    Do not use just less since the default is to use more -s. less seems to implement the same option. BTW: if you have an editor that allows you to exit a binary without destroing the binary, edit /usr/bin/man and replace nroff -u0 by nroff -u1 for better readable output. IIRC, there are three such strings in the binary. Commented Nov 8, 2018 at 11:24

    @JeffSchaller I do notice. The thing is that with csh I have more experience and still fighting my way through bash. Up to now I was even thinking that Bash doesn't make a distinction between environment and any other variable. Commented Nov 8, 2018 at 17:33
