in thread Help with fstab

Thanks for the links but I'm new with perl so I have couple of more questions

new ( node => $node_obj, name => 'fstab' ) ;
read ( io_handle => ... )
write ( io_handle => ... )

This is the code he provides me with, but what should I write instead of "node", "name" and both "..." Any ideas? Sorry for my poor presentation of questions, but my knowledge is poor :(

    What are you talking about? Link please

      Nvm I solved that problem myself, I was just being stupid :p
      Now the problem is that I only want certain information from the fstab, but I print all of the info from fstab.
      Any clue on how to only print the information you want?

      open FILE, "</mnt/etc/fstab"; my @lines = <FILE>; print @lines;

      That's how I extract the information from it

        Dorficus:

        If I recall correctly, /etc/fstab uses whitespace to delimit the fields, so you should be able to do something like:

        open FILE, '<', "/mnt/etc/fstab"; my @lines = <FILE>; for (@lines) { my @fields = split /\s+/, $_; print "First column: $fields[0], Third column: $fields[2].\n"; }

        ...roboticus

        When your only tool is a hammer, all problems look like your thumb.
