Both are better than mine, thanks

Comment by javisol 140 weeks and 4 days ago

To be honest I can't imagine why somebody ever needs "several blank lines". To clear terminal, command 'clear' is used, or Ctrl+l if you need hotkey. If you want a script for studing try in zsh:

for i in {1..100};echo

Comment by zolden 140 weeks and 4 days ago

It's very simple, sometimes you are digging inside very large logs (cat |grep stuff). Usually I leave several blank lines between two cat|grep so I could scroll and find them easily. If I use Ctrl+L or clear I can't do that.

Comment by javisol 140 weeks and 4 days ago

BTW, I think tput clear has the same problem as Ctrl+L
