Retrouver la coloration du terminal

Si vous n’avez pas de coloration dans votre terminal, ça vaut le coup de jeter un oeil dans le fichier .bashrc de votre dossier home :

sudo nano /$HOME/.bashrc

1	sudo nano /$HOME/.bashrc

Si son contenu est le suivant :

# ~/.bashrc: executed by bash(1) for non-login shells.

# Note: PS1 and umask are already set in /etc/profile. You should not
# need this unless you want different defaults for root.
# PS1='${debian_chroot:+($debian_chroot)}\h:\w\$ '
# umask 022

# You may uncomment the following lines if you want `ls' to be colorized:
# export LS_OPTIONS='--color=auto'
# eval "`dircolors`"
# alias ls='ls $LS_OPTIONS'
# alias ll='ls $LS_OPTIONS -l'
# alias l='ls $LS_OPTIONS -lA'
#
# Some more alias to avoid making mistakes:
# alias rm='rm -i'
# alias cp='cp -i'
# alias mv='mv -i'

# ~/.bashrc: executed by bash(1) for non-login shells.

# Note: PS1 and umask are already set in /etc/profile. You should not

# need this unless you want different defaults for root.

# PS1='${debian_chroot:+($debian_chroot)}\h:\w\$ '

# umask 022

# You may uncomment the following lines if you want `ls' to be colorized:

# export LS_OPTIONS='--color=auto'

# eval "`dircolors`"

# alias ls='ls $LS_OPTIONS'

# alias ll='ls $LS_OPTIONS -l'

# alias l='ls $LS_OPTIONS -lA'

# Some more alias to avoid making mistakes:

# alias rm='rm -i'

# alias cp='cp -i'

# alias mv='mv -i'

Ne cherchez pas plus, il vous manque les lignes pour la coloration.

Pour l’ajouter, votre fichier .bashrc doit ressembler à ceci :

# ~/.bashrc: executed by bash(1) for non-login shells.

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
        # We have color support; assume it's compliant with Ecma-48
        # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
        # a case would tend to support setf rather than setaf.)
        color_prompt=yes
    else
        color_prompt=
    fi
fi

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi
unset color_prompt force_color_prompt

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
    ;;
*)
    ;;
esac

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'
    alias dir='dir --color=auto'
    alias vdir='vdir --color=auto'
    alias grep='grep --color=auto'
fi

alias ll='ls -la'
alias la='ls -a'
alias tar='tar -czvf'
alias untar='tar -xzvf'
alias trouver='grep -rl'

# ~/.bashrc: executed by bash(1) for non-login shells.

# uncomment for a colored prompt, if the terminal has the capability; turned

# should be on the output of commands, not on the prompt

force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then

if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then

# We have color support; assume it's compliant with Ecma-48

# (ISO/IEC-6429). (Lack of such support is extremely rare, and such

color_prompt=yes

else

color_prompt=

if [ "$color_prompt" = yes ]; then

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

else

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

unset color_prompt force_color_prompt

# If this is an xterm set the title to user@host:dir

case "$TERM" in

xterm*|rxvt*)

PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"

;;

esac

# enable color support of ls and also add handy aliases

if [ -x /usr/bin/dircolors ]; then

test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"

alias ls='ls --color=auto'

alias dir='dir --color=auto'

alias vdir='vdir --color=auto'

alias grep='grep --color=auto'

alias ll='ls -la'

alias la='ls -a'

alias tar='tar -czvf'

alias untar='tar -xzvf'

alias trouver='grep -rl'

J’ai ajouté quelques alias à la fin du fichier, comme vu dans ce précédent article.

Et si votre fichier .bashrc contient déjà toutes ces lignes mais que la coloration ne fonctionne pas, il faut souvent dé-commenter* la ligne :

#force_color_prompt=yes

1	#force_color_prompt=yes

* enlever le dièse en début de ligne

c'est pas mon blog

mais c'est bien quand même
