I tried it, thank you. I noticed that you missed adding a colon next to n in "ni:l:d". It works when I run `tail -f /var/log/messages | pw -d` but it only displays a single line. But if I add `-n +1` to tail, it shows all 15 lines. `tail -f /var/log/messages | cat` shows 10 lines. Is there any way I can configure pw to initially display 10 lines instead? -- konsolebox
