I have been wondering about this off & on for quite a while
and something today made me think of it again, so I'll ask this time.

Is there anyway to overwrite a line of output on a console with a new line of text?

Say, for example, if I was walking through a file one line at a time
and wanted to output a statement of the current line number I would use the following:

while (.......){
  #read line x
  print ("processing line: $linenum ");
}

[download]
For each line of the above, the output would output:
processing line: 1 2 3 4 5 6 7 8 ....... x
What I was curious about, is there a way to just replace the line so that only $linenum changes on output?
( e.g. 1 changes to 2 and so on )

Thanx in advance.
