Make sure you are using the correct edition for the level of the product. It is very good answer which explains almost all questions asked here.Note Before using this information and the product it supports, be sure to read the general information under “Notices” at the end of this information.įourth edition (December 2008) This edition applies to DB2 Version 9.1 for z/OS (DB2 V9.1 for z/OS), product number 5635-DB2, and to any subsequent releases until otherwise indicated in new editions. I tried typing Esc, then c but this does not work. It is like a hack, rather than clean solution.Īnother question is, is there a readline command for mentioned \ec sequence? I want to bound it to C-l instead because I always want to clear scrollback buffer when I clear the screen.Īnd another question is how to just type such escape sequence into terminal, to perform desired action? Then do not have to think about binding C-l to another readline command (if such command exists).
It pollutes scrollback with chunks of emptiness, so you must scroll up more, and more. What is this command? Which escape sequence it emits? How does it actually work? Does it run shell command? Or what? Again, in gnome-terminal, it seems like it works just by spiting out blank lines until prompt appear in top line of terminal. There is also readline's C-l key sequence, which by default bound to clear-screen command (I mean, readline command, not shell command). The question is, what is \ec sequence, how it differs from what clear and reset does, and why there is no separate command for it? There is also reset, which clears, but it does a little bit more than that, and it is really slow (on my system it takes more than a second, which is significant delay for humans to be noticed).Īnd there is echo -ne '\ec' or echo -ne '\033c', which does the job. In gnome-terminal clear does not clear scrollback buffer. There is clear command, according to man,Ĭlear clears your screen if this is possible, including its scrollback buffer (if the extended "E3" capability is defined). When scrollback buffer is cleared, I can just scroll to top, and will be done. Clearing scrollback buffer is handy in many ways, for example, when I wish to run some command with long output, and want to quickly scroll to start of this output.
