the line that has the error
Could anyone explain what's wrong with this line and if I should be doing anything else to redirect the output of the file so that the script shows up as HTML when I email myself?
Thanks.

Hi,
I am unable to get this script to work as desired. Basically, if an argument "log" is sent into the script, it outputs the result of the Make to a file output.log. However, if the argument is not passed, I want the output to be just put on screen (no redirection). See code snippet below.

html::filter
HTML::Filter(3pm) User Contributed Perl Documentation HTML::Filter(3pm)NAME
HTML::Filter - Filter HTML text through the parser
NOTE
This module is deprecated. The "HTML::Parser" now provides the functionally of "HTML::Filter" much more efficiently with the the "default"
handler.
SYNOPSIS
require HTML::Filter;
$p = HTML::Filter->new->parse_file("index.html");
DESCRIPTION
"HTML::Filter" is an HTML parser that by default prints the original text of each HTML element (a slow version of cat(1) basically). The
callback methods may be overridden to modify the filtering for some HTML elements and you can override output() method which is called to
print the HTML text.
"HTML::Filter" is a subclass of "HTML::Parser". This means that the document should be given to the parser by calling the $p->parse() or
$p->parse_file() methods.
EXAMPLES
The first example is a filter that will remove all comments from an HTML file. This is achieved by simply overriding the comment method to
do nothing.
package CommentStripper;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub comment { } # ignore comments
The second example shows a filter that will remove any <TABLE>s found in the HTML file. We specialize the start() and end() methods to
count table tags and then make output not happen when inside a table.
package TableStripper;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub start
{
my $self = shift;
$self->{table_seen}++ if $_[0] eq "table";
$self->SUPER::start(@_);
}
sub end
{
my $self = shift;
$self->SUPER::end(@_);
$self->{table_seen}-- if $_[0] eq "table";
}
sub output
{
my $self = shift;
unless ($self->{table_seen}) {
$self->SUPER::output(@_);
}
}
If you want to collect the parsed text internally you might want to do something like this:
package FilterIntoString;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub output { push(@{$_[0]->{fhtml}}, $_[1]) }
sub filtered_html { join("", @{$_[0]->{fhtml}}) }
