Well, this is interesting. From `man clear`: clear clears your screen if this is possible, including its scrollback buffer (if the extended “E3” capability is defined). -x do not attempt to clear the terminal's scrollback buffer using the extended “E3” capability. So probably I always used pseudoterminal without E3 capability. I think that in this case `clear` simply writes N enter chars, until the terminal is "cleared". IMHO this is the safest option. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/M6XXYVQAQNTHFT7F33452P6E62CO5GAM/ Code of Conduct: http://python.org/psf/codeofconduct/
