My perl program is continuously running like vmstat or iostat. I would like it to mimic how vmstat/iostat rewrites the column headers as the number of rows gets near the lines per screen (or some such).

I could read things like the $= variable ($FORMAT_LINES_PER_PAGE) or some such. But how do I have my program resize based on a window resize?

thus:

When I change the size of my terminal window (xterm, maybe ssh via xterm to another system)

  1. how can window resizing information be passed on to the running perl process (such as sigwinch) then
  2. how do I resize my output parameters to match.
