To keep the forums high quality for all users, please take the time to format your posts correctly.

Use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)
Thanks.

The command of the BEGIN section executes before any input is read so the value of min is empty, to find the minimum size you can do something like this:

Code:
ls -l $1 | awk '
NR==2{
  min = $5; next
}
{
  if ($5 < min){
    min = $5;
  }
}
END {print "Tamanio menor fichero = " min; }'

Regards
