Changing formatting strings used by man

jt1122 · 02-10-2024, 05:17 AM

Hi,

Code:

LESS_TERMCAP_md=$'\e[1;38;5;82m' man -P "less" ls

would show a coloured man page for ls.

As I understand man embeds the TERMCAP code into the text sent to less.

Can I change this TERMCAP code to some else, e.g. "ABC", which will be embedded in the resulting text?.

I tried

Code:

LESS_TERMCAP_md=$'ABC' man -P "less" ls >o

doesn't show ABC anywhere in the file o.

Thanks

You are not understanding.

Code:

echo $'\e[1;38;5;82m'

Code:

#!/usr/bin/bash

# Term color chart. Term need to be 90 char wide.

for i in 38 48; do
    printf "\n%25s" | tr ' ' .
    printf " %s " "printf '\e[${i};5;<num>\e[0m'"
    printf "%25s\n\n" | tr ' ' .
    for color in {0..255}; do
        if ((color <= 9)); then
            c=""$color"  "
        elif ((color >= 10 && color <= 99)); then
            c=""$color" "
        elif ((color >= 100 && color <= 300)); then
            c="$color"
        fi

        if [ "$i" = 38 ]; then
            printf "\e[${i};5;%sm  %3s  \e[0m" ${color} "FG ${c} ABC"
        elif [ "$i" = 48 ]; then
            printf "\e[${i};5;%sm  %3s  \e[0m" ${color} "BG ${c} ABC"
        fi
        
        if [ $((($color + 1) % 6)) == 0 ]; then
            printf '\n'
        fi
    done
    printf '\n\n'
done
