É sabido que documentos melhor estruturados são mais fáceis de entender e de ler. Um recurso simples, mas que pode ajudar e até mesmo tornar a leitura mais agradável, é colorir as páginas de documentação do sistema GNU/Linux. Para isto, precisamos definir, como abaixo, as seguintes variáveis de ambiente:
export LESS_TERMCAP_mb=$'\E[01;31m' export LESS_TERMCAP_md=$'\E[01;37m' export LESS_TERMCAP_me=$'\E[0m' export LESS_TERMCAP_se=$'\E[0m' export LESS_TERMCAP_so=$'\E[01;44;33m' export LESS_TERMCAP_ue=$'\E[0m' export LESS_TERMCAP_us=$'\E[01;32m'
Sem estas variáveis definidas, a saída do comando man ls fica assim:

O destaque do texto é obtido com o negrito do texto.
Já com as variáveis de ambiente definidas, temos a seguinte saída:

Temos aqui o uso de cor, para destacar as palavras chave e os títulos.
