Sem cor no terminal no KDE

Question

Eu postei isso aqui porque eu não sei se aqui ou o AskUbuntu é melhor para isso.

Como o título diz, não tenho cores no meu terminal no KDE Kubuntu 16.04.1.

Eu também tentei este e esta mas não tenho cor no terminal nem via ssh embora

> echo $TERM
xterm-color

De qualquer forma, a saída colorida de apt update ou ls -a , e. trabalha

Há algo que estou perdendo? Como posso obter o prompt colorido funcionando? (Especialmente perguntando porque eu quero o meu verde e a raiz é vermelha, mas nenhum dos dois funciona)

    

Answer 1

Posso estar errado, mas não vejo nenhuma sintaxe relacionada a cores no seu script

PS1='${debian_chroot:+($debian_chroot)}\[\]\u\[\] @ \[\]\h\[\]:\[\]\w\[\]$ '

Quando eu chamo seu código do meu prompt bash

PS1='\[\]\u\[\] @ \[\]\h\[\]:\[\]\w\[\]$ '

Eu vejo apenas letras brancas. Você nem tem export PS1 , o que significa que essa variável nunca afeta nada fora do script. Meu palpite é que na sua máquina antiga algum outro script era responsável pelas cores.

Para obter as cores que você publicou, tente chamar o seguinte do seu terminal

PS1='\[3[1;32m\]\u\[3[0m\] @ \[3[0;32m\]\h\[3[0m\]:\[3[31m\]\W\[3[0m\]\$ '

se funcionar, coloque

export PS1='\[3[1;32m\]\u\[3[0m\] @ \[3[0;32m\]\h\[3[0m\]:\[3[31m\]\W\[3[0m\]\$ '

no seu ~/.bashrc .
