5.12. How Many Lines to Save?
If you use the scrollbar in xterm (Section 5.11), you'll find that by default the scrollbar retains only 64 previous lines of text. You can change this by using the -sl command-line option:
% xterm -sb -sl 200 & % rxvt -sb -sl 200 &
You don't want to go crazy with the number of saved lines, though. Too many lines saved may crunch on virtual memory and also make it hard to scroll.
