Well this isn't really a Vtcl question but I am using Vtcl and trying to completely
learn Tcl/Tk, so here goes.
I want to do a tail on a file for the last line and then split up the line so I can
manipulate the data, so I thought I could do this:
set b [tail -1 filename]
set c [split $b]
then do whatever to the list that is now in $c......Well when I try this I get $b and
$c empty , I have done this in a tcl shell and I get an echo back from the tail of
what I expect however if i then say puts stdout $b the variable is empty.
What I really am trying to do is the tcl equivalent of this piece of perl code:
---------------Start Snipit--------------------------------------
$rclocal = `tail -1 /etc/rc.d/rc.local`;
($rc1,$rc2,$rc3,$ip4,$rc5,$eth) = split(/ /,$rclocal);
$ip4 = $ip;
($eth1,$eth2) = split(/:/,$eth);
$eth2 +=1;
$eth = join(':',$eth1,$eth2);
$rclocal = join(' ',$rc1,$rc2,$rc3,$ip4,$rc5,$eth);
-------------------------End Snipit--------------------------------
and then I will append this data back to the file it was read from.
Any and all help with this would be fantastic, and if there is anyone who would like
to be a "answer stupid questions pen pal" to help me learn this I would be really,
really, really, greatful.
Thanks in Advance,
Chris Hood
