Boa tarde estou fazendo alguns exercícios no Linux e reparei que as vídeo aulas que estou assistindo o sistema nos vídeos é colorido porém o meu é tudo de uma única cor, gostaria de saber como deixo colorido , pois facilita na compreensão das informações.

O meu é colorido, porque eu uso Sabayon Linux, baseada no Gentoo e o Gentoo tem o terminal colorido.

Eu tive uma idéia.... teste isto:

1) primeiro COPIA seu arquivo de bash, para não estragar ele:

$ cd /
$ cd ~/
$ sudo cp .bashrc    .bashrc.copia    (Isso protege seu arquivo de bash)
 

2) agora procura se no seu Linux tem este arquivo:

$ sudo ls /etc/bash/bashrc   (é assim, bashrc sem ponto)
 

3) SE TIVER, posta as linhas dele aqui....

$ sudo cat /etc/bash/bashrc
 

4. SE NÃO TIVER, crie um e o edite:

# seu editor favorito, aberto como root... aqui chamo EDITOR:
# EDITOR /etc/bash/bashrc
 

E coloque dentro do arquivo estas linhas:

# /etc/bash/bashrc
#
# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output.  So make sure this doesn't display
# anything or bad things will happen !


# Test for an interactive shell.  There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.
if [[ $- != *i* ]] ; then
	# Shell is non-interactive.  Be done now!
	return
fi

# Bash won't get SIGWINCH if another process is in the foreground.
# Enable checkwinsize so that bash will check the terminal size when
# it regains control.  #65623
# http://cnswww.cns.cwru.edu/~chet/bash/FAQ (E11)
shopt -s checkwinsize

# Disable completion when the input buffer is empty.  i.e. Hitting tab
# and waiting a long time for bash to expand all of $PATH.
shopt -s no_empty_cmd_completion

# Enable history appending instead of overwriting when exiting.  #139609
shopt -s histappend

# Save each command to the history file as it's executed.  #517342
# This does mean sessions get interleaved when reading later on, but this
# way the history is always up to date.  History is not synced across live
# sessions though; that is what `history -n` does.
# Disabled by default due to concerns related to system recovery when $HOME
# is under duress, or lives somewhere flaky (like NFS).  Constantly syncing
# the history will halt the shell prompt until it's finished.

Salve e reinicie o seu micro e o linux e teste executar no terminal algo.... Se não funcionar me avise.

Resumo esse é o arquivo que deixa colorido o terminal das distros baseadas no Gentoo. talvez funcione em outros lInux:

Veja este é um terminal em Sabayon, depois que ele executa um comando:

agora, se quiser definir cores, mudar o prompt, etc.... Isso, tem muita coisa na net para postar links, faça uma busca sobre:

"Editar .bashrc"
"Editar variável PS1"
"Personalizar o terminal Linux"
"mudar as cores do terminal LInux e do Bash" etc...

Esse editor de texto parece ser o VIM
e o arquivo /etc/fstab

Dentro do vim:

:syntax on

Não tem problema, qualquer editor de texto que ele tiver, vai funcionar como root.

o que ele precisa é editar o arquivo /etc/bash/bashrc
