Hi,

I am trying to make a web base application to convert between units by using the command program called "units" http://linux.die.net/man/1/units

Basically the web application will get the input of a number, from-unit, to-unit then get the result by calling the terminal with perl. 

my $output = `units '$number $from_unit' '$to_unit'`;
print $output; # the output will be send back to the user browser

What security issue will be the consequence of this ? If any, how to solve the issues ?

Thanks
