            Bug ID: 382481
           Summary: Konsole loses scrollback history on `clear` command
           Product: konsole
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: history
          Assignee: konsole-devel at kde.org
          Reporter: shovas at gmail.com
  Target Milestone: ---

Prior to KDE4, Konsole would NOT lose scrollback history when a `clear` command
was issued.

I am logging this bug with Major severity because scrollback history is
actually lost and unrecoverable. This seems like a bad idea to me as I might
have important information there that for whatever reason I haven't saved to
file.

This behaviour takes away my ability to operate as I want to either
intentionally or by mistake.

Why should any action at the command-line affect the behaviour, display, or
data at the application level, as far as terminals are concerned?

This behaviour seems wrong-headed to me and gives a power to the remote side of
the terminal application that feels wrong.

>From googling, I've come to understand some terminals have implemented this
behaviour and it has become somewhat expected. I really have to disagree with
this as anything on the remote end could issue the control codes to clear the
scrollback and you'd lose your information. That can't be right.

Operating System: CentOS 7 (up-to-date)
KDE: 4.14.8
Konsole: 2.10.5

Thanks for considering this bug report.
