Re: [Lynx-dev] More or less

Quite surprising, but indeed.

MirBSD *does* hardlink them…

… and ships more(1) only in the installer, where size is
paramount to fit into a floppy disc.

(It also ships another more implementation in .mkshrc; the current
implementation is extremely tricky, but this boils down to:

function smores {
        set +e
        local line llen curlin=0 x

        cat "$@" | while IFS= read -r line; do
                llen=${%line}
                (( llen != -1 )) || llen=${#line}
                (( llen = llen ? (llen + COLUMNS - 1) / COLUMNS : 1 ))
                if (( (curlin += llen) >= LINES )); then
                        print -nr -- $'\e[7m--more--\e[0m'
                        read -u1 x || return $?
                        [[ $x != [Qq]* ]] || return 0
                        curlin=$llen
                fi
                print -r -- "$line"
        done
}

This isn’t exactly traditional more(1) but close enough. Note the Korn
shell restores the previous set ±e state upon function exit.)

FWIW, I'm quite impressed with mksh interactively. I thought it was much
*much* more bare bones. But it turns out it beats the living hell out of
ksh93 in that respect. I'd even consider it for my daily use if I hadn't
wasted half my life on my zsh setup. :-) -- Frank Terbeck in #!/bin/mksh
