Hi guys, Does anyone know how to set the size of the defscrollback buffer to unlimited?
Lookin' through the man page I saw no reference in setting an unlimited value: defscrollback num Same as the scrollback command except that the default setting for new windows is changed. Initial setting is 100. Clearly by setting the -k value to nothing (screen -h) will throw the help menu. A negative integer doesn't a solve the problem either, 'cause screen will print an error message and will exit. screen.c [626] if (nwin_options.histheight < 0) [627] exit_with_usage(myname, "-h: %s: negative scrollback size?", *av); The only option left is to assign a higher value to this parameter. However I learned, from the hard way, that screen -h 10000000 will just hang a system with low resources - screen consumed more than 1GB of memory! Lookin' on the source code for an answer, I noticed that screen doesn't perform any boundaries check and will try to maintain scrollback entirely in RAM. On a bad perspective this leads to (another) problem: anyone with access to a setuid screen binary (most GNU/Linux distributions have this by _default_) can literally hang a production system. So, does anyone have ideas on how to achieve this without freeze the system?
