Clear Screen
Hi, I use bash on Xterm. While working you press Ctrl-L, so that the screen gets cleared and you see the currently line only. But you may want to see the last outputs/prints. However, if you do a Ctrl-L/clear command, these prints go away. In that case, what can you use so that you clear the screen of the prints/outputs from last command. But in case you want to see the last output, you can just go scroll up/pageup. I looked at the bash Xterm manpage but this info is not available.

Yep, looks like xterm doesn't push the screen content into the scrollback when clearing the screen, and I can't see an option for it either. You may want to try mintty, which does do what you expect (and which doesn't require X).

I looked at the bash Xterm manpage but this info is not available. The closest I recall offhand is the xterm tiXtraScroll resource (which would be useful if you were asking about running vi, etc). But a screen-clear is done without causing any scrolling action. By the way, the clearing of the screen on ctrl/L is not done by xterm. (PuTTY does this, in case you're mistaking it for xterm, otherwise I'd assume bash is doing it). -- Thomas E.

PuTTY's behaviour of interpreting ^L as formfeed is due to its SCOANSI mode being enabled by default. (Strange that the VT100 interpreted ^L, which of course is ASCII formfeed, as linefeed instead.)
