Today, all of a sudden, I thought that less doesn’t function, by default, the way I would like. So I read the manual page. These options will make “less” not wrap long lines and also will make it scroll horizontally one character at a time, instead of half the screen width. This way it’s easier to follow which long line is which.
As root, add this line to /etc/bash.bashrc.local
alias less="less --chop-long-lines --shift 1"
