I am using
screen in terminal and need to increase scrollback buffer (from the original size which is just as large as the current window). I came across this question but the solution seems not to work for macOS.
I made a
~/.screenrc file with the content beeing
startup_message off defscrollback 5000
The startup message is gone now, but buffersize is still the same. Is
screen different in macOS? I am using High Sierra.
